Example files. Five MATLAB scripts, each of which plots ligand-receptor complex as a function of ligand concentration for different values of the dissociation constant KD. The scripts are numbered from "plot_LR_v1.m" to "plot_LR_v5.m". The sophistication of the MATLAB programming increases from the first to the fifth file. Each is ~1 kB.

Problem set. The MATLAB script "computeLR.m" generates a plot of the concentration of ligand-receptor complex for different values of KD. This file can be used as a template to complete Part 1 of the Problem Set. The file "flash4.jpg" contains fluorescence data obtained using a confocal microscope and a custom-built system for spatially localized flash photolysis. These data are analyzed in Part 2 of the Problem Set.
