Általános leírás
Pepsin is an aspartic endoproteinase isolated from pig gastric mucosa. It is mainly used for the unspecific hydrolysis of proteins and peptides in acidic media. It also provides a limited hydrolysis of native immunoglobulins to yield biologically active fragments.
Egyediség
Aspartic endopeptidase with relatively broad specificity. Preferential cleavage: hydrophobic, preferably aromatic, residues in P1 and P1′ positions.
Alkalmazás
Pepsin has been used for the digestion of liver tissue obtained from rat.
Elkészítési megjegyzés
Working concentration: 0.05 to 0.5 mg/ml
Storage conditions (working solution): A pepsin solution is stable at 2 to 8 °C, at least for one week, at neutral pH and under germfree conditions. Frozen aliquots of the enzyme solution are expected to be more stable.
A stock solution in 10 mM HCl (5-10 mg/ml) should be stable for at least one week at 2 to 8 °C, too. Storage light protected, tightly closed.
A short (2 minutes) incubation at 40 °C has negligible effect on the activity of lyophilized pepsin or pepsin in solution.

The ShK toxin from Stichodactyla helianthus has established the therapeutic potential of sea anemone venom peptides, but many lineage-specific toxin families in Actiniarians remain uncharacterised. One such peptide family, sea anemone 8 (SA8), is present in all five sea anemone superfamilies.
