Thermo Scientific Halt Protease Inhibitor Cocktails are ready-to-use concentrated stock solutions of protease inhibitors for addition to samples to prevent proteolytic degradation during cell lysis and protein extraction.
Halt Protease Inhibitor Cocktails are 100X solutions containing optimized concentrations of six broad-spectrum protease inhibitors stabilized in high-quality dimethylsulfoxide （DMSO）. The cocktails effectively inhibit serine-proteases, cysteine-proteases, aspartic acid-proteases and aminopeptidases that are typically present in cellular lysate samples. The identity and concentration of each component is fully disclosed, leaving no uncertainties about variables and compatibility with experiments. Regular and EDTA-free formulations provide for inhibition of metalloproteases and compatibility with 2D electrophoresis, respectively. The stable, concentrated liquid cocktails are easy to use, and the several different package sizes make Halt Protease Inhibitor Cocktails exceptionally convenient for either small-scale or large-scale uses.
Highlights:
Convenient – the refrigerator-stable, 100X liquid format is more effective and easier to use than individual inhibitors or other formats; just pipette exactly the amount you need
No proprietary ingredients – fully disclosed formulation contains AEBSF, aprotinin, bestatin, E-64, leupeptin and pepstatin A in DMSO
Multiple package sizes – choose among several package sizes, including single-use microtubes that keep protease inhibitors fresh and reduce the risk of reagent contamination
Two popular formulations – regular formulation includes a separate vial of EDTA solution for optional metalloprotease inhibition; EDTA-free formulation ensures compatibility with isoelectric focusing
Lysis buffer compatible – use with Thermo Scientific Pierce Cell Lysis Buffers or nearly any other commercial or homemade detergent-based lysis reagent
Applications:
Protection of intact, active cellular proteins from degradation by endogenous proteases
Inhibition of protease activity from lysates produced by a variety of methods including Thermo Scientific Pierce Cell Lysis Reagents, other commercially formulated cell or tissue lysis products, sonication, French press, blender homogenization or repetitive freeze/thaw cycling
Screening of extracts for proteolytic activity
The study of proteolysis in the regulation of cellular processes
Product Details:
Halt Protease Inhibitor Cocktails are easy to use. Simply add 10µL of concentrated cocktail per 1mL of lysis buffer to ensure complete protection of the resulting protein extract. Both EDTA and EDTA-free formulations of Halt Protease Inhibitor Cocktails are available in single-use format （24 x 100µL microtubes） and 1mL, 5mL and 10mL package sizes. The single-use format is ideal for small-scale cell lysis experiments, where each 100µL vial provides just what is needed for a 10mL sample and there is no risk of contaminating or degrading remaining aliquots of cocktail. Each microtube in the strip is heat-sealed with a foil that can be easily punctured by a pipette tip for trouble-free access to a precise amount of Halt Protease Inhibitor Cocktail needed for each experiment.
