FC - Quality tested

Application Notes:

Additional reported applications for the relevant formats include: Western Blotting1 and immunohistochemical staining of frozen tissue sections3.

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 ≤0.125 µg per million cells in 100 µl volume.  It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 mouse splenocytes were stained

C57BL/6 mouse splenocytes were stained with CD19 Brilliant Violet 421™ and PIR-A/B (clone 6C1) PE (top) or rat IgG1, κ PE isotype control (bottom).


Paired-immunoglobulin-like receptor (PIR) is a type I transmembrane protein, containing six Ig-like domains. Two isoforms (PIR-A and PIR-B) have been reported for this molecule. PIR-A/B is expressed on B cells, mast cells, macrophages, granulocytes, eosinophils, and dendritic cells. PIR-A requires association with FcRγc for its cell surface expression and to act as an activating receptor. The ligand for PIR-A is MHC class I. PIR-B is an inhibitory receptor with 3 ITIM motifs on its cytoplasmic tail; when phosphorylated, they recruit the tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2. MHC class I, Nogo, MAG, and OMgp are the ligands for PIR-B.
