General description

Coelenterazine hcp is a semisynthetic analog of coelenterazine.

Application

Coelenterazine hcp has been used:
  • as a component of coelenterazine reagent in the reporter assay
  • in the purification of Renilla luciferase-labeled Annexin V
  • in evaluating the activity of aequorin in Escherichia coli

Biochem/physiol Actions

Coelenterazine hcp has 190 times higher luminescence intensity than native coelenterazine and a faster response time than native coelenterazine.
