Meaning of observed affinity (K App ), (fractional) response, and EC50 in the quaternary complex model under different limiting conditions

[B] = 0[G] = 05-a
KApp Formula Formula
Response Formula Formula
EC50 Formula Formula
  • 5-a  In the absence of [G], the expression for response is more accurately defined as the stimulus and is equal to ([R*] + [AR*] + [BR*] + [AR*B])/[R]T.
