‡ Announcements
† HDA (Lead: Jaephil, Team:Sonali)
† SPE Column Optimization for RNA. (Lead: Sonali, Team: Hussam, Jessie, Brendan)
- Fourth design was made and tested with PCR reagent(Flu assay).ATCC RNA from Jessie was used. - it works! - patient sample will be tested next.
- primer for toxin A. - product size and concentration was verified by bio-analyzer. - on chip PCR was optimized with higher BSA concentration(0.02%).It did not work. - 40 cycle chip and 0.03% (BSA concentration) will be tested. - primer for toxin B. -Both two pairs of primers for toxin B works, with a ct value around 13. -on chip PCR has been done, the result has not been tested by bio-analyzer.
