Pubtime:2024-04-16
View volume:163

The commonly used concentration of trypsin EDTA is 0.05% trypsin 0.53 mM EDTA Na4. After the first bottle opening, a small amount should be immediately divided into sterile test tubes and stored at -20 ℃ to avoid repeated freezing and thawing, which can reduce the activity of trypsin and reduce the chance of contamination.
