Pepsin from porcine gastric mucosa
SIGMA/SRE0001 - Suitable for manufacturing of diagnostic kits and reagents, lyophilized powder, ≥3200 units/mg protein
Synonym: Pepsin A; Pepsin from hog stomach
CAS Number: 9001-75-6
EC Number: 232-629-3
MDL Number: MFCD00081840
Product Type: Chemical
Pepsin, a member of the Peptidase A1 family . It exhibits preferential cleavage for hydrophobic, preferably aromatic.
Pepsin is commonly used in the preparation of F(ab)2 fragments from antibodies. In some assays it is preferable to use only the antigen binding (Fab) portion of the antibody.
