Citation 27 A phage display-derived anti-nerve growth factor antibody was successfully affinity optimized to 69 pM K D , but with this came a concomitant increase in viscosity and aggregation, with significantly increased retention on an SEC column that resulted from ... WebK D and affinity are inversely related. The K D value relates to the concentration of antibody (the amount of antibody needed for a particular experiment) and so the lower the K D value (lower concentration) and thus the higher the affinity of the antibody.
