Anti-TSK antibodies enable researchers to detect and measure the TSK antigen in biological samples. This target is a reported synonym of the TSKU gene, which encodes tsukushi, small leucine rich proteoglycan. This protein is known to function in eye development and cholesterol metabolism and homeostasis, among other biological roles. The human version of TSK has a canonical amino acid length of 353 residues and a protein mass of 37.8 kilodaltons. It is reported to be a secreted protein that is widely expressed in many tissue types. Other names for this target antigen include E2IG4 and LRRC54. Indicated applications for TSK antibodies listed below include ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry.
