	Pepsin - LoveToKnow 1911
		PEPSIN, an enzyme or ferment obtained by drying the mucous lining of the fresh and healthy stomach of a pig, sheep or calf.
		Pepsin is used to help gastric digestion in old people and in those in whom there is a deficient secretion of the gastric juice.
		Pepsin digests the albumens but is useless in the digestion of fats or carbohydrates.

	pepsin - Encyclopedia.com
		Pepsin is one of three principal protein-degrading, or proteolytic, enzymes in the digestive system, the other two being chymotrypsin and trypsin.
		Pepsin is synthesized in an inactive form by the stomach lining; hydrochloric acid, also produced by the gastric mucosa, is necessary to convert the inactive enzyme and to maintain the optimum acidity (p H 1-3) for pepsin function.
		Pepsin and other proteolytic enzymes are used in the laboratory analysis of various proteins; pepsin is also used in the preparation of cheese and other protein-containing foods.

	Immobilized Pepsin
		Pepsin is an ideal protease for nonspecific protein digestion and for preparing F(ab’)2 fragments from antibodies.
		Pepsin is a nonspecific acidic endopeptidase produced in an inactive precursor form (pepsinogen) in the mucosal lining of the stomach of vertebrates.
		Immobilized pepsin can be substituted for free pepsin in any application, and is advantageous because it virtually eliminates autolysis, eliminates contamination of a sample with the protease and allows control of the digestion by removing the pepsin.

	Epitope Retrieval Protocol - Pepsin Method
		Description: Formalin or other aldehyde fixation forms protein cross-links that mask the antigenic sites in tissue specimens, thereby giving weak or false negative staining for immunohistochemical detection of certain proteins.
		The pepsin based solution is designed to break the protein cross-links, therefore unmask the antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, thus enhancing staining intensity of antibodies.
		Cover sections with pepsin working solution and incubate for 10-20 minutes at 37 °C in humidified chamber (optimal incubation time may vary depending on tissue type and degree of fixation, and should be determined by user).

		Just as the pepsin digestibility test can be seen as a refinement of the crude protein test, the non-standard dilutions of pepsin digestibility can be viewed as refinements of the pepsin digestibility test.
		The pepsin enzyme is there to promote digestibility, so the less of it present, the lower the digestibility reading.
		There seems to be general consensus that the utility of the test is improved by tailoring the pepsin concentration to the nature of the material.
