We have developed an exceptionally sensitive assay for the proteases calpain I and II. The Calpain-Glo™ Protease Assay is a rapid, homogeneous assay with a luminescent signal that is proportional to the amount of calpain present in the sample. The Calpain-Glo™ Assay uses a recombinant thermostable luciferase, Ultra-Glo™ Luciferase, that dramatically improves sensitivity and detects calpain over a broad range of activity.
