Recombinant Human IL7R protein (Glu21-Gly236), His-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : C-His | Protein length : Glu21-Gly236 | Form : Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. | Bio-activity : Human IL-7 R alpha, His Tag captured on CM5 Chip via anti-his antibody can bind Human IL-7, No Tag with an affinity constant of 4.18 nM as determined in SPR assay (Biacore T200). | Molecular Mass : The protein has a predicted MW of 25.7 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis PAGE result. | Endotoxin : Less than 1EU per μg by the LAL method. | Purity : > 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC | Storage : -20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. | Reconstitution : Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
