Hill Equation Calculator

Calculate fractional occupancy and response using the Hill equation for cooperative ligand binding

Input Parameters

Ligand Concentration [L] (nM)

Dissociation Constant Kd (nM)

Hill Coefficient (n)

Maximum Response Vmax

Fractional Occupancy

80.00%

Response

80.00

EC50

5.0000 nM

Cooperativity Type

Positive

Hill Equation Formula

Y = (Vmax * [L]^n) / (Kd^n + [L]^n)

Where n > 1 indicates positive cooperativity, n < 1 indicates negative cooperativity
