In this work, we establish that cocaine binding to the Fab fragment of a recombinant humanized anti-cocaine mAb (h2E2) can be directly and easily quantitated using simple and inexpensive absorption and fluorescence measurements, employing dyes typically used for differential scanning fluorimetry, DASPMI and SYPRO Orange. For concentrated samples of the Fab fragment, absorbance spectroscopy employing these dyes reveals the number of cocaine sites present, using either DASPMI (by measuring the increase in dye absorbance) or SYPRO
