Description

CD256 (APRIL, TNFSF13, TALL2, TRDL1) a transmembranal protein of 26 kD, forms a homotrimeric molecule that is cleaved from the cell surface resulting in the soluble form of APRIL; it also forms heterotrimers with BLyS. Its receptor are TNFRSF13b/TACI and TNFRSF17/BCMA. Expressed by T cells, B cells, dendritic cells, monocytes, and macrophages, APRIL induces proliferation of T and B cells, promotes IgA class switching, downregulates T-cell dependent antibody responses, and regulates the growth of a variety of tumor cells.

Formulation

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 microg per million cells in 100 microL volume. It is recommended that the reagent be titrated for optimal performance for each application.
