Monoclonal antibody 90.12 recognizes a molecule expressed on the surface of a subset of B lymphocytes and on all types of blood cells. This antigen is increased upon stimulation of B and T lymphocytes as well as on cells undergoing programmed cell death. Amino acid sequencing of the beginning of the protein suggests that it is a member of the S100 family of calcium binding proteins.
