Crude collagenase has been used for many years to isolate a wide variety of cells. The major disadvantage for using recommendations provided by other manufacturer’s or results published in the scientific literature is that cell function or yields are dependent on the unique characteristics of the lot of crude collagenase used in the isolation procedure. The results obtained by one investigator may not be the same as those obtained by another because of the lot to lot variability of crude collagenase. All crude collagenase products are minimally purified, C. histolyticum culture supernatants whose composition reflects the biochemical composition at the end of the fermentation process.
VitaCyte’s low cost, DE Collagenase is designed to overcome many of the limitations of traditional collagenase products (i.e., crude or enriched collagenase) as shown in the table below.
