Merck, IM27L-100UG, Anti-Cathepsin B (Ab-1) Mouse mAb (CA10)

General description
Recognizes the ~43 kDa latent and the ~31 kDa active forms of cathepsin B in HepG2 cells.
Anti-Cathepsin B (Ab-1), mouse monoclonal, clone CA10, recognizes the ~43 kDa latent and ~31 kDa active forms of cathepsin B in HepG2 cells. It is validated for WB, IF, and IP.
Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with SP2/O-NS1 plasmacytoma cells. Recognizes the ~43 kDa latent and the ~31 kDa active forms of cathepsin B.
Immunogen
Epitope: within the heavy chain of mature cathepsin B
Human
purified human liver cathepsin B
Application
Immunoblotting (250 ng/ml)
Immunoprecipitation (1 µg/ml)
Immunofluorescence (see comments)
Physical form
Lyophilized from 20 mM ammonium bicabonate buffer, 100 µg BSA (100 µg size) or 20 µg BSA (20 µg size).
Preparation Note
Resuspend the lyophilized antibody with 1 ml sterile PBS. Lyophilized antibodies should be resuspended at 4°C with occasional gentle mixing for at least 2 h. Store at 4°C until reconstituted, then store in aliquots at -20°C or at 4°C with 0.1% azide. Freezing of aliquots is best for long-term storage of reconstituted product. Avoid freeze/thaw cycles.
Analysis Note
Positive Control
Hep G2 cells

This antibody recognizes an epitope on the heavy chain of mature cathepsin B and therefore detects both mature and pro-cathepsin B. Also reported to work for immunofluorescence. Antibody should be titrated for optimal results in individual systems.
