Application

La scissione con pepsina può essere utilizzata per produrre frammenti F(ab′)2 di anticorpi. pepsina su www.sigma-aldrich.com/enzymeexplorer.

Biochem/physiol Actions

Scissione preferenziale: residui idrofobi e aromatici nelle posizioni P1 e P1′. Scinde i legami Phe-Val, Gln-His, Glu-Ala, Ala-Leu, Leu-Tyr, Tyr-Leu, Gly-Phe, Phe-Phe e Phe-Tyr nella catena β dell′insulina.

Analysis Note

Il PH ottimale è compreso tra 2 e 4. Attivo in 4 M di urea e 3 M di guanidina HCl. Stabile a 60 °C. La pepsina viene inattivata irreversibilmente in presenza di pH 8,0 - 8,5.

Other Notes

1 U corresponds to the amount of enzyme which increases the absorbance at 280 nm by 0.001 per minute at pH 2.0 and 37°C (Hemoglobin, Cat.No. 51290, as substrate) 15′000 absorbance-U as described above are equivalent to ∼1 Bergmeyer-U. 1 Bergmeyer-U is the amount of enzyme which hydrolyzes 1 μmol Acetyl-L-phenyl-3,5-diiodo-L-tyrosine at pH 2.0 and 37°C
