FC - Quality tested

Application Notes:

Additional reported (for relevant formats) application include: blocking binding of both IgM and IgA to the mFcα/µ receptor2.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤2.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Con-A stimulated C57BL/6 splenocytes (3

Con-A stimulated C57BL/6 splenocytes (3 days) were stained with CD3 APC and CD351 (clone TX-61) PE (top) or mouse IgG1, κ (bottom).


Fcα/µ receptor (Fcα/µR), CD351, is a type I transmembrane protein with an Ig-like domain in extracellular portion.  It is a novel Fc receptor for IgM and IgA.  Fcα/µ receptor mRNA has been found in thymus, spleen, liver, kidney, intestines, testes, placenta, and T cell leukemia cell lines.  Fcα/µ receptor protein expression is detected on B cells, macrophages, and activated T cells.  Fcα/µ receptor mediates primary B lymphocyte endocytosis of IgM-coated Staphylococcus aureus.   It is involved in the primary stages of the immune response to microbes.

Other Names: Fcα/μ receptor, Fcα/μR
Structure: About 70 kD transmembrane glycoprotein with an Ig-like domain in extracellular portion.
Distribution: B cells, macrophages, and activated T cells.
Function: Mediate primary B lymphocyte endocytosis and involve in the primary stages of the immune response to microbes.
Ligand Receptor: IgA and IgM
