ELISA Results
The graph at the right displays a basic breakdown of the absorbance data acquired at the end of the ELISA assay. The four columns indicate: From the values of each bar, we can get some information about the effectiveness and background absorbance of this assay. Ideally, the 'no his-HRP' control should display baseline absorbance because HRP is the molecule responsible for oxidizing TMB and turn blue which has highest absorbance in 450nm, indicating the existence of T4 Ligase. regardless to whether HRP and TMB exist, there are some chemicals in the solution that display some background absorbance. so this should be treated as a loose baseline to compare the rest of the data to. The 'no myc' and 'no T4L' controls both produced similar levels of fluorescence to each other. This is consistent with the idea that in both of these controls, there should be no T4L bound to the plate (either because it was not present or had nothing to bind to). Even so, it seems that the his-HRP, even without T4L, was able to bind in some amount to the plate and increase the absorbance signal as compared to the no his-HRP case. It is possible that his would be able to interact with the myc antibody or attach to the plate even with the blocking buffer present. These controls indicate that the absorbance signal must be higher than about .2 absorbance to effectively indicate a working ELISA assay. In fact, the 'pos' control gives a absorbance signal of about .27 absorbance, the highest of the four controls. This may indicate that the T4 ligase was effectively bound and measured by the two antibodies. However, the standard deviation from this control is so large that it overlaps with the 'no myc' and 'no T4L' controls. This variation may be due to the differing concentrations of T4 ligase which were added to the wells, or other factors which would require repeats of this experiment.
 * 1) No T4L - T4 ligase was not added to these wells, meaning there was nothing for the antibodies to bind in the assay.
 * 2) No Myc - The Myc antibody was not added to these wells, meaning there was nothing to bind the T4 ligase to the plate.
 * 3) No his-HRP - The his antibody conjugated to HRP was not added to these wells, meaning that the T4 ligase was not attached to a second antibody, and also that no reaction would occur with the HRP to produce a absorbance signal.
 * 4) Pos - This is the positive control, so all reagents should have been added at the appropriate parts of the protocol. It should produce the largest absorbance signal if the T4 ligase does contain both myc and his tags and was successfully bound.

Suggestions for ELISA
1. Problem: Absorbances remain unchanged/increases with decreasing protein concentration Possible cause: Protein concentrates saturates available antibody Solution 1: Reduce protein concentrations below 1/10000X Solution 2: Perform a second purification step Solution 3: Increase antibody concentrations available to bind protein (primary detecting (anti-His) or primary capture (anti-Myc))

2. Problem: Absorbance of positive control is not significantly different from negative controls Possible cause: steric hinderance of dual tag construct. Solution 1: add a ALA-6 linker between two tags. Solution 2: put tags on the opposite side of the protein. second possible cause: background noise. solution 1: do more replicates.

TECAN Analysis
Cells did not show differential growth rates with arabinose induced constructs, as expected. No growth was observed for many wells that are near the edges of the TECAN plate; recommend to not use edge wells in future analyses.

4/19/2010

 * analyze TECAN data, maximize TECAN protocol
 * TECAN data showed significant edge effects. Recommended to not use outer rows and columns
 * I have no clue how to derive the actual growth rate. Tried some logistic equations (a*b)/(a-(b-a)*Exp(-c*t)) and nonlinear regression but my system keeps blowing up, regression looks bad, etc.
 * There are a lot of forms of logistic equations you can use. E.x. K / (1 + exp(a + b*x), the differential form dN/dt = r*N(K-N)/K, etc. If anyone has a copy of Mathematica or SPSS, try to play around with it.
 * develop ELISA protocol

Wei-Chun Hu 23:47, 17 March 2010 (EDT)
Chose sbb13-1 and sbb13-2 for sequencing. Put into clotho.

Protocol
Awaiting sequence results. Repeat Miniprep if needed. Redo sbb13 (as I predicted), depending on what JCA says.

