Anti-CD99 molecule-like 2 antibodies enable researchers to detect and measure the CD99 molecule-like 2 antigen in biological samples. This target is a reported synonym of the CD99L2 gene, which encodes CD99 molecule like 2. This protein is known to function in cell adhesion, among other biological roles. The human version of CD99 molecule-like 2 has a canonical amino acid length of 262 residues and a protein mass of 28 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the cell membrane and is secreted of cells and widely expressed in many tissue types. CD99 molecule-like 2 is a member of the CD99 protein family.
