| Cat. No. : |
IL7R-129H |
| Description : |
Interleukin 7 (IL-7) is a cytokine that is essential for lymphopoiesis as well as T cell homeostasis and the maintenance of T cell diversity. Additionally, IL-7 promotes T cell cytolytic responses, and acts as co-stimulator for the activation of mature B cells. |

| Molecular Mass : |
IL-7R alpha-Fc Chimera migrates as a broad band between 75 and 90 kDa in SDS-PAGE due to post-translation modifications, in particular glycosylation. This compares with the unmodified IL-7 R alpha-Fc Chimera that has a predicted molecular mass of 50.0kDa. |
| PI : |
IL-7 R alpha-Fc Chimera separates into a number of isoforms with a pI between 5.9 and 7.4 in 2D PAGE due to post-translational modifications, in particular glycosylation. This compares with the unmodified IL-7R alpha-Fc Chimera that has a predicted pI of 6.34. |
| % Carbohydrate : |
Purified IL-7R alpha-Fc Chimeraconsists of 30-45% carbohydrate by weight. |
| Glycosylation : |
IL-7R alpha-Fc Chimera is N-glycosylated and may be O-glycosylated. |
| 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. Repeated freeze thawing is not recommended. |
