Pronase from Streptomyces griseus For life science research only. Not for use in diagnostic procedures. Pronase is a mixture of several nonspecific endo- and exoproteases that digest proteins down to single amino acids. Contents Lyophilizate, nonsterile 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. Inhibitors: Complete Protease Inhibitor Cocktail Tablets Optimum pH: 6.0 - 7.5, depending on type of protease activity Specific activity: approximately 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 minute 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 Quality Contaminants: ≤0.002 U DNase/RNase per mg lyophilizate
