For pulse activation experiments, the COS-1 cells were incubated with sCD4 (40 mg/ml, 0.8 mM) or 191 (360 mM) suspended in blocking buffer for three minutes, washed three times with blocking buffer and incubated for different time periods until the C34-Ig or 48d antibodies were added (at 40 mg/ml or 1 mg/ml, respectively, for 30 minutes). To study the tem
To current convention [46]). C34-Ig was produced and purified as previously described [47]. The CD4-Ig fusion protein consists of the first two N-terminal domains of the CD4 molecule and the Fc region of human IgG1.
