SpecificityThe specificity of this antibody has been confirmed by WB and IHC against the antigen. Human; mouse; rat;
Species ReactivityHuman, Mouse, Rat
Immunogen DescriptionProcathepsin L isolated from human lung cancer cell line EPLC32M1. The epitope is within the sequence GYGFEST (265-271 in procathepsin L and 169-175 in the mature cathepsin L molecule).
Application DetailsImmunohistochemistry (IHC) and Western Blotting (WB). A concentration of 2.0 µg/mL is recommended for WB. A concentration of 4.0 µg/mL is recommended to detect cathepsin L in formalin/acetone fixed tissues. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Reconstitution InstructionsSpin vial briefly before opening. Reconstitute in 1 mL of sterile-filtered PBS (pH 7.4) to achieve an antibody concentration of 100 µg/mL. Centrifuge to remove any insoluble material.
Storage InstructionsAt least 12 months after purchase at 2-8°C (lyophilized formulations). After reconstitution, aliquot and store at -20°C for a higher stability. Avoid freeze-thaw cycles.

Expiration Date12 months after date of receipt (unopened vial).
Scientific BackgroundCathepsin L is a cystein protease. It is important for the overall degradation of proteins in lysosomes. Cathepsin L substrates include collagen, elastin and alpha 1 protease inhibitor. The protein is initially expressed as procathepsin L (42 kDa) and is proteolytically processed into 30 kDa and 21 kDa forms. This antibody recognises both precursor and mature forms.
