Specifications Source Mouse CD4/LEU3 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Lys27-Thr394.[Accession | NP_038516.1] Molecular Weight The protein has a predicted MW of 42.4 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on SDS- PAGE result. Endotoxin 95% as determined by SDS- PAGE and 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 conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Note 1.Please operate with lab coats and disposable gloves,for your safety. 2.This product is for research use only.
