Neutral Protease AF GMP Grade - Animal Free

For Cell Isolation from Pancreas, Adipose Tissue and Tumors

Neutral Protease AF GMP Grade is derived from C.histolyticum using a production process completely free of any animal-based components. Thus, any risk of transmission of potential animal-derived pathogens is excluded. This purified metalloprotease is suitable for the dissociation of tissue in clinical applications. For especially gentle cell isolation it is recommended to use Neutral Protease AF GMP Grade in combination with highly purified Collagenase AF-1 GMP Grade. Here, it has been shown to be highly effective for the isolation of islets of Langerhans from human pancreas intended for transplantation and stromal vascular fraction (SVF) from adipose tissue and tumor cells.
