Shipping: Gel pack

Background Information: Transforming growth factor betas （TGFβ） mediate many cell-cell interactions that occur during embryonic development. Three TGFβs have been identified in mammals. TGF Beta 1, TGF Beta 2 ａnd TGF Beta 3 are each synthesized as precursor proteins that are very similar in that each is cleaved to yield a 112 amino acid polypeptide that remains associated with the latent portion of the molecule. TGF-beta 1 is involved in hematopoiesis ａnd endothelial differentiation.

Amino Acid Sequence: N/A
