Figure 2

Representative chromatogram during removal of highly abundant serum proteins by an immunoaffinity column. 100 μL of serum (diluted fivefold) was injected on the immunoaffinity column and was eluted (0.5 mL/min) as described in the experimental procedures. Flow-through fractions (12.1–20.0 min) were collected, and then a total of 4.0 mL fractions were concentrated to a volume of 80 μL using Vivaspin 2 for reversed-phase HPLC fractionation.
