产品详细信息Description: Cathepsin L is a lysosomal cysteine proteinase consisting of a heavy chain of about 25 kDa and a light chain of about 5 kDa derived proteolytically from the same precursor. Cathepsin L has been shown to be produced by many different cell types. Since cathepsin L is capable of degrading protein constituents of the extracellular matrix it is assumed to play a crucial role in tumor progression and metastasis and a number of other disorders where the destruction of the extracellular matrix is the major cause of disease (e.g. rheumatoid arthritis, neurodegeneration).Applications Tested: ELISA, Immunohistochemistry (Frozen), Western Blotting.靶标信息The protein encoded by this gene is a lysosomal cysteine proteinase that plays a major role in intracellular protein catabolism. Its substrates include collagen and elastin, as well as alpha-1 protease inhibitor, a major controlling element of neutrophil elastase activity. The encoded protein has been implicated in several pathologic processes, including myofibril necrosis in myopathies and in myocardial ischemia, and in the renal tubular response to proteinuria. This protein, which is a memberof the peptidase C1 family, is a dimer composed of disulfide-linked heavy and light chains, both produced from a single protein precursor. At least two transcript variants encoding the same protein have been found for this gene.

数据

Cathepsin L Antibody (BMS1032) in ICCImmunofluorescence analysis of Cathepsin L was performed using 70% confluent log phase A549 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with Cathepsin L Monoclonal Antibody (33-2), eBioscience™ (Product # BMS1032) at 5ug/ml in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Goat anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32723), (1:2000), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification. Cathepsin L Antibody (BMS1032) in WBKnockdown of Cathepsin L was achieved by transfecting A549 with Cathepsin L specific siRNAs (Silencer® select Product # S223364, S3754). Western blot analysis (Fig. a) was performed using Whole cell extracts from the Cathepsin L knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with Cathepsin L Monoclonal Antibody (33-2), eBioscience™ (Product # BMS1032, 1 ug/ml ) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution). Densitometric analysis of all three expected bands of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to Cathepsin L.
