This work presents a unique method for the visible detection of site-specific molecular interactions between proteins and small molecules. In this method, a silica thin-film, which shows thin-film interference, was used as a substrate. On its surface, protein multilayers made up of avidin- and dethiobiotin-labeled bovine serum albumin (BSA) were constructed via the avidin-dethiobiotin bond. Film construction behaviors were confirmed visibly owing to the uniform change of the interference color. This multilayer was able to disassemble by biotin addition, taking advantage of the higher association constant of avidin-biotin bonding. Disassembling of the multilayer was also confirmable as a drastic color change seen by the naked eye. The Royal Society of Chemistry.

, (2022/03/02)
Methods for purifying biological macromolecules are provided. Aspects of the subject methods include contacting the biological macromolecule with an exemplary hydroxamate affinity tag to produce a tagged moiety followed by purification of the tagged moiety by immobilized metal affinity chromatography (IMAC). Also provided are kits comprising an exemplary subject hydroxamate affinity tag, an IMAC resin and a metal ion configured for loading onto the resin, wherein the metal ion is capable of binding to a compound containing the hydroxamate affinity tag.