Products

 * sbb11-1, sbb11-2, sbb11-3, sbb11-4 - 4 clones picked from sbb11 plate
 * sbb13-1, sbb13-2, sbb13-3, sbb13-4 - 4 clones picked from sbb13 plate
 * Very (VERY) rough estimation of transformation efficiency:
 * sbb11 - (87*17 cells)/(((50 ng))*(1 uL/8.5uL)) = 251 cells/ng insert = 23 cells/ng plasmid
 * sbb13 - (42*17 cells)/(((80 ng)*2)*(1 uL/8.5uL)) = 38 cells/ng insert = 17 cells/ng plasmid
 * sbb11 transformed nearly 10x as efficiently (gramwise), and approximately the same efficiency molewise (1812/226).
 * Choose: sbb11-2, sbb13-4 for sequencing
 * Lanes 2-5 look fine (Expected: 1727/684 (EcoRI/XhoI), actual ~1700/650) - chose sbb11-2 (lane 3)
 * Lanes 10-13 - (Expected: 2170/1827 (EcoRI/BamHI), actual (sbb13-4): ~2500/1750) - need more resolution to be sure. Chose sbb13-4. If it fails, choose sbb13-1 or sbb13-2.

Protocol
''Assume white colonies are present. This may or may not be a reasonable assumption.''

Miniprep purification of DNA using Macherey-Nagel Nucleospin Kit
MINIPREP (1mL - 5mL) Procedure for Plasmid DNA Purification


 * Pellet the cells (for individual cultures)
 * 1) Pellet around 1.5 mL to 3 mL saturated culture by spinning full speed, 30 seconds.
 * 2) Dump supernatant, repeat to pellet another 1.5 mL (for a total of 3 mL if desired)


 * Pellet the cells (for 24-well blocks)
 * 1) In 327, weigh the block on the scale, fill a dirty block with water to the same weight
 * 2) Use the Allegra centrifuge to spin at 5500rpm for 4 minutes
 * 3) Dump supernatant
 * 4) You will need to transfer the cells to microcentrifuge tubes after resuspension in A1 in the alkaline lysis section below


 * Do an alkaline lysis
 * 1) Add 250uL of A1 buffer into each tube. Resuspend the cells using a vortexer.
 * 2) Add 250uL of A2 buffer (a base that denatures everything and causes cells to lyse). Gently mix up and down. Solution should become clearer.
 * 3) Add 300uL of A3 buffer (an acid of pH ~5 that causes cell junk - including protein and chromosomal DNA - to precipitate, and leaves plasmids and other small molecules in solution). Slowly invert a few times, then shake.
 * 4) Spin in centrifuge at top speed for 5 minutes.
 * 5) Label columns with an alcohol-resistant lab pen.


 * Purify DNA on a column
 * 1) Pour liquid into columns, and place the columns into the centrifuge. Spin at full speed for 15 seconds.
 * 2) Dump liquid out of the collectors under the columns (the DNA should be stuck to the white resin)
 * 3) Wash each column with 500 uL of AW buffer.
 * 4) Spin in centrifuge at full speed for approximately 15 seconds, then flick out the liquid again.
 * 5) Wash with 750uL of A4 buffer (washes the salts off the resins).
 * 6) Spin in centrifuge at full speed for approximately 15 seconds and flick out liquid again.
 * 7) Spin in centrifuge at full speed for 90 sec to dry off all water and ethanol.
 * 8) Label new tubes and put columns in them.
 * 9) Elute them by squirting 50uL of water down the middle of the column (don't let it stick to the sides).
 * 10) Spin in centrifuge at top speed for 30 seconds.
 * 11) Take out columns and cap the tubes.
 * 12) Clean up - note the A1 buffer is stored at 4degC and all the rest at room temperature.

A public service announcement
Jim will be gone early on Wed and Fri for personal matters.

"Suggested" Protocol

 * Immediately set up 4 analytical gels for all PCRs.
 * Select the better out of (4ABC2 [h2o] or 4ABC3 [DMSO]) and (JHD [7D] or JHD2 [5D]).
 * Try to get the gels run ASAP. I really don't have much time.
 * If at least 2 out of 4 are satisfactory, do a zymo cleanup (if I leave at 3, that's probably as far as I will get.)

SOE
Do PCR starting from 3ABC with alternate temperature settings. 2 PCRs done, one with H2O, one with added DMSO. See Template:SBB-Protocols_PCR2.

