Abstract

Methods for determining whether a biological macromolecule binds to a compound are disclosed. The methods include: a) obtaining a Fourier-Transform Infrared spectrum of a solution which contains a biological macromolecule and obtaining a Fourier-Transform Infrared spectrum of a solution which includes a compound; b) obtaining a Fourier-Transform Infrared spectrum of a solution which contains the biological macromolecule and compound of step a); c) subtracting the Fourier-Transform Infrared spectrum of the biological macromolecule of step a) and the Fourier-Transform Infrared spectrum of the compound of step a) from the Fourier-Transform spectrum of step b) to determine a subtracted index; and d) determining that the compound of step a) binds to the biological macromolecule of step a) when the subtracted index of step c) is not equal to zero.
