MtoZ Biolabs Proteinase K is a ready-to-use, sterile serine protease solution formulated for protein digestion during nucleic acid extraction from biopharmaceutical samples. Certified free of DNase and RNase contamination, it effectively degrades host cell proteins, mycoplasma-associated proteins, and mycobacterial cell wall components, enabling efficient release and recovery of target DNA for downstream PCR-based detection.
Product Overview
In DNA extraction workflows for biopharmaceutical quality control, incomplete protein removal is one of the most common sources of assay failure and result variability:
1. Residual host cell proteins and membrane components can physically shield DNA from extraction reagents, reducing nucleic acid yield and undermining detection sensitivity.
2. Nuclease activity from contaminated digestion reagents can degrade template DNA during the protein digestion step, leading to false-negative results in residual DNA quantification.
3. Insufficient digestion of mycobacterial cell walls or mycoplasma membranes can result in incomplete DNA release, causing underestimation of contamination levels in safety testing.
4. Variability in enzyme activity between reagent lots can introduce inconsistency across extraction batches, compromising inter-run reproducibility and regulatory data integrity.
