Under what conditions can Product P5147, Protease from Streptomyces griseus, be used to digest protein?
1 回答-
For DNA isolation, Pronase E is usually prepared as a stock solution, and prior to storage at -20°C, the solution is first heated to 56°C for about 15 minutes, then incubated at 37°C for 1 hour. This encourages self-digestion, to eliminate DNAse and RNAse contamination. The enzyme is added to a DNA sample (in the presence of 0.5-1%(w/v) SDS to disrupt DNA protein interactions) typically at 250-500 μg protein/mL, then incubated at 37°C for 1-4 hours. For protein hydrolysis, dissolve about 0.2 μmol of protein in 0.2 mL of 50 mM ammonium bicarbonate buffer at pH 8 (or phosphate buffer pH 7). Add Pronase to 1% (w/w) and incubate at 37°C for 24 hours. It may be necessary to add aminopeptidase M at 4% (w/w) and incubate at 37°C for another 18 hours.

Is Product P5147, Protease from Streptomyces griseus, also described as "Pronase"?
1 回答-
"Pronase E" is the name given to a group of proteolytic enzymes produced by Streptomyces griseus K-1. At least 10 proteases are in the mixture, five serine-type proteases, two zinc endopeptidases, two zinc leucine aminopeptidases, and one zinc carboxypeptidase.

Does Product P5147, Protease from Streptomyces griseus, contain calcium acetate?
1 回答-
This product contains calcium acetate buffer salt. The amount of calcium acetate present will vary for each lot number and has been observed to range from 2 - 30% (w/w).

How should Product P5147, Protease from Streptomyces griseus, be reconstituted and how should a stock solution be prepared?
1 回答-
This product can be dissolved in 0.01 M sodium acetate with 0.005 M calcium acetate at pH 7.5 at 37°C; at 0.2 mg/mL, this yields a clear solution which ranges from colorless to light tan. Calcium ion is recommended for protection from autolysis. The activity of a dilute enzyme solution containing 0.01 to 0.1 M calcium ion was stable over 24 hours at neutral pH at 2-8°C. Pronase E is stable at 4°C for at least six months. Stock solutions of 5 to 20 mg/mL in water are usually stored at -20°C.
