ProtocolforTrichloroaceticAcid(TCA)Precipitation
IntroductionThe efficiency of nucleotide incorporation in DNA/RNA polymerization reactions (e.g. transcription, reverse transcription, and DNA replication) can be determined by trichloroacetic acid (TCA) precipitation. TCA precipitates nucleic acid polymers longer than ~20 nucleotides and can therefore be used to separate radiolabeled nucleotides incorporated into nucleic acid from unincorporated label.The following ......阅读全文
