Description
OverviewA highly sensitive and selective fluorogenic assay for the detection of Cathepsin L from human and mouse samples. Cathepsin L is detected with the fluorogenic substrate Z-Phe-Arg-AMC (Exc. max: 360 nm; Emi. max: 460 nm). Interference from Cathepsin B is eliminated by the incorporation of CA 074, a specific cathepsin B inhibitor. This kit is also useful for screening cathepsin L inhibitors.
Catalogue NumberCBA023
Brand Family Calbiochem®
Application Data
Calibration curve generated using the AMC Calibration Standard included in the InnoZyme™ Cathepsin L Activity Kit. The assay was carried out as specified in the Cathepsin L Inhibitor Screening protocol.
Materials Required but Not Delivered Purified Cathepsin L (for inhibitor screening only)
Protein assay (for biological samples)
Precision pipettors or multi-channel precision pipettor; use only pipettors that are carefully calibrated to their target volume
37°C incubator/shaker
Microplate reader capable of measuring fluorescence at wavelengths 360-380 nm for excitation and 440-460 nm for emission
Ice bucket
