In its proprotein form, the TGF beta-1/TGFB1 protein serves as a precursor to latency-associated peptide (LAP) and active transforming growth factor beta-1 (TGF-beta-1) chains.Critical to maintaining the latent state of TGF-β-1 within the extracellular matrix, preprotein interacts with “environmental molecules” such as LTBP1, LRRC32/GARP, and LRRC33/NRROS to regulate TGF-β-1 activation.Animal-Free TGF beta 1/TGFB1 Protein, Mouse/Rat (His) is the recombinant mouse-derived animal-FreeTGF beta 1/TGFB1 protein, expressed by E.coli , with C-His labeled tag.This product is for cell culture use only.
