Biolegend, 398407, FITC anti-human CD32B/C Antibody, 25tests

CD32B (FCGR2B) and CD32C (FCGR2C) are 40 kDa, type I transmembrane proteins that are members of the Ig superfamily of low-affinity immunoglobulin gamma Fc receptors. CD32B has a cytoplasmic tail that contains an immunoreceptor tyrosine-based inhibition motif (ITIM), while CD32C contains an immunoreceptor tyrosine-based activation motif (ITAM). CD32B and CD32C are low affinity receptor for monomeric IgG but also bind IgG complexes. CD32B and CD32C are expressed on B cells, subsets of monocytes,macrophages and granulocytes, platelets, mast cells, and is a negative regulator of cell activation, proliferation, endocytosis, phagocytosis, and degranulation.

Verified Reactivity: Human
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: Extracellular domain of human CD32B
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)
Preparation: The antibody was purified by affinity chromatography and conjugated with FITC under optimal conditions.
Concentration: Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application: FC - Quality tested
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 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
Excitation Laser: Blue Laser (488 nm)
Application Notes: As the extracellular region of CD32B and CD32C are identical, this Ab recognizes both isoforms. Does not crossreact with CD32A.
