CD152 IgG2a Fc, Fusion Protein (CD152) Protein

For Research Use Only. Not for use in diagnostic procedures. Catalog #: MBS634987

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… More details

Product Overview

Online Datasheet in PDF
Product Name
CD152 IgG2a Fc, Fusion Protein
Full Product Name
CD152 IgG2a Fc, Fusion Protein (CTLA4, Cytolytic T-lymphocyte-associated Antigen 4) (FITC)
Host
BHK cells
Form/Format
50 mM Sodium Phosphate pH 7.5, 100 mM PotassiumChloride, 150mM NaCl, 5% Glycerol, 0.2% BSA, 0.04% NaN3 (as apreservative).
Preparation and Storage
May be stored at 4 degree C. For long-term storage, aliquot and store at 4 degree C. Do not freeze. Aliquots are stable for at least 6 months. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
Molecular Weight
40.1kD
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
Functional Application
CD152 Ig binds with high affinity to human or mouse CD80 (B7-1) and CD86 (B7-2)(4, 5). CD152 Ig blocks the binding of anti-CD80 (B7-1) and anti-CD86 (B7-2) mAbs.
Human CD152(CTLA-4) Ig/FITC Fusion Protein*(also binds to mouse CD80/CD86)
Transfectant Cell Line
BHK
Production
Human CD152 Ig fusion protein from tissue culturesupernatant of BHK transfectants was Protein A purified to >95% bySDS-PAGE (<1% bovine immunoglobulin), and reacted with FITC.Unconjugated FITC was removed from conjugate using a desalting column. The fusion protein/FITC conjugate is at 20 ug/ml with a Fluorescein/IgG molar ratio of 10.8.
Performance
Five x 105 cultured Raji human tumor cells were washed and incubated 45 minutes on ice with 80 ul of CD152 Ig/FITC at a 1:20 dilution factor (1 ug/ml). Cells were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 0.93 log10 fluorescent units when compared to a Mouse IgG2a/FITC negative control (MBS666101). Binding was blocked when cells were preincubated 10 minutes with 20 ul of 0.5 mg/ml unlabeled CD152-muIg(MBS666792).
Applications Tested/Suitable for CD152 IgG2a Fc, Fusion Protein protein
ELISA (EL/EIA), Flow Cytometry (FC/FACS)
Working Dilutions: 1:20 (or use 4ul of concentrated stock per 5 x 105-cell test)

Other Notes

Small volumes of CD152 IgG2a Fc, Fusion Protein 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.
