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.

-
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 -
