Description

Pinguinain CAS NO 37288-97-4 is a proteolytic enzyme derived from pineapple (*Ananas comosus*), specifically from the fruit and stem. This compound is valued for its ability to cleave peptide bonds, making it a critical biochemical tool for research and industrial applications. It is primarily utilized in the life sciences for protein analysis, in the food industry for processing, and in the development of cosmetic and therapeutic formulations.

Application

• Biochemical Research: Used as a protease in protein sequencing, peptide mapping, and the study of protein structure-function relationships.
• Pharmaceutical Development: Employed in the research and production of biopharmaceuticals, including the digestion of antibodies for analysis.
• Food & Beverage Processing: Acts as a natural meat tenderizer and is used in the clarification of beverages.
• Cosmetic Formulations: Incorporated into exfoliating and skin-renewal products for its keratolytic properties.
• Diagnostic Kits: Serves as a key reagent in enzymatic assay kits and diagnostic tests.
• Cell Culture & Tissue Engineering: Utilized for cell dissociation and the preparation of biological tissues.
