We know that the stability of DNA Polymerase remain good at -20 degree celsious. but why it remain liquid even at -20 degree celsious.
Enzyme storage buffer has 50% glycerol (v/v) with freezing temperature -25oC or below (due to additional compounds).
Its due to presence of glycerol which is a cryoprotectant.
Because of thé présence of 50℅ glycerol un thé storage buffer
Is we have any raw sample extract that show positive confirmation in ninhydrin test?
