Description
The TW4-9E7 monoclonal antibody specifically binds to Human Transforming Growth Factor beta-1 (TGF-β1). TGF-β1 is a potent multifunctional cytokine that positively or negatively regulates numerous processes including development, hematopoiesis, tissue remodeling, wound repair, innate and adaptive immunity as well as cancer and autoimmune diseases. TGF-β1 is formed by the enzymatic cleavage of the TGF-β1 propeptide that is encoded by the TGFB1 gene and comprised of the Latency Associated Peptide (LAP) and TGF-β1. Prior to secretion, the dimeric LAP-TGF-β1 propeptide is cleaved resulting in a biologically inactive form of dimeric TGF-β1 that is noncovalently associated with dimeric LAP (latent TGF-β1). This complex may be expressed on the surface of TGF-β1-producing cells or be further processed by proteolytic removal of LAP to release the biologically active mature form of the soluble TGF-β1 homodimer. Many different cell types synthesize TGF-β1 and express specific receptors for it. The TW4-9E7 antibody recognizes both the intracellular latent bound form of TGF-β1 along with the membrane bound form of TGF-β1.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 488 under optimum conditions, and unreacted Alexa Fluor® 488 was removed.
1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
