What is qPCR? Ask a Scientist

Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR). It is primarily used to measure the amount of a specific RNA. This is achieved by monitoring the amplification reaction using fl… WebRT-PCR is commonly used to test for genetic diseases and to characterize gene expression in various tissue types, cell types, and over developmental time courses. This serves as a form of expression profiling, but typically as a candidate approach. RT-PCR is also commonly used to clone cDNAs for further use with other molecular biology ... personal development who am i
