Splet01. jan. 2024 · Published 1 January 2024 Biology Biology Methods & Protocols Abstract We describe an ultra-rapid and sensitive method to quantify gene expression levels in cultured cells. The procedure is based on reverse-transcription quantitative PCR (RT-qPCR) directly from cells, without RNA extraction and without an isothermal reverse-transcription step. SpletThe acid-guanidinium thiocyanate-phenol-chloroform method for RNA extraction and proteinase K digestion-phenol-chloroform method for DNA extraction from serum samples are used widely for PCR assays (1,2), but usually at least 3 h are needed for this step.
