| Description : |
Transforming growth factor-beta (TGF-beta; TGF-b) is a pleiotropic cytokine that controls the growth, survival, motility and differentiation of cells. It is involved in the degradation and remodelling of the extracellular matrix (ECM), and has an important role in development during embryogenesis. The biological effects of TGF-beta are mediated by binding to TGF-beta receptors; TGF-beta RI, TGF-beta RII (TGF-beta R2 ) , and TGF-beta RIII ( TGF-beta R3 ). TGF-beta RII is synthesized as a 567 amino acid protein including a 22 amino acid signal sequence, a 144 amino acid extracellular domain, a 21 amino acid transmembrane domain and a 380 amino acid cytoplasmic domain containing a Ser/Thr protein kinase. TGF-beta RII contains 3 N-linked glycosylation sites. |

| Molecular Mass : |
TGF-beta RII-Fc Chimera migrates as a broad band between 45 and 70 kDa in SDS-PAGE due to post-translation modifications, in particular glycosylation. This compares with the unmodified TGF-beta RII-Fc Chimera that has a predicted molecular mass of 42.7kDa. |
| PI : |
TGF-beta RII-Fc Chimera separates into a number of isoforms with a pI between 4.7 and 7.2 in 2D PAGE due to post-translational modifications, in particular glycosylation, the. This compares with the unmodified TGF-beta RII-Fc Chimera that has a predicted pI of 6.22. |
| % Carbohydrate : |
TGF-beta RII-Fc Chimera consists of 5-40% carbohydrate by weight. |
| Purity : |
>95%, as determined by SDS-PAGE and visualized by silver stain. |
| Formulation : |
When reconstituted in 0.5 ml sterile phosphate-buffered saline, the solution will contain 1% human serum albumin (HSA) and 10% trehalose. |
| Reconstitution : |
It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. |
| Storage : |
Lyophilized products should be stored at 2 to 8°C. Following reconstitution short-term storage at 4°C is recommended, and longer-term storage of aliquots at -18 to -20°C. |
