Pepsin from Porcine Stomach Mucosa
MP BiomedicalsPepsin, an acid protease, contains a proteolytic enzyme. Pepsin contains the "cathepsin" component which has milk curdling activity. It has a broad range of substrate activity and demonstrates an esterase acitivity. It generally attacks peptide bonds. Pepsin is a peptidase used to…

Immobilized Pepsin
G-BiosciencesPepsin is a proteolytic enzyme that is routinely used for the generation of F(ab)2 fragments from immunoglobulin G (IgG). The pepsin has the ability to cleave the heavy chains near the hinge region. One or more of the disulfide bonds that join the heavy chains in the hinge region are…

Pepstatin A
MP BiomedicalsTight-binding, reversible, highly selective inhibitor of acid proteases (aspartyl peptidases), like pepsin, gastricsin, cathepsin E and D, renin, chymosin, bacterial aspartic proteinases and HIV proteases. Does not inhibit thiol proteases, neutral proteases or serine proteases. Widely used as a…

Papain
MP BiomedicalsPapain is a sulfhydryl protease from Carica papaya latex. (A second protease, chymopapain, and a lysozyme have also been isolated from this same source.) Since native crystalline papain is quite unreactive until acted upon by mild reducing agents such as cysteine or cyanide, it may exist as a…

Dispase from Bacillus polymyxa
MP BiomedicalsDipase is an extremely stable microbial metalloprotease suitable for use in cell cultures. Dispase is suitable for tissue disaggregation and subcultivation procedures since it does not damage cell membranes. Dissolve the lyophilized enzyme in sterile water to 5 mg/mL. Further dilution with…

Trypsin from Porcine
MP BiomedicalsThe typical use for this product is in removing adherent cells from a culture surface. The concentration of trypsin necessary to dislodge cells from their substrate is dependent primarily on the cell type and the age of the culture. Trypsins have also been used for the re-suspension of cells during…
