Applications

Pepsin is commonly used in the preparation of Fab fragments from antibodies. Pepsin, from porcine gastric mucosa, has been used to hydrolyze dry cervical samples in mice. has been used in the digestion of crude wheat gliadin. It has been used along with other enzymes to demonstrate the effects of fixation and enzymatic digestion in immunohistochemical assays, using paraffin embedded tissue. It has been used for digestion (before using immunoperoxidase techniques) to reduce non-specific background staining in sections of bronchial tissues. The enzyme has also been used in the preparation of F(ab)2 fragment from IgG.

Notes

Minimum 2,500 units/mg. One unit increases absorbance at 280nm by 0.001 per minute at 37 C and pH 2.0, measured as TCA soluble products from denatured hemoglobin
