Anti-SLY antibodies enable researchers to detect and measure the SLY antigen in biological samples. This target is a reported synonym of the SASH3 gene, which encodes SAM and SH3 domain containing 3. This protein is known to function in T cell differentiation, among other biological roles. The human version of SLY has a canonical amino acid length of 380 residues and a protein mass of 41.6 kilodaltons. It is reported to be notably expressed in many tissues, such as the cerebellum, tonsil, and appendix. Other names for this target antigen include 753P9, CXorf9, and HACS2.
