WebIn many models, the instantaneous formation of the equilibrium is assumed. In general, the isotherm equation is expressed by the rate of change of the concentration of the adsorbed species over time. Langmuir Model . Historically, the Langmuir isotherm is the most extensively studied model. This model considers single-point binding only. WebThis equation describes a rectangular hyperbola or a binding isotherm. [L] is the concentration of free radioligand, the value plotted on the X axis. Bmax is the total number of receptors expressed in the same units as the Y values (i.e., cpm, sites/cell or fmol/mg protein) and Kd is the chisholm style guide
