Anti-Cathepsin L2 antibodies enable researchers to detect and measure the Cathepsin L2 antigen in biological samples. This target is a reported synonym of the CTSV gene, which encodes cathepsin V. This protein is known to function in immune response pathways and the regulation of apoptosis, among other biological roles. The human version of Cathepsin L2 has a canonical amino acid length of 334 residues and a protein mass of 37.3 kilodaltons. It is reported to be localized in the lysosomes of cells. Other names for this target antigen include CATL2, CTSL2, and CTSU. Western Blot is the most common application for the Cathepsin L2 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
