qPCR – DNased RNA from earlier today

Checked DNased RNA samples from earlier today for the presence of residual gDNA. Used C.gigas BB16 gDNA (from 20110201) diluted to ~7ng/uL as a positive control to match the dilution factor of the RNA that will be used in the reverse transcription reaction (175ng in 25uL = 7ng/uL). All samples were run in duplicate. Master mix calcs are here. Plate layout, cycling params, etc can be found in the qPCR Report (see Results).

Positive control (in Green in qPCR Report) worked perfectly and showed excellent repeatability. The remainder of the samples (in Blue in qPCR Report) and the NTCs (in Red in qPCR Report) were extremely inconsistent with many having one replicate show late amplification, while the other replicate showed no amplification at all. Will have to repeat to get a more definitive assessment of residual gDNA content in these samples.
