Background: TGF-beta 1

TGF- beta 1 (transforming growth factor beta 1) is one of three closely related mammalian members of the large TGF-beta superfamily that share a characteristic cystine knot structure (1 - 7). TGF-beta 1, -2 and -3 are highly pleiotropic cytokines that are proposed to act as cellular switches that regulate processes such as immune function, proliferation and epithelial-mesenchymal transition (1 - 4). Each TGF-beta isoform has some non-redundant functions; for TGF-beta 1, mice with targeted deletion show defects in hematopoiesis and endothelial differentiation, and die of overwhelming inflammation (2). Human TGF-beta 1 cDNA encodes a 390 amino acid (aa) precursor that contains a 29 aa signal peptide and a 361 aa proprotein (8). A furin-like convertase processes the proprotein to generate an N-terminal 249 aa latency-associated peptide (LAP) and a C-terminal 112 aa mature TGF- beta 1 (8, 9). Disulfide-linked homodimers of LAP and TGF-beta 1 remain non-covalently associated after secretion, forming the small latent TGF-beta 1 complex (8 - 10). Covalent linkage of LAP to one of three latent TGF-beta binding proteins (LTBPs) creates a large latent complex that may interact with the extracellular matrix (9, 10). TGF-beta is activated from latency by pathways that include actions of the protease plasmin, matrix metalloproteases, thrombospondin 1 and a subset of integrins (10). Mature human TGF-beta 1 shares 100% aa identity with pig, dog and cow TGF-beta 1, and 99% aa identity with mouse, rat and horse TGF-beta 1. It demonstrates cross-species activity (1). TGF-beta 1 signaling begins with high-affinity binding to a type II ser/thr kinase receptor termed TGF-beta RII. This receptor then phosphorylates and activates a second ser/thr kinase receptor, TGF-beta RI (also called activin receptor-like kinase (ALK) -5), or alternatively, ALK‑1. This complex phosphorylates and activates Smad proteins that regulate transcription (3, 11, 12). Contributions of the accessory receptors betaglycan (also known as TGF-beta RIII) and endoglin, or use of Smad-independent signaling pathways, allow for disparate actions observed in response to TGF-beta in different contexts (11).

Application: competition ELISA Sample Tested: Recombinant protein Species: Mouse

I coated my plate with 50ng/well of recombinant mouse TGF beta 1 protein (cat# 7666-MB) overnight. I washed and blocked with reagent diluent 2 DY995 for 2hr, washed and added another company's TGFb1 antibody at different concentrations 0.2-100ug/mL in reagent diluent 2 and incubated 1hr. I did not wash my wells but add the two antibodies MAB240-biotinylated it in-house and BAF at a final concentration of 2ug/mL and incubated 1hr diluted in reagent diluent 2. I washed and added streptavidin-HRP DY998 (1:200) and incubated 30 mins, washed and developed with the substrate pack DY999. I found MAB240 competed for binding to the mouse TGF beta 1 protein when the competitor's antibody was present but the chicken polyclonal was not inhibited.
