Anti-PGRN antibodies enable researchers to detect and measure the PGRN antigen in biological samples. This target is a reported synonym of the GRN gene, which encodes granulin precursor. This protein is known to function in the regulation of apoptosis, among other biological roles. The human version of PGRN has a canonical amino acid length of 593 residues and a protein mass of 63.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the lysosomes and is secreted of cells. Other names for this target antigen include CLN11, GEP, and GP88. Western Blot is the most common application for the PGRN antibodies listed below. ELISA, Immunocytochemistry, and Immunohistochemistry are also common applications.