PCA
Prep. gel done for 5D. Product is present but in unacceptably low concentration (3rd lane from right): Zymo gel purification still performed. Eluted with 10 uL ddH2O into 7D. Both 5D and 7D were used for Re-assembly. Abnormally large quantities of both (5 uL) were used for the PCRs, in place of water: '''Note that I will need to do another digestion assuming the next prep. gel turns out right (hence, the 5D step is basically useless). It should be obvious why.'''
 * 1) 37 uL 32 uL ddH2O
 * 2) 5 ul 10x expand buffer
 * 3) 5 ul 2mM dNTPs
 * 4) 1 ul oligo mixture (100uM total, mixture of oligos after combination of 100uM stocks)

 * JHD (PCR) = uses 5 uL of 7D
 * JHD2 (PCR) = uses 5 uL of 5D

Protocol

 * The big picture: Proceed with PCA. Do not proceed with SOE.

Protocol: PCA

 * 4) (do NOT put isopropanol.)
 * 5) transfer into the Zymo column inside a collection tube (small clear guys)
 * 6) spin through, discard waste.
 * 7) Add 200 uL of PE buffer (which is basically 70% ethanol)
 * 8) spin through, discard waste.
 * 9) Add 200 uL of PE buffer
 * 10) spin through, discard waste.
 * 11) spin for 90 seconds, full speed to dry.
 * 12) discard collection tube

24uL ddH2O 3.3uL 10x Expand Buffer "2" 3.3uL dNTPs (2mM in each) 1uL OJIMH011, 10uM (dilute 100 uM stock) 1uL OJIMH014, 10uM (dilute 100 uM stock) 0.5uL Expand polymerase "1" 0.5uL Template DNA
 * Elute the DNA in 50uL of water in a LABELED eppendorf tube
 * Dilute 10 uM stocks of OJIMH011 and OJIMH014.
 * Set up your second round of PCR as a normal 33uL reaction using the eluted mixture of fragments as template:

Small-Frag Zymo Cleanup
The following procedure removes the polymerase, dNTPs, buffer, and most of the oligonucleotides from a PCR reaction for fragments smaller than 300bp. It also will remove the buffer and restriction enzymes from a restriction digest reaction.


 * 1) Add 100 uL of Zymo ADB buffer (brown bottle) to the reaction.
 * 2) Transfer into the Zymo column (small clear guys)
 * 3) Add 500uL of Ethanol and pipette up and down to mix
 * 4) spin through, discard waste.
 * 5) Add 200 uL of PE or Zymo Wash buffer (which is basically 70% ethanol)
 * 6) spin through, discard waste.
 * 7) Add 200 uL of PE or Zymo Wash buffer
 * 8) spin through, discard waste.
 * 9) spin for 90 seconds, full speed to dry.
 * 10) elute with water into a fresh Eppendorf tube

Amplification
Now, you need to do an amplification of the correct full-length chunks. Clean up the assembly reaction with a zymo column; don't bother running it on a gel - it'll be a smeary mess and won't really help you. Save the purified product in case this step fails! For the amplification reaction, do a normal phusion program with 1 ul of the cleaned up assembly reaction as template, and using the outermost oligos for the chunk. That is: Recipe Program
 * 1) 1 ul each outer oligo [sbb11 F/R] (10 uM)
 * 2) .5 ul phusion
 * 3) 10 ul 5x phusion buffer
 * 4) 5 ul 2mM dNTPs
 * 5) 32.5 ul H2O
 * 1) 2 min initial denature at 94oC
 * 2) 30 sec denature at 94oC
 * 3) 30 sec anneal at 60oC [This should be high, as your outer oligos now have a huge overlap with the correct product]
 * 4) 30 sec extension at 68oC
 * 5) repeat 2-4 30 times total

Protocol
Resuspend lypophilized DNA. Oligo stock is 100 uM, dilute to 10 uM. Appropriate components (see [[Media:2-17-10-cloning-PCR.pdf]]) were added to three Eppendorf tubes. Transfer to PCR tubes at end. DNA polymerase was added to the mastermix. Oligos for PCA were provided as mixture (100 uM, M), forward (10 uM, F), and reverse (10 uM, R). The Template:SBB-PCA protocol was used.
