Anti-P1PK antibodies enable researchers to detect and measure the P1PK antigen in biological samples. This target is a reported synonym of the A4GALT gene, which encodes alpha 1,4-galactosyltransferase (P blood group). This protein is known to catalyze the transfer of galactose from UDP-alpha-D-galactose to lactosylceramide/beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide(d18:1(4E)) to produce globotriaosylceramide/globoside Gb3Cer (d18:1(4E)). The human version of P1PK has a canonical amino acid length of 353 residues and a protein mass of 40.5 kilodaltons. It is reported to be localized in the Golgi of cells. Other names for this target antigen include A14GALT, A4GALT1, and Gb3S. Indicated applications for P1PK antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
