Description

TGF-β1 is a multifunctional cytokine that plays pivotal roles in diverse biological processes. TGF-β1 is synthesized as a 390 amino acid precursor that is cleaved by furin, localized in the trans-Golgi network, in residue 278.  Furin processes the TGF-β1 precursor at the carboxyl side of the consensus sequence RHRR which precedes the NH2-terminal Ala 279 residue of the mature TGF-β1. The TGF-β1 precursor includes the latency-associated peptide (LAP dimer) in the N-terminal portion and the 25 kD portion that constitutes the mature TGF-β1 in the C-terminal. LAP dimer and the TGF-β1 mature protein remain non-covalently associated after furin cleavage and this complex does not bind to the TFG-β1 receptor. In addition, the TGF-β1 latent complex is joined covalently through LAP to LTBP. The TGF-β1 active form requires dissociation from LAP. Some activators can release TGF-β1 from LAP such as thrombospondin-1, reactive oxygen species, and the integrins avb6 and avb8.

Mouse TGF-β1 converts naïve T cells into regulatory T (Treg) cells that prevent autoimmunity. Although human TGF-β1 is widely used for inducing FOXP3+ in vitro, it might not be an essential factor for human Treg differentiation. Th17 murine can be induced from naïve CD4+ T cells by the combination of TGF-β1 and IL-6 or IL-21. Nevertheless, the regulation of human Th17 differentiation is distinct. TGF-β1 seems to have dual effects on human Th17 differentiation in a dose-dependent manner. While TGF-β1 is required for the expression of RORgt, in human naïve CD4+ T cells from cord blood, TGF-β1 can inhibit the function of RORgt at high doses. By using serum-free medium, it has been clarified that the optimum conditions for human Th17 differentiation are TGF-β1, IL-1b, and IL-2 in combination with IL-6, IL-21, or IL-23.

Application

ELISA Detection - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by ELISA assay. A concentration of 0.0625 µg/ml of the detection antibody was utilized to generate the example standard curve. It is recommended that the end-user titrate each lot of reagents for optimal performance.

Application Notes

ELISA Detection: To measure TGF-β1, this antibody can be used as a detection antibody in sandwich ELISA format, and paired with the purified 21C11 antibody (Cat. No. 525301) as the capture antibody. Recombinant Human TGF-β1 (ELISA Std.) (Cat. No. 580709) can be used as the protein standard.

Blocking: Clone 19D8 LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is useful for in vitro blocking of human and mouse TGF-β1 bioactivity. The 19D8 clone does not inhibit the bioactivity of human TGF-β2 or TGF-β3 in the Mv1Lu-(caga)12-Luc reporter cell assay.

Note: For testing TGF-β1 in serum, plasma or supernatant, BioLegend's ELISA LEGEND MAX™ Kits (Cat. No. 436708 & 437708) are specially developed and recommended.

Antigen Details

Structure
Homodimer
Distribution

TGF-β1 is secreted by numerous cells.

Function
TGF-β1 influences the fate of T cells into different subpopulations depending on the occurrence of other cytokines. TGF-β1 induces cell growth and survival, cell and tissue differentiation, development, inflammation, immunity, hematopoiesis, tissue remodeling, wound healing, and stimulates ECM deposition and angiogenesis. It is an essential mediator of pathologic scarring in fibrotic disorders.
Interaction
Multiple cells express the TGF-β1 receptors.
Ligand/Receptor
Heterodimeric receptor consisting of type I (TbRI) and type II (TbRII).
