Sequencing sign up

1. Sign up to sequence on WebSeq.
2. Click on R2R Signup (list) (found on the left hand side) and fill out required information.
3. Answer YES for request cleaning service.
4. Bring the given reference number with you, check in your samples when you drop them off, and bring back sample racks. Alternatively, you can bring your samples over to the Core and sign up there.

  • Carry samples on ice to the Core.


  • Before starting, take Qubit HS (for low-concentration samples up to 100ng/μL) or BR kit (for samples 2-1000ng/μL) from fridge and thaw buffer and dye to room temperature.
  • The dye is light-sensitive; make sure it is wrapped in foil and/or covered.
  • Use Qubit assay tubes only (we have 0.65mL Axygen tubes).

Sample Preparation
1. Make master mix of buffer and dye in the ratio of 200μL buffer : 1μL dye per sample. Take into account the number of samples you have and the 2 standards, and add extra for error.
2. Make STD-1 by adding 200μL of mix to a tube (1μL dye and 199μL buffer). This is the blank.
3. Make STD-2 by adding 190μL of mix and 10μL of standard to a tube.

  • For HS kit, use the 10ng/μL standard (100ng).
  • For BR kit, use the 100ng/μl standard (1000ng).

4. For all other samples, add 199μL mix to each tube, then add 1μL DNA sample. This can be adjusted to 198μL mix and 2μL DNA - you will just have to account for the difference when you do the concentration calculation.

Qubit fluorometer

  • Fluorometer can be found either at the Core ($5 charge) or in the Alfaro lab on the 2nd floor.
  1. Turn on machine either by plugging it in or tapping the screen. Choose the appropriate program.
  2. To blank machine, place STD-1 tube into machine, close lid, and press measure.
  3. Place STD-2 tube into machine, close lid, and press measure.
  4. Record the reading for STD-2. It should be around 500 for HS or 5 for BR.
  5. Remove STD-2 and begin measuring and recording readings for all other samples.
  6. At the end of process, measure STD-2 again. Reading should still be around 500 for HS or 5 for BR. If it is not, start the process over again (re-read standards and DNA tubes, etc.)

Concentration of sample = QF x (200/volume of DNA used)

  • QF is the value given by the fluorometer
  • Remember to look at the units given by the fluorometer and take that into account when making your final calculation.

Shortcut using 1μL of DNA:

  • HS: QF / 5 = ____ ng/μL
  • BR: QF x 200 = ____ ng/μL


This is similar to the Qubit but uses the PicoGreen kit and Victor plate reader instead. Again, the dye is light-sensitive, so make sure it is wrapped in foil or covered.

Make sure 1x TE and standards are prepared. Prepared 1x TE should be above the PCR machines and the standards should be in the fridge. If they are out:

  • Dilute the concentrated (20x) buffer from the kit 20-fold with dH2O.
    • For example: 20x buffer * x = 1x buffer * 200mL
    • x = 10mL concentrated buffer. Add 190mL dH2O.
  • Prepare standards (makes 50μL):
μL stock
1x TE
50 0 100
25 25 50
5 45 10
2.5 47.5 5
0 50 0
    • Can use fewer standards or make additional standards with smaller concentrations if desired.
    • Store leftover standards in the fridge.

To prepare DNA samples in plate:

  1. Take dye and prepared standards from fridge and let them thaw to room temperature.
  2. Make master mix of 1x TE and dye in the ratio of 200μL TE : 1μL dye per sample. Take into account the number of samples you have and the number of standards, and add extra for error.
    1. This can be poured into a reservoir if using a multichannel pipet. Remember to keep it covered.
  3. Obtain black PerkinElmer 96 well plate.
  4. Add 1-2μL of each standard in a row. Add the same volume of DNA sample into the remaining wells.
    1. The Victor machine reads plates horizontally across rows, not down each column.
  5. Add 198-200μL of TE/dye mix to each well and pipet mix.
  6. Incubate plate for at least 5 minutes in the dark.

To read and calculate sample concentrations:

  1. Place plate in Victor plate reader machine.
  2. Open Wallac Victor 3 program.
  3. Click the second button at the top, "Define plate map and start...". Choose your program.
    1. You may have to create your own folder and copy or customize a PicoGreen program from another folder.
  4. Define which wells on the plate are measured vs. empty by clicking on individual wells and/or selecting across rows. Start the program.
  5. After the plate is done reading, click the first button at the top, "Explore protocols and results". A screen should show up with a list of all the plates run under the program you ran.
  6. Double click the file you ran. Go to File > Export. Save the document as an excel file on a flash drive and eject.
    1. Do not name the file with any periods. It will interpret text after periods as the file extension.
  7. On another computer, open the Excel file. Go to the first sheet.
  8. In the last column, you will see PicoGreen values. These must be extrapolated to concentrations:
    1. Next to the values of the standards, enter the standard concentrations (0-50).
    2. Insert a scatter plot. Right click the box and click "Select Data". Under "Legend Entries", click the "Add" button. For Series X values, select the standard concentrations you entered. For Series Y values, select the PicoGreen values that the standards correspond with and press OK. A scatter plot should show up with the points in a relatively straight line.
    3. Click on the points on the graph to select all of them. Right click and select "Add trendline". Also click the options to show equation and R2. These should now show up on the graph. The R2 value should be close to 1.
    4. In a new column, enter the formula to calculate the concentration of each sample. For example, if your equation is y = 500x + 1000, the formula in the cell should look like " =(H2-1000)/500 ". This gives you the concentration of the sample in the first well. Copy the formula down the column to calculate the concentrations of the rest of the samples.

The Excel sheet should look something like this, where the red text indicates user inputted data and the last column outputs the concentration of the samples:

  • Remember to remove plate from the machine when you are done and clean it using bleach and UV.


  1. Quantify samples (use Nanodrop, Qubit, or PicoGreen) and record concentration.
  2. Using dH2O, dilute 1ul of sample to ~ 2.5-3 ng/uL. If using Nanodrop numbers, use 5-10 ng/uL to account for error. The total final volume must be at least 3ul.
  3. Take samples on ice to Core (CHS 36-125). Sign up on the sheet and place samples on a rack. Label the rack and store in freezer.
  4. To check for results, log onto WebSeq and click "Genotyping" on the left side menu.


  • Maximum number of samples for DNA High Sensitivity and RNA Pico chips is 11. Other chips are 12 samples.
  • Try to fill up chip as much as possible by coordinating with other labs.
