Basic Information | |
Specificity | This antibody is specific for human extracellular MS4A4A. The 4H2 and 3F2 (Ab01375) mAb clones completely cross-block one another indicating that they might bind to the same epitope or proximal epitopes (Sanyal et al., 2017; pmid:P 28303902). 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. MS4A4A is likely to be a component of oligomeric cell surface complexes involved in signal transduction in diverse cell lineages. |
Alternative Name | Four-span transmembrane protein 1; human membrane-spanning 4- domains subfamily A member 4A; CD20 antigen-like 1; (MS4A4A)-GFP; MS4A4; 4SPAN1; MS4A |
UniProt | Q96JQ5 |
Immunogen | This antibody was generated by immunizing C57BL/6 mice against mouse cell line 300-19 expressing transfected human membrane-spanning 4-domains subfamily A member 4A (MS4A4A)-GFP. |
Application Notes | 4H2 is recommended for the detection and analysis of expression of MS4A4A. Importantly, MS4A4A has been shown to be a marker for M2 macrophages and plasma cells and to be overexpressed in multiple myelomas, suggesting a potential role in targeting alternatively activated macrophages such as tumor-associated macrophages, and in the treatment of multiple myeloma and mantle cell lymphoma (Sanyal et al., 2017; pmid: 28303902). The antibody 4H2 can be successfully used for the detection of MS4A4A-expressing cells via flow cytometry (Sanyal et al., 2017; pmid: 28303902). Finally, specificity of this antibody was additionally confirmed via immunoprecipitation of lysates of BJAB MS4A4A- HA cells (Sanyal et al., 2017; pmid: 28303902). |
