产品介绍:

应用
Cresol red is commonly used with lead acetate for the detection of urease after PAGE. It is also used as an indicator with the following transition intervals: pH 1.8 (orange) to pH 2.0 (yellow); pH 7.0 (yellow) to pH 8.8 (violet). Cresol Red is used as a tracking dye in DNA, RNA (agarose) and protein (polyacrylamide) electrophoresis. In agarose, Cresol Red runs with an apparent molecular size of approx. 125 bp DNA. Cresol Red does not inhibit Taq polymerase.
