extension to nlme self start SSmicmen?
Dear list, Has anyone created a version of SSmicmen that allows testing for group differences? The basic Michaelis-Menten equation is: (Bmax * X) / (Kd + X). The nlme package allows modeling of random effects for Bmax and Kd as needed, but I curious how I can build in group differences? I have receptor binding data for strains of mice, and following Pinheiro and Bates' lead in their book, a random effort for animal difference...

Complicated nls formula giving singular gradient message
...Prism for, because the formula isn't pretty by any means. Prism presents the formula (which is in the Prism equation library as Heterologous competition with depletion, if anyone is curious) in these segments: KdCPM = KdnM*SpAct*Vol*1000 R=NS+1 S=(1+10^(X-LogKi))*KdCPM+Hot a=-1*R b=R*S+NS*Hot+BMax c = -1*Hot*(S*MS+BMax) Y = (-1*b+sqrt(b*b-4*a*c))/(2*a) I'm only trying to solve for NS, LogKi, and BMax. I have everything else (KdnM, SpAct, Vol, Hot). I would use the simple formula at the bottom and then backsolve for the terms I'm looking for, but the simple formula at the bottom tak...

saturation binding in nlme
To estimate saturation binding parameters Bmax and Kd in a receptor saturation binding experiment, I use the following nonlinear equation and the nls() function: bmax*X*dummy ------------ + ns*X + background = total binding kd+X where X is concentration, and dummy is an indicator to allow shared estimation of the nonspecific binding pa...

one-site competition data // curve fitting
Hello everyone, I have biological data from a competition experiment where a free ligand is titrated against the binding of a protein. Now, I would like to fit a standard on-site binding curve to this data in order to obtain the IC50 and Kd values. Unfortunately I have not been able to find a package/function which allows such a fitting and calculates the results. Does anyone know if there is
