 Product Gene Name   

CD152 protein

[Similar Products]
 Research Use Only    For Research Use Only. Not for use in diagnostic procedures.
Table BarTOPTable Bar
 Host    BHK cells
 Species Reactivity    Human, Primate, Mouse, Pig, Cow, Cat
Section Bar
 Form/Format    50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 5% Glycerol, 0.2% BSA.
 Concentration    0.25 mg/ml (lot specific)
Section Bar
 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).
Section Bar
 Preparation and Storage    Store at 2 - 5 degree C. Freeze/Thawing is not recommended.
Product should retain activity for at least 12 months after shipping date when stored as recommended.
 Other Notes    Small volumes of CD152 protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Related Product Information for CD152 protein

   Information: Immune response mediated by T cells can be characterized to functionally proceed as follows: antigen recognition by the T cell receptor, activation through costimulation, effector activities to eliminate antigen and finally down regulation. Human CD152 is a cell surface glycoprotein expressed at low levels on activated T cells. CD152 is a high affinity receptor for the costimulatory molecules CD80 (B7-1) and CD86 (B7-2) and appears to function as a negative regulator of T cell activation. Therefore, CD152 may be an important player in down regulating T cell mediated immune responses. The CD152 Ig fusion protein has biological activity and binds with high affinity to human or mouse CD80 (B7-1) and CD86 (B7-2). CD152 Ig will block the binding of anti-CD80 (B7-1) and anti-CD86 (B7-2) monoclonal antibodies.
 Applications Tested/Suitable for CD152 protein
