PronaseE 链霉蛋白酶E

 

PronaseE   链霉蛋白酶E                                             
Application :                                                                
Total degradation of proteins during the isolation of DNA and RNA; (it is not necessary to let pronase self-digest prior to use). Total hydrolysis of proteins in research and for technical purposes. Tissue dissociation in conjunction with collagenase and trypsin. Production of glycopeptides from purified glycoproteins.                                                        
Product Description :
Inhibitors: Complete Protease Inhibitor Cocktail Tablets                  
Optimum pH: 6.0 - 7.5, depending on type of protease activity                        
Specific activity: approx. 7,000 U/g lyophilizate at 40°C with casein as the substrate, pH 7.5. One unit is the enzyme activity that liberates folin-positive amino acids and peptides, corresponding to 1 µmol Tyr in 1 min under assay conditions.                                    
Specificity: Mixture of several nonspecific endo- and exoproteases that generally digest proteins down to single amino acids. Resolves carboxylic acids and alcohols.                            
Working concentration: 0.5 - 2 mg/ml
