TGFB2 is a 27.08 kDa protein having two identical 118 amino acid peptide chains linked by a single disulfide bond. TGFB2 is part of a family of five related cytokines that have an extensive variation of normal and neoplastic cells, indicating the importance of these homo-dimmer proteins as multi-functional regulators of cellular activity. The three mammalian isoforms of TGF-β signal through the same receptor and stimulate similar biological responses. They are involved in physiological processes as embryogenesis, tissue remodelling and wound healing.

TGFB2 Human Recombinant produced in plants is a homodimeric polypeptide chain containing 2 x 118 amino acids and having a total molecular mass of 27.08kDa. The TGFB2 is fused to 6xHis Tag at N-terminus and purified by proprietary chromatographic techniques.

Nicotiana benthamiana.

Sterile Filtered White lyophilized powder.

Lyophilized from a concentrated solution containing 50mM Tris-HCl pH-7.4.

It is recommended to reconstitute the lyophilized TGFB2 in sterile 18M-cm H₂O not less than 1µg/40µl, which can then be further diluted to other aqueous solutions.

Lyophilized TGFB2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TGFB2 Human should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein . Please prevent freeze-thaw cycles.

Greater than 97.0% as determined by -PAGE.
