Thermo Scientific Protease Inhibitor Cocktails are proprietary mixtures of protease inhibitor compounds supplied as 100X liquid stocks for addition to samples to prevent degradation of protein extracts by endogenous proteases that are released during cell lysis. One formulation （Part No. 78410） includes a separate vial of EDTA solution for inhibition of metalloproteases; the other formulation （Part No. 78415） is EDTA-free but includes an undisclosed alternative component for metalloprotease inhibition.
Highlights:
78410 - Protease Inhibitor Cocktail – provides complete protection of proteins from degradation by endogenous proteases that may be released during extraction and purification of proteins from animal and plant tissues, cultured cells, yeast or bacteria. The cocktail inhibits serine and cystine proteases, calpain proteases, and when EDTA is included, metalloproteases. The formulation is proprietary and the product requires thawing before use.
78415 - Protease Inhibitor Cocktail, EDTA-free – unique EDTA-free formulation effectively inhibits most metalloprotease activity and other proteases while allowing optimal action of nuclease activity for removing nucleic acids from samples. Furthermore, the EDTA-free formulation is compatible with purification methods involving immobilized metal chelate affinity chromatography or analysis of extracts by 2-D electrophoresis. The formulation is proprietary and the product requires thawing before use.
Upgrade to Halt Protease Inhibitor Cocktails!
Although we continue to offer the original products described above, we have since developed an improved line of protease inhibitor cocktails: Thermo Scientific Halt Protease Inhibitor Cocktails.
Halt Protease Inhibitor Cocktails provide the following improvements:
Fully disclosed formulations – the identity and concentration of each component of these cocktails are disclosed
No thawing required – cocktails are ready to pipet directly from stable refrigerator storage
Convenient package sizes – choose from four package sizes, including single-use microtubes that keep protease inhibitors fresh and reduce the risk of reagent contamination
