Collagenase NB 7D Gentle Grade-Gentle to Cells

For Dendritic Cells and Other Sensitive Tumor Cells

Collagenase NB 7D Gentle Grade is suitable for isolation of a broad variety of cells. Moreover, it can be used especially where sensitive conditions are favored, such as during isolation of dendritic and tumor cells from human or animal tissues. To meet these requirements, Collagenase NB 7D Gentle Grade combines the benefits of slightly higher collagenase activity with low tryptic activities ideal to preserve cell-surface proteins.

If you are dealing with less efficient cell isolation results, a product with higher tryptic activities like Collagenase NB 4G Proved Grade might be more suitable. However, in case of poor cell viability, try a product with even less tryptic activities like Collagenase NB 1 Premium Grade.
