Product Description

Pepsin 660 U/ml liquid belongs to the Pepsin series of Costantino industrial enzymes production. It is available in a solution formulation. Pepsin is one of the most important protease naturally present in gastric juice; it is able to cleave peptidic bonds at different sites, depending on the nature of the protease. Pepsin, that is prepared commercially from swine gastric mucosa, is most active in acid environments between 37°C and 42°C.

Pepsin 660 U/ml liquid is the result of the skill of Costantino in the selection and optimization of the best supply chain in combination with a stable and capable process. High quality gastric mucosa is firstly hydrolyzed to release enzymes, then filtered and concentrated without affecting enzymatic activity. The product is finally diluted to obtain the best purity and the required proteolytic activity, claimed as 660 U/ml. As many Costantino products, customization is available for eventual fine-tuning of the claimed proteolytic activity to fit the customers optimal needs.
