Our knowledge of the role of proteins in cellular processes is continually evolving. Most proteins, including CD152 are typically involved in one or more signaling pathways or biological processes. Professionally manufactured recombinant proteins are increasingly becoming essential and commonplace tools for elucidating new knowledge about the role of proteins in both health and disease.
Molecular Structure: A soluble 110 kd dimeric fusion protein consisting of the extracellular (125aa) domain of human CD152 (CTLA-4) fused to murine IgG2a Fc
Transfectant Cell Line: BHK
Performance: Five x 105 cultured Raji human tumor cells were washed and incubated 45 minutes on ice with 80 ul of CD152-muIg/Biotin at a concentration of 0.5 ug/ml. Cells were washed twice and incubated with 2 degree reagent Streptavidin/R-Phycoerythrin, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 1.81 log10 fluorescent units when compared to Recombinant muIg/Biotin negative control at a similar concentration. Binding was blocked when cells were pre blocked with 20 ul of 0.5 mg/ml unlabeled CD152-muIg. Conjugation: Biotin
Production: Human CD152 Ig fusion protein from tissue culture supernatant of BHK transfectants was Protein A purified to >95% by SDS-PAGE (<1% bovine immunoglobulin), and reacted with NHS-Biotin. Unconjugated Biotin was removed from conjugate using a desalting column.
Buffer: 50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 5% Glycerol, 0.2% BSA, 0.04% NaN3 (as a preservative).
