Dissociation Constant (Kd) Calculator
Calculate Kd from equilibrium concentrations, Ka, kinetic rates, or thermodynamic data
Calculation Method
Dissociation Constant (Kd)
1111.111 mM
1.1111e+0 M
Ka
9.000e-1 M^-1
Delta G
0.26 kJ/mol
Calculation
Kd = [R][L]/[RL] = (5 x 10)/45
Kd Interpretation
- Kd = concentration at 50% saturation
- Lower Kd = tighter binding
- Kd = [R][L]/[RL] at equilibrium
