Biotinylated Human IL-2R gamma/CD132 Protein, His-Avi Tag

Specifications Source Biotinylated Human IL-2 R gamma/CD132 Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Leu23-Asn254.[Accession | P31785-1] Molecular Weight The protein has a predicted MW of 39.9 kDa. Due to glycosylation, the protein migrates to 58-70 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 Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.   Storage The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~8 °C under sterile conditions after reconstitution. 3 months, -25~-15℃ under sterile cond
