Latent transforming growth factor beta-3 (TGF-beta-3) preprotein serves as a precursor to latency-associated peptide (LAP) and active TGF-beta-3 chains, which serve as regulatory and functional subunits. It plays a crucial role in maintaining the latent state of TGF-β-3 within the extracellular matrix. Animal-Free TGF beta 3/TGFB3 Protein, Human (His) is the recombinant human-derived animal-FreeTGF beta 3/TGFB3 protein, expressed by E. coli , with C-His labeled tag. This product is for cell culture use only.
