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. K D value. Molar concentration (sensitivity) 10 -4 to 10 -6. Micromolar (µM)
