| Description : |
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 (TGFb1, TGFb2 and TGFb3) signal through the same receptor and stimulate similar biological responses. They are involved in physiological pr centigradeesses as embryogenesis, tissue remodelling and wound healing. |
| Form : |
Lyophilized from a concentrated (1mg/ml) solution containing 50mM Tris-HCl pH-7.4. |
| Bio-activity : |
The biological activity of TGFB2 is measured in culture by its ability to inhibit the mink lung epithelial (Mv1Lu) cells proliferation. ED50< 40ng/ml,="" corresponding="" to="" a="" specific="" activity="" of="" 25,000=""> |
| Molecular Mass : |
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. |
| Purity : |
Greater than 97.0% as determined by SDS-PAGE. |

| Usage : |
FOR RESEARCH USE ONLY |
| Quality Control Test : |
Lyophilized TGFB2 although stable at room temperature for 3 weeks, should be stored desiccated below -18 centigrade. Upon reconstitution TGFB2 Human should be stored at 4 centigrade between 2-7 days and for future use below -18 centigrade. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
| Reconstitution : |
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. |
| Warning : |
Avoid repeated freeze-thaw cycles. |
