Collagenase NB 1 GMP Grade- For Islet Isolation
For Pancreatic Cell Isolation and other GMP Applications
Collagenase NB 1 GMP Grade is a highly purified collagenase grade. This product is used for isolation of sensitive cells and guarantees high yields and viability. In combination with Neutral Protease NB GMP Grade, Collagenase NB 1 GMP Grade is especially applicable to isolation of pancreatic islets of Langerhans. Collagenase NB 1 GMP Grade is recommended for applications like tissue engineering and transplantation into humans which have to meet GMP requirements.
