"High affinity" refers to very strong binding (large negative ∆Go and a very small K d). The association or dissociation constant is often referred to as the "affinity” or “binding” constant.
Biotin and avidin bind with a dissociation constant of roughly 10 −15 M = 1 fM = 0.000001 nM. Ribonuclease inhibitor proteins may also bind to ribonuclease with a similar 10 −15 M affinity.
