Introduction
In the previous laboratory session you screened SMM slides using your purified FKBP12 protein. To identify which of the small molecules you screened bind FKBP12, your slides will be evaluated using a Genepix microarray scanner. The scanner will measure the fluorescence signal emitted from each spot on the slide where a ligand was printed. Considering that neither the ligands nor FKBP12 protein is fluorescent, from where does this signal arise?
