Figure 2. Binding of anti-CPSIII mAbs to intact GBS, neuraminidase-treated GBS, or purified CPSIII.
Elisa plates were coated with intact or neuraminidase treated GBS, or with purified capsular polysaccharide. Mabs were incubated in the wells at 3 μg/ml and detected with alkaline phosphatase-conjugated anti-mouse Ig. Data are the absorbance at 405nm, mean and SEM.
