7 July 2009 Lab Meeting
† Announcements
 * Attending:  Jessie, Hussam, Ajani, QQ, Jaephil, Jane, MinCheol, Cathie, Alex.
 * Missing: Sonali, Brendan,
 * Presentation: Supplies/Chemicals Review Discussion. We will discuss what we need, what should be tossed out, etc.
 * Assume contamination is in the reagents. Buy inhibited reagents. Buy smallest possible quantities. Toss out or label old bottles for DNA only. Label new bottles RNA only. Buy new inhibitor removal columns, one pack to start with. If we still have contamination after this change, we will look into cleaner deinhibition protocols.
 * Cathie to throw out old student samples. And old kits.
 * New clean hood. Install/ cleaning sometime soon.

† Flu R01
 * Signed CDC MTA.
 * Integration: Spec? On chip? Jane will look into it.
 * QQ will work on the initial integration steps of SPE + RT (resevoir)+ PCR. Cutter plotter? Faunhofer Chip serpentine channel.
 * RNA extraction troubleshooting.
 * Try clean fabrication of chips and monoliths.
 * Try RNAseH wash through.
 * Absolute Quantification assays:
 * A primers look good at this point. Van Elden 2001.
 * Jessie should learn SEM.

† Virus concentration (upstream from the assay.) † Coulter Flu Fraunhofer Project
 * QQ - HM - JZ - Chip Integration.
 * How to read? Color, sensitivity? Alignment. Check with JD.
 * IBC for Fraun flu. waiting?
 * Brendan can come to Fraun Flu meetings if he wants....as primer design goes.
 * Ajani should come to Fraun Hot Dog meetings to learn how to make straws. Alex will train him.

†RNA project † COBRA paper 1: Evap with Sol Gel substrate. paper 2: Covap with PMA, Rhodamine, PS beads?...virus...? - Rhodamine experiments done - Signals are similar between with and without GNP - Rhodamine binds poorly to gold - try GNP-pMA next. R6G-silver NP. - Need to redefine hypothesis † Biointerfaces group † CIMIT- Colson Grant † PCR the repeatebility has been comfirmed. † RCA/HDA
 * Call Natalia.
 * Update on concentration of live bugs?
 * Evap system (JD and JZ)
 * Let's get this to a point where we can publish and move on
 * fabricated SU-8 mold with Herringbone grooves.
 * Brett took a photo of the device for the paper, but will repeat
 * Jason coated thin gold on the surface of the PDMS mold, and will take SEM images for the sieves. --->SEM down
 * draft paper2 for the submission to "Biophysical Journal" has been started.
 * ran the experiment using BSA to prevent non-specific binding.
 * IRB submitted.
 * Cathie working on the companion BU IRB form for exemption.
 * QQ: PCR 2 paper draft.
 * CMK: PCR 1 draft
 * DONE with PEG attempts.
 * PEG-coating protocol developed - TROUBLESHOOTING.
 * on-chip experiment with blank chip without PEG,BSA. It works with expected lower efficiency
 * on-chip experiment with PEG-coated chip without PEG,BSA in reagent. It does not work, or the product is under the detection limitation of bioanalyzer.
 * testing inhibition of PEG-NH2 on AB+
 * testing inhibition of NHS and EDC on AB+
 * QQ and MM: look back at flu PCR. Recall the repeatability. Decide course of action with Sonali. See what you can do to do "real" samples soon. One pot? Two steps necessary instead?
 * optimization of PEG and BSA concentration for on-chip flu PCR
 * Start planning R01 for Submission on 10/5/09. MM, JD, CMK.
 * Getting solution back out is still an issue.
 * Integrated chip worked (19th). Accumulating multiple runs. (Check into primer lifetime)
 * Evaporation problems near edges. Maybe design change?
 * Teflon issue with the enzyme? Check into it.

† Silica Optimization (Lambda):
 * St. Curve for Abs Quant Assay.
