It is suitable for use in analysis of protein structure, studying protein-protein interactions, and cell biology research applications. It can also be used as an immunogen, or as a protein standard. This recombinant protein was expressed from a DNA sequence encoding the extracellular domain (Met 1-Trp 390) of human CD4 (NP_000607.1) fused to a polyhistidine tag at the C-terminus.Activity: 1. Measured by its ability to bind towith HIV-1 gp120 in a functional ELISA. 2. Measured by the ability of the immobilized protein to support the adhesion of HeLa human cervical epithelial carcinoma cells . When 5 x 10⁴ cells/well are added to CD4 coated plates (2.5 µg/mland 100 µl/well), approximately 60-80% will adhere specifically after 60 minutes at 37°C.Formulation: Lyophilized in PBS, pH 7.4, 5% Mannitol, 5% Trehalose, and 0.02% Tween 80.Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles. Expiration Date: Expires one year from date of receipt when stored as instructed.This protein is manufactured by Sino Biological Inc. 规格
