An alternative approach that is closer to absolute quantitation of binding sites for individual mAbs is use of the so-called "antigen-binding capacity" (or ABC) beads. While the Mean might be most useful when used to describe normal distributions and not bi-modal or multi-modal data, the Median is a non-parametric statistic in that it is a better indicator of the central tendency of your data, regardless of the underlying data distribution.
