TW7-16B4_APC_1_062911
CD3+CD28+IL-2-stimulated C57BL/6 mouse splenocytes (48 hours) were surface stained with CD4 FITC and LAP (clone TW7-16B4) APC (top) or mouse IgG1, κ APC isotype control (bottom), then intracellularly stained with FOXP3 PE. Data shown was generated by gating on CD4+ lymphocyte population.

Description

Transforming growth factor beta (TGF-β) is a cytokine that has critical functions in the immune response by regulating Treg and Th17 cells. TGF-β is first synthesized as pro-TGF-β and then it is cleaved by furin proprotein convertase in the Golgi apparatus to produce the dimeric propeptides called latency-associate peptide (LAP) that non-covalently associates with the dimeric mature TGF-β to prevent its activity. This complex can further associate with latent-TGF-β-binding protein (LTBP) to produce a large latent form for deposition onto the extracellular matrix. The latent-TGF-β can be expressed on the membrane of activated Treg cells, immature dendritic cells, megakaryocytes, and platelets.

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 ≤0.5 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
