A soluble molecule consisting of the mature extracellular (213 aa) domain of human CD275 (GL50,ICOS L) fused to the murine IgG2a Fc (233 aa). (449 aa total). The molecule is dimeric with a predicted monomeric non glycosylated molecular weight of 50.3 kd. Five x 10^5 human HPB-MLT cells were washed and incubated 45 minutes on ice with 80 µl of CD275trn-muIg at 5 µg/ml. Cells were washed twice and incubated with secondary reagent Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 0.89 log10 fluorescent units when compared to a buffer controlat a similar concentration. Binding was blocked when reagent was pre incubated with a 5-fold excess of recombinant CD278(ICOS)-muIg.
