Alkalineagarosegelelectrophoresis
Alkaline agarose gel electrophoresis (Sambrook et al., 1989)Alkaline agarose gels can be used to determine the size and quality of first and second strand cDNA synthesis by reverse transciptase.You will need:Alkaline loading buffer (300mM NaOH, 6mM EDTA, 18% Ficoll 400, 0.15% bromocresol green, 0.25% xylene cyanol FF)10 x Alkaline agarose electrophoresis buffer (500mM NaOH, 10mM EDTA, pH 8.0, made fresh for each use)......阅读全文
