You can also contact VitaCyte’s technical service team that has a significant amount of experience working with customers to have them transition switching enzymes in their cell isolation procedures. The advantage of using VitaCyte’s product in place of traditional collagenase products is that once product and dose of enzyme used in an isolation is determined, there is no need to perform lot qualification again. VitaCyte’s products are consistently manufactures and the neutral protease activity, the key variable in any enzyme formulation, is tightly controlled to minimize variability between lots.
