==27 October 2009 Lab Meeting== | |||
* Attending: <br> | |||
* Missing:<br> | |||
* Presentation:Special Guest. Dr.Jonathan Simon. Cathie will present for 15 min. '''2pm, PLEASE BE ON TIME.''' <br> | |||
<br> | |||
'''‡ Announcements'''<br> | |||
* Oakridge deadline is 1 Feb 2010. <br> | |||
* '''PAPERS Drafted before MicroTAS''' Are we done with this? <br> | |||
* '''Posters for MicroTAS''' Can Jaephil take them all? <br> | |||
<br> | |||
'''‡ Flu R01:Integration''' <br> | |||
* New design - address evaporation loss, Reagent delivery and storage solution. Consider marginating flows? <br> | |||
<br> | |||
† Sample Concentration (Lead: Jane, Team: Jaephil) <br> | |||
* MDCK Cells are not propagating. Try troubleshooting efforts. Sonali will do on Monday. <br> | |||
* Cassidy needs to see plaque assay again - so when cells are up, she needs training. <br> | |||
* Up to high 10^7 for positive control. Silver substrate no signal. <br> | |||
* Jane working on the cell lysate control. <br> | |||
* Main loss is at the outlet/sample collection: tangential filtration design in drawing stage. <br> | |||
* Contacted EC Shaw about rubber stamp mold for new design for evaporation. <br> | |||
* Set up COMSOL and StarCD, look for governing equations for simulation of evaporation. <br> | |||
* Committee meeting setup <br> | |||
<br> | |||
† SPE Column Optimization for RNA. (Lead: Sonali, Team: Hussam, Jessie, Brendan) <br> | |||
* 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]<i> functional chips ready by 10/21-22, Experimental results of channels to be delivered on 10/27 </i> [Hussam/Jessie]<br> | |||
* STD recipe, STD silica beads, just A,B, and C. <br> | |||
* controls for these: empties, non-silica monolith and full silica monolith, std. recipe. <br> | |||
* Load DNA in a straw of 5,50,100ul SPE, quick test of hypothesis: more SPE = more DNA, <i>To be repeated with Alex and Mark </i> <br> | |||
*'' Look into modifying Alex's pneumatic setup for the PATH guys. Instead of building the straw array over here NOTE: Sean'' <br> | |||
*PLanning net silica per channel experiments. with 700nm, 3x possible. Deliver around 11/5/09.<br> | |||
<br> | |||
* 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? Channels were 700nm silica/1X. pfu/ml is 10^6. <br> | |||
* Tried 2 more chips with 3X 0.15um Silica. Chips are breaking b/c of no crosslinking. SPE was coming out even at 2ml/hr flow rate.<br> | |||
* Running no silica and no SPE chips with virus. (JC/RNA)<br> | |||
<br> | |||
† PCR - CMI (Lead: Qingqing) <br> | |||
* QQ will work on the initial integration steps of SPE + RT (reservoir)+ PCR. <br> | |||
* test liquids to fill the empty channel(Mineral oil,Water) | |||
* Deep reservoir design | |||
- deformation during bonding | |||
- fabrication difficulty | |||
- Fluidic control difficulty | |||
* third generation design to solve these problem | |||
- the mold and the chip has been made, and will be tested this week. | |||
* PCR of C.Difficile DNA | |||
- ATCC DNA and Primer pairs for both toxin A and B has been ordered. | |||
- real-time PCR has been done on ABI, waiting for the result. | |||
* PCR2 Paper formatted for LOAC this week. <br> | |||
* CMK: PCR 1 draft. Analytical Chem. MCK is running more simulations. <br> | |||
<br> | |||
† HDA (Lead: Jaephil, Team:Sonali)<br> | |||
* Start planning R01 for Submission on 2/5/10. MM, JD, CMK. <br> | |||
* 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. <br> | |||
* Paper submitted 10/6. <br> | |||
<br> | |||
'''‡C. diff Project''' (Cathie, Sonali, Satish Singh, Lisa J., His post doc )<br> | |||
* Sonali to train Lisa on SPE. <br> | |||
* QQ to run test PCR on chip with genomic DNA and Toxin B primers. <br> | |||
<br> | |||
'''‡ Coulter Flu Fraunhofer Project (Lead: Sonali, Team: Sonali, Jessie, Cathie, CMI Folks, Qingqing)''' | |||
* Meeting 9am Monday (every other week) <br> | |||
<br> | |||
'''‡ Agilent Automated Sample Preparation (Lead: Alex)'''<br> | |||
* Paul finishes work on nozzles on Wednesday. Then first testrun and rewriting of software for "HotDog"-Run on Machine. <br> | |||
* First Draft of Paper (Lysis of Yeast Cells) ready. Work ongoing on "Conclusion"-Section of Paper. <br> | |||
<br> | |||
'''‡ COBRA (Lead: Jaephil, Team: Cathie, Jane for virus only, PHO folks)<br>''' | |||
* Metal piece modification for the integration - Parts distored and is begin fixed.<br> | |||
* paper 1: Evap with Sol Gel substrate. Not integrated. MSSA, E coli. <br> | |||
