Anti-SIK antibodies enable researchers to detect and measure the SIK antigen in biological samples. This protein is known to function in intracellular signal transduction and protein phosphorylation, among other biological roles. The human version of SIK has a canonical amino acid length of 783 residues and a protein mass of 84.9 kilodaltons. SIK is a member of the CAMK Ser/Thr protein kinase protein family. ELISA, Western Blot, and Immunohistochemistry are common applications for SIK antibodies.
