Testing Data
other info1 :
Molecular Structure: A soluble molecule consisting of the extracellular domain (132 aa) of human CD252 fused to the extracellular domain (167aa) of murine CD8 alpha. Transfectant Cell Line: CHO. Performance: Five x 10 5 cultured human HPB-MLT cells per tube were washed and incubated 45 minutes on ice with 80 ul of CD252-muCD8/Biotin at a concentration of 10 ug/ml. Cells were washed twice and incubated with 2 degree reagent Streptavidin/R-PE, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 0.9 log 10 fluorescent units when compared to a buffer control. Binding was blocked when reagent was pre incubated with anti-CD252 antibody at a concentration of 100 ug/ml.
other info2 :
Conjugation: Biotin. Production: Fusion protein from (low FBS containing) tissue culture supernatant of transfectants was purified using affinity and size exclusion chromatography), 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).
products description :
Information: Human CD252 (CD134L, OX-40 Ligand) is a type II membrane protein with homology to TNF which is expressed on activated B cells and activated endothelial cells. CD252 is involved with costimulatory activity between B cells and T cells (1). CD252-muCD8 fusion protein binds to CD134 positive cells in Flow cytometry.
