Figure 3.

Changes in Ag-specific titers as a function of purification methods. Various Ig preparations from (A) rabbit sera or (B) human serum or plasma were tested for changes in the MSP-1p42 specific titer (i.e., OD = 1 at 405 nm). Data shown are the geometric mean and 95% confidence interval of three independent experiments for each purification method. Asterisks indicate statistically significant differences (p < 0.05).
