Something I notice often in supervising new graduate students is their frustration with the irreproducibility of their biological data. For example, I am asked frequently ‘‘how many biological replicates do I need for qRT-PCR’’? The answer, of course, lies first with the students themselves. They need as many replicates as will persuade them of the validity of their observations. However, for m...
Reverse transcription-PCR (RT-PCR) has traditionally required time-consuming RNA extraction and purification. This report demonstrates that one can completely avoid the RNA extraction step in RT-PCR by basing the comparison of samples on cell number rather than micrograms of total RNA. A new method for lysing cells while preserving RNA is described. RT-PCR is carried out (i) by rapidly freezing...
