Anti-FEEL2 antibodies enable researchers to detect and measure the FEEL2 antigen in biological samples. This target is a reported synonym of the STAB2 gene, which encodes stabilin 2. This protein is known to function in angiogenesis and cell adhesion, among other biological roles. The human version of FEEL2 has a canonical amino acid length of 2551 residues and a protein mass of 277 kilodaltons. It is reported to be localized in the cell membrane and cytoplasm of cells.
