Table 1.
mAb | Displacement, % |
---|---|
sCD4D1D2 | 53 |
MIP-1α | 100 |
CG7 + sCD4D1D2 | 2.5 |
CG10 + sCD4D1D2 | 56 |
CG1 + sCD4D1D2 | 47 |
The anti-CD4 mAb CG7 inhibits the displacement of CCR5-bound MIP-1α by a soluble CD4 fragment containing its first two domains (sCD4D1D2). The antibodies were used at a concentration of 60 nM; the signal-to-noise ratio was greater than 10.
