TW7-20B9_PE_1_031711
C57BL/6 mouse splenocytes were stimulated with anti-mouse CD3, CD28, and recombinant mouse IL-2 for 48-hours, then surface stained with CD4 FITC and LAP (TGF-β1) (clone TW7-20B9) PE (top) or mouse IgG1, κ PE isotype control (bottom). This was followed by intracellular staining with FOXP3 Alexa Fluor® 647. 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 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-associated 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.

Application

FC - Quality tested
IP, WB, Neut - Reported in the literature, not verified in house
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 ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Clone TW7-20B9 has been reported to not cross-react with human LAP.2 Several anti-LAP antibody clones have been compared and characterized for their LAP reactivity.2 This antibody recognizes recombinant LAP, latent TGF-ß, and pro-TGF-ß.

Additional reported applications (for relevant formats) include: Western blotting1, immunoprecipitation1, and neutralization2. TW7-20B9 is able to neutralize certain unconventional T cell-derived forms of TGF-ß activity, but not the distinct 25 kDa free form of TGF-ß.2
