Worthington currently offers Cell Isolation Systems which are kits containing enzymes and other required reagents for performing tissue dissociations without having to purchase individual packages of one or more enzymes and pretesting various lots of some enzymes. Some are designed for working with specific tissues, and one kit is a general purpose procedure development system. In all cases, the enzymes which are included in the kits are regular Worthington products which can be purchased independently.

Below are descriptions of each of the current kits.

• Neonatal Cardiomyocyte Isolation System (NCIS)
• Papain Dissociation System (PDS)
• Cell Isolation Optimizing System (CIT)
