The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. Test size products are transitioning from 20 µl to 5 µl per test. Please check your vial or your CoA to find the suggested use of this reagent per million cells in 100 µl staining volume or per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application. Read more at www.biolegend.com/testsize regarding the test size change.

Description
FcRL4 (Fc receptor-like 4) is a 57 kD single pass type I transmembrane protein that exhibits 4 Ig like C2 domains. Also known as ITRA1, IGFP2, and FcRH4, FcRL4 is predominately found on a subset of memory B cells. Activation of FcRL4 contributes to B cell receptor inhibition through activation of the tyrosine kinases SHP-1 and 2. FcRL4's nascent loci is 1q23.1; however, breakpoint mutations are associated with multiple myeloma and non-Hodgkins lymphoma. Increased FcRL4 expression on memory B cells has also been observed in HIV viremic patients. FcRL4 predominately binds aggregated IgA, binds weakly with IgG3 and IgG4, and does not bind IgG1 and IgG2.
Storage
The antibody solution should be stored undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
