My Experiments 
Roche™ Pronase is a high-quality non-specific protease mixture derived from Streptomyces griseus, designed for comprehensive protein degradation in molecular biology and biochemical applications.
With its broad substrate specificity, Pronase efficiently hydrolyzes proteins into amino acids and small peptides, making it ideal for DNA/RNA extraction, tissue dissociation, and protein analysis workflows.
Supplied as a lyophilized powder, this enzyme provides excellent stability, high activity, and reproducible performance for demanding laboratory applications.
Key Features and Benefits
Broad Proteolytic Activity
Pronase exhibits wide substrate specificity, enabling the breakdown of virtually all proteins into their constituent amino acids.
Optimized for Molecular Biology Applications
Highly suitable for DNA and RNA isolation workflows, including plasmid and phage DNA extraction.
High Enzymatic Activity
Approximately 1270 PU/mg (casein substrate at 40°C, pH 7.5), ensuring efficient and rapid protein digestion.
Minimal Nuclease Contamination
Very low DNase and RNase activity (<0.002 U/mg), preserving nucleic acid integrity during extraction.
Enhanced Stability with Calcium Ions
Formulated with calcium acetate to improve enzyme stability and resistance to heat inactivation.
Flexible Usage Across Applications
Effective in cell culture, histochemistry, glycoprotein processing, and tissue dissociation workflows.
Applications
- DNA and RNA extraction (plasmid, genomic, and phage DNA)
- Protein digestion and hydrolysis
- Tissue dissociation in cell culture (with collagenase/trypsin)
- Histochemistry and cellular analysis
- Glycopeptide production from glycoproteins
- Zebrafish embryo dechorionation
- Protein removal in nucleic acid purification workflows
