The Magic Red™ Cathepsin L kit uses a quick and easy method to analyze intracellular Cathepsin L protease activity in whole living cells.
- Reagents in the Kit
- Magic Red™ MR-(FR)2 Reagent - lyophilized
Hoechst 33342 Stain, 1 mL
Acridine orange (AO), 0.5 mL
- Test Principle
- Cathepsin Magic Red™ kits measure Cathepsin L protease activity by detecting active cathepsins in whole, living cells. These kits do not work by using antibodies or as an ELISA. Instead, their methodology is based on a cell-permeable and non-cytotoxic reagent which is cleaved in the presence of cathepsins to produce a fluorescent product.
The Magic Red™ reagent contains a Cathepsin L target sequence peptide (FR)2 linked to a red (Cresyl Violet) fluorescent probe.
The Cathepsin Magic Red™ kits are suitable for cells in suspension and adherent cells from many species including mammalian, insect and yeast. Different cell types, e.g. Jurkat, HL-60, THP-1, fibroblasts, UMUC-3, MCF-7 and U937 cells have also been successfully studied with these kits.
This kit can be used in fluorescence microscopy or with fluorescence plate readers using black microtitre plates.
- Store the unopened kit (and each unopened component) at +4oC until the expiration date.
Protect the MR-(FR)2 reagent from light at all times.
Once reconstituted, the 260X MR-(FR)2 stock should be stored at -20°C protected from light.
- Guaranteed until date of expiry. Please see product label.
