Recombinant Mouse IL-7 Rα

CD127 (IL7R-α) is a 60-90 kD type I cytokine receptor involved in the regulation of lymphopoiesis. The active receptor is an α/γ chain heterodimer. The common γ chain, which also associates with the IL-2 receptor, serves mainly to activate signal transduction via the IL7R complex. CD127 also interacts with the Thymic Stromal Lymphopoietin Receptor (TSLPR). CD127 determines signaling events via its association with cytoplasmic signaling molecules and has been reported to be a useful marker for identifying memory and effector T cells.

Lyophilized

The predicted molecular weight of Recombinant Mouse IL-7 Rα is Mr 51.6 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 55-60 kDa.

51.6

This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
