GENERAL STABILITY
ORGANISM
UNIPROT
LITERATURE
bovine serum albumin, above 1 mg/ml, prevents inactivation at 4°C and 25°C and aggregation
-
considerably less stable in Tris or imidazole buffer than in a magnesium phosphate buffer
-
Mg2+, 20 mM protects to some extent against heat inactivation
-
no stabilization by ATP, CTP, Mn2+, glutamine, cysteine or mercaptoethanol each at 20 mM, 2 mM DTT, 20% glycerol, sucrose, polyethyleneglycol or urea at 1 M
