Target: MS4A4A (Membrane-Spanning 4-Domains, Subfamily A, Member 4 (MS4A4A))

Antibody Type: Recombinant Antibody

Reactivity: Human

Host: Rabbit

Clonality: Chimeric

Conjugate: This MS4A4A antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunoprecipitation (IP)

Clone: 5C12

Product Details anti-MS4A4A Antibody

Purpose: Anti-MS4A4A [5C12], Rabbit IgG, lambda

Specificity: This antibody is specific for human extracellular MS4A4A. 5C12 mAb only partially cross-blocked either 4H2 (Ab01373) and 3F2 (Ab01375) and therefore probably detects a unique or overlapping epitope (Sanyal et al., 2017, pmid: 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.

Characteristics:

Original Species of Ab: Mouse

Original Format of Ab: IgG1

Purification: Protein A affinity purified

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.

Isotype: IgG lambda

Application Details

Application Notes: 5C12 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 5C12 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).

Comment:

This chimeric rabbit antibody was made using the variable domain sequences of the original Mouse IgG1 format, for improved compatibility with existing reagents, assays and techniques.
