Anti-HDJ2 antibodies enable researchers to detect and measure the HDJ2 antigen in biological samples. This target is a reported synonym of the DNAJA1 gene, which encodes DnaJ heat shock protein family (Hsp40) member A1. This protein is known to function in the regulation of apoptosis and protein folding, among other biological roles. The human version of HDJ2 has a canonical amino acid length of 397 residues and a protein mass of 44.9 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane, nucleus, mitochondria, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include DJ-2 and DjA1. Western Blot is the most common application for the HDJ2 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
