Due to craziness seen in melting curves, fluorescence, and empty wells from the previous run, will compare SYTO vs. SYBR with select MV cDNAs. Additionally, acquired some qPCR strip caps to use instead of the ABI film. Used Cv_18s_F/R primers. qPCR set up/plate layout is here.
Results: Both seem to work fine. H2O fluorescence is weird, but doesn’t come up in the melting curves. Strategene SYBR provides a brighter signal, but results in a higher melting temp than the SYTO.
Results: DNase treatment worked on all but the following samples: B23, B14, A21. However, these three samples were slightly below the initial, background fluorescence in each sample. The Turbo kit test indicates that all three kits are working perfectly and all can/should be used with confidence for treating samples.
Samples 3326: B23, A25, A22, B14, A21, A10 B22 came up positive for gDNA still. These were retreated according to Ambion protocol with a brand new Turbo DNA-free DNase kit. Additionally, I tested all three existing kits by “spiking” 19uL of H2O with 1uL (~200ng) of gigas gDNA; one tube for each kit and an untreated sample. Will qPCR to see if gDNA removal was successful.
