Protease from Streptomyces griseus ,P8811 - powder, BioReagent, suitable for mouse embryo cell culture, ≥3.5 units/mg solid
别名: Actinase E, Pronase E
CAS号: 9036-06-0
product line BioReagent form powder total impurities starch, essentially free suitability suitable for mouse embryo cell culture storage temp. −20°C
产品描述如下:
Application
Protease is typically used in nucleic acid isolation procedures in incubations of 0.5-3.0 hours supplemented with 0.2% sodium dodecyl sulfate and 10 mM EDTA.
Other Notes
An unusually non-specific protease.
Preparation Note
Collected from culture broth of S. griseus and purified by successive column procedures.
Quality
Contains approximay 25% calcium acetate.
Specificity
A mixture of at least three proteolytic activities including an extracellular serine protease. In general, serine proteases display a wide range of substrate specificities, which are believed to be mediated by an active site composed of one Asp, one His, and a Ser residue in the molecule. This enzyme prefers to hydrolyze peptide bonds on the carboxyl side of glutamic or aspartic acid.
Unit Definition
One unit will hydrolyze casein to produce color equivalent to 1.0 μmole (181 μg) of tyrosine per min at pH 7.5 at 37 °C (color by Folin-Ciocalteu reagent).
Physical properties
Compley inactivated by heating above 80 °C for 15-20 minutes.
