This affinity antibody is directed against Human TGFbeta1 protein. Cross-reactivity is expected with TGFbeta1 from non-mammalian sources as only a single amino acid residue change is found within the immunogen sequence from many other organisms.
交叉反应 (详细)
Species reactivity (expected):A BLAST analysis was used to suggest reactivity with this protein from most mammalian sources based on 100 % homology for the immunogen sequence. Species reactivity (tested):Human.

TGF-beta-1 is a multifunctional cytokine that belongs to a superfamily of structurally related regulatory proteins, including three mammalian TGFbeta isoforms (TGF-beta-1, -beta-2, and -beta-3), activin/inhibins and bone morphogenetic proteins. The most abundant isoform, TGF-beta-1, is a 25 kDa homodimer composed of two 12.5 kDa subunits joined by disulfide bonds. TGF-beta-1 is a highly conserved molecule, the amino acid sequence between human and mouse differs by only one residue. Although originally defined by its ability to cause anchorage independent cell growth and changes in cell morphology of rat fibroblasts, subsequent research has revealed that TGF-beta is actually a major growth inhibitor for most cell types. It is produced by a wide variety of cell and tissue types during all stages of cell differentiation. TGF-beta-1 sources include platelets, bone and soft tissues, such as placenta and kidneys.Synonyms: TGF-beta-1, TGFB, Transforming growth factor beta-1
