Background
TGF-β3 can induce cell proliferation and angiogenesis, and can promote some immune events while inhibiting others (1-3). TGF-β3 is produced by chondrocytes, glial cells, astrocytes and some cancer cells (3,4). TGF-β3 binds to TβRII homodimer, which then complexes with TβRI homodimer (1,5). The oligomeric receptor complex phosphorylates subsets of SMAD proteins that then act to induce or suppress target genes (1,5). Based on knock-out studies in mice, TGF-β3 is critical for lung and palate development (6).

Endotoxin
Less than 0.01 ng endotoxin/1 μg hTGF-β3.
Purity
>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hTGF-β3. Less than 5% migrates as monomer hTGF-β3 under non-reduced (-) conditions. All lots are greater than 98% pure.
Source / Purification
Recombinant human TGF-β3 (hTGF-β3) Ala301-Ser412 (Accession #NP_003230) was expressed in human 293 cells at Cell Signaling Technology.
Bioactivity
The bioactivity of recombinant hTGF-β3 was determined by assessing inhibition of IL-4 induced HT-2 cell proliferation. The ED50 of each lot is between 0.02-0.1 ng/ml.
