Anti-PLS antibodies enable researchers to detect and measure the PLS antigen in biological samples. This target is a reported synonym of the CTSC gene, which encodes cathepsin C. This protein is known to function in pathways of aging and immune response pathways, among other biological roles. The human version of PLS has a canonical amino acid length of 463 residues and a protein mass of 51.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the lysosomes of cells and widely expressed in many tissue types. Other names for this target antigen include CPPI, DPP-I, and DPP1. Western Blot is a widely used application for the PLS antibodies listed below. In addition, ELISA is also a common application.
