Pepsin NB Technical Grade from porcine gastric mucosa
granulate, vacuum dried
(Pepsin A) EC 3.4.23.1 • Mr ca. 35 000 • CAS [9001-75-6]
Contains pepsin isolated from porcine gastric mucosa. Veterinary
certificate available (ingredient porcine gastric mucosa). Tested according
to Ph. Eur. Stabilized with sodium benzoate. For laboratory use only. Protease
activity ≥ 0.65 Ph. Eur.-E./mg. Sodium benzoate 0.35 - 0.45 % (w/w). For
the degradation of proteins or production of F(ab')2 fragments of
antibodies. Pepsin has a particularly broad cleavage specificity, although the
enzyme preferentially hydrolyses those peptide linkages which involve
hydrophobic, especially aromatic amino acid residues.
Unit definition: according to Ph. Eur. (1 Ph. Eur.-E./mg is equal to
1 Ph. Eur.-E./mg Pepsin reference standard (BRS); activity is measured in
terms of non-TCA-precipitable peptides released from hemoglobin per minute at
25 °C, pH 1.6).
