Pierce Protease Inhibitor The microtablets prevent proteolytic degradation of proteins by inhibiting serine, cysteine, aspartic and aminopeptidase enzymes commonly present in cell lysate samples. This tablet contains AEBSF, aprotinin, statin, E-64, leupeptin and gastropin A. Stable for up to 12 months when stored at 4°C, each microtablet is large enough to dissolve into a 10 mL solution, making it suitable for reagent preparation prior to protein extraction from tissues and cultured cells.

Proteases constitute a large class of enzymes, including endo- and exopeptidases, which catalyze the hydrolytic breakdown of proteins into peptides or amino acids. Proteases are present within cellular compartments, but are released upon cell lysis, leading to the degradation of valuable proteins. Therefore, it is often necessary to add a variety of known compounds to inactivate or inhibit proteases in cell lysis buffers or cell extracts.

To use Pierce Protease Inhibitor Mini Tablets, simply dissolve 1 tablet in 10 mL of buffer or lysate. The protease inhibitor formulation is compatible with most detergent-based cell lysis reagents, including Pierce Cell Lysis Buffer. Pierce Protease Inhibitor Mini Tablets do not contain phosphatase inhibitors. If necessary, a phosphatase inhibitor (such as Pierce Phosphatase Inhibitor Mini Tablets) can be added along with the protease inhibitor tablets.
