Which substance would make a good ligand for biotin on the matrix of an affinity chromatography column?

Question

Quizplus · Accepted Answer

Biotin is a vitamin that binds specifically to avidin through non-covalent interactions. Therefore, avidin would make a good ligand for biotin on the matrix of an affinity chromatography column. Choice A, ubiquinone, and choice C, oxaloacetate, do not have a known or specific affinity for biotin. Choice D, any molecule with an -SH group, may have some non-specific binding to biotin, but it does not have the same high specificity as avidin.
