20 October 2009 Lab Meeting
- Presentation:Dr. Tushar Bansal, post doc applicant. 2pm, please BE ON TIME.
- PAPERS Drafted before MicroTAS
- Posters for MicroTAS
‡ Flu R01:Integration
- New design - address evaporation loss, Reagent delivery and storage solution. Consider marginating flows?
† Sample Concentration (Lead: Jane, Team: Jaephil)
- Up to high 10^7 for positive control. Silver substrate no signal.
- Jane working on the cell lysate control: plan to have Cassidy's help on plaque assay while I'm away.
- New cell passage from frozen - the old one is beyond passage 30.
- Main loss is at the outlet/sample collection: tangential filtration design in drawing stage.
- Contacted EC Shaw about rubber stamp mold for new design for evaporation.
- Set up COMSOL and StarCD, look for governing equations for simulation of evaporation.
- Committee meeting setup
† SPE Column Optimization for RNA. (Lead: Sonali, Team: Hussam, Jessie, Brendan)
- Design three straight channels. A: std channel we already use. B: widest channel possible, C: something in between.Send out masks by 10/21, functional chips to be delivered by 10/26. [Update] functional chips ready by 10/21-22, Experimental results of channels to be delivered on 10/27 [Hussam/Jessie]
- Load DNA in a straw of 5,50,100ul SPE, quick test of hypothesis: more SPE = more DNA, To be repeated with Alex and Mark
- New virus prep (JC, 6/11/09), getting Ct's of 27 for 1:16 dilution and 28 for 1:64 dilution. Use more diluted sample for future optimization experiments?
- Tried 2 more chips with 3X 0.15um Silica. SPE was coming out even at 2ml/hr flow rate.
- Running no silica and no SPE chips with virus.
† PCR - CMI (Lead: Qingqing)
- QQ will work on the initial integration steps of SPE + RT (resevoir)+ PCR.
- PCR2 Paper formatted for LOAC this week.
- CMK: PCR 1 draft. Analytical Chem. MCK is running more simulations.
† HDA (Lead: Jaephil, Team:Sonali)
- Start planning R01 for Submission on 2/5/10. MM, JD, CMK.
- JD will train QQ how to make HDA chips. This may entail moving from cutter plotter to embossing steps. JD and QQ to meet ASAP to plan the tech transfer.
- Paper submitted 10/6.
‡C. diff Project (Cathie, Sonali, Satish Singh, Lisa J., His post doc )
- Sonali to train Lisa on SPE.
- QQ to run test PCR on chip with genomic DNA and Toxin B primers.
‡ Coulter Flu Fraunhofer Project (Lead: Sonali, Team: Sonali, Jessie, Cathie, CMI Folks, Qingqing)
- Meeting 9am Monday (every other week)
‡ Agilent Automated Sample Preparation (Lead: Alex)
- Paul finishes work on nozzles on Wednesday. Then first testrun and rewriting of software for "HotDog"-Run on Machine.
- First Draft of Paper (Lysis of Yeast Cells) ready. Work ongoing on "Conclusion"-Section of Paper.
‡ COBRA (Lead: Jaephil, Team: Cathie, Jane for virus only, PHO folks)
- Metal piece modification for the integration - Parts distored and is begin fixed.
- paper 1: Evap with Sol Gel substrate. Not integrated. MSSA, E coli.
‡ Biointerfaces group (Lead: MinCheol, Team: Cathie, MCK, Wong and Meller folks)
- New experiments happening now.
- Cathie will submit paper inquiry.
‡ CIMIT- Sepsis (Lead:Cathie, Team:TBA)
- IRB approved.
- Cathie submitted the companion BU IRB form for exemption. Revised, still still waiting.
‡ PATH Grant (Lead:Cathie, Team:Frank, Sean, Mark, Jake Trueb (ME), Suma)
- Phone meeting with PATH this week. 10/13.
- UGs purchasing parts for straw machine for 709.
- UGs purchasing reagents for running extraction experiments and doing PCR.
