Anti-Sk521 antibodies enable researchers to detect and measure the Sk521 antigen in biological samples. This target is a reported synonym of the STKLD1 gene, which encodes serine/threonine kinase like domain containing 1. This protein is known to function in protein phosphorylation, among other biological roles. The human version of Sk521 has a canonical amino acid length of 680 residues and a protein mass of 75.7 kilodaltons, although 3 isoforms have been identified. Sk521 is a member of the Ser/Thr protein kinase protein family. Indicated applications for Sk521 antibodies listed below include ELISA, Western Blot, and Immunofluorescence.
