Application
Casein fluorescein isothiocyanate from bovine milk has been used:
- in accessing zona pellucida (ZP) and perivitelline space (PVS) to evaluate changes induced by protease treatment[1]
- to make a reference line in immunochromatographic devices[2]
- in running gel for the documentation of proteinases[3]
highly sensitive protease substrate
Biochem/physiol Actions
Casein fluorescein isothiocyanate is mainly used as a substrate in estimating the protease activity of psychrotrophic bacteria. It is also used as a substrate for determining the activity of bacteria in milk.[4]

Endosymbiosis has driven major molecular and cellular innovations. Plasmodium spp. parasites that cause malaria contain an essential, non-photosynthetic plastid-the apicoplast-which originated from a secondary (eukaryote-eukaryote) endosymbiosis.
