Anti-HSP40 antibodies enable researchers to detect and measure the HSP40 antigen in biological samples. This target is a reported synonym of the DNAJB1 gene, which encodes DnaJ heat shock protein family (Hsp40) member B1. This protein is known to function in brain development and the regulation of transcription, among other biological roles. The human version of HSP40 has a canonical amino acid length of 340 residues and a protein mass of 38 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Indicated applications for HSP40 antibodies listed below include ELISA.
