Anti-MS4A4A [5C12] Antibody

This mouse IgG1 monoclonal antibody [5C12] was generated against mouse cell line 300-19 expressing transfected human membrane-spanning 4-domains subfamily A member 4 (MS4A4A)-GFP and is specific for human extracellular A MS4A4A.


  • Reacts with human MS4A4A
  • Suitable for FACS and Immunoprecipitation applications

MS4A (membrane-spanning 4-domain family, subfamily A) is a large family of proteins that includes at least 26 members in mouse and humans. Flanked by amino- and carboxyl- cytoplasmic regions, MS4A family members contain four highly conserved transmembrane domains connected by short extracellular and cytoplasmic loops. CD20, the most well-known MS4A family member, is a B-cell-specific molecule associated with the B cell antigen receptor and functions in receptor-activated calcium influx. Several other MS4A family members are likely to be components of oligomeric cell surface complexes involved in signal transduction in diverse cell lineages.
