General description
Anti-Cathepsin L antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the hybridoma CPL33/1 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with human procathepsin L.
Monoclonal Anti-Cathepsin L (mouse IgG1 isotype) is derived from the hybridoma CPL33/1 produced by the fusion of mouse myeloma cells (P3X63Ag8.653) and splenocytes from BALB/c mice immunized with human procathepsin L.
Specificity
The antibody recognizes the native and denaturated forms of the protein and does not cross react with human cathepsin V. Monoclonal Anti-Cathepsin L specifically recognizes human cathepsin L (∼ 25 kDa) and procathepsin L (∼ 42 kDa). Anti-Cathepsin L antibody epitope resides within amino acids of human cathepsin L (FYKE).
Immunogen
human procathepsin L. The antibody epitope resides within amino acids 258-261 of human cathepsin L (FYKE).
Application
Anti-Cathepsin L antibody has been used for immunoblotting.
Monoclonal Anti-Cathepsin L antibody produced in mouse is suitable for:
- immunohistochemistry
- indirect ELISA
- western blot : 0.1-0.2 μg/mL using total cell extracts of A549 cells
Biochem/physiol Actions
Cathepsins are lysosomal proteases that play an important role in the intracellular degradation of exogenous and endogenous proteins, activation of enzyme precursors, and tumor invasion and metastasis.
Inhibition of the enzyme or the proenzyme by low molecular weight inhibitors or by specific antibodies led to a suppression of the invasive capabilities of malignant cells, or a decline in their ability to form tumors in experimental in vivo and in vitro models.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
