Sino Biological CD4 Recombinant Human Protein, His Tag
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
Manufacturer: Invitrogen 10400H08H5
DescriptionCluster of Differentiation 4 (CD4), recombinant human protein is supplied as a lyophilized powder. 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.
- Activity: 1. Measured by its ability to bind to 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 (2.5µg/mL and 100µL/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 0.2mg/mL or lower; aliquot and use as soon as possible
