Anti-SP32 antibodies enable researchers to detect and measure the SP32 antigen in biological samples. This target is a reported synonym of the ACRBP gene, which encodes acrosin binding protein. This protein is known to function in spermatid development, among other biological roles. The human version of SP32 has a canonical amino acid length of 543 residues and a protein mass of 61.4 kilodaltons. It is reported to be localized in the cytoplasmic vesicles and is secreted of cells and notably expressed in the testis. Indicated applications for SP32 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, Immunoprecipitation, and Immunohistochemistry.
