Co-purification

An interaction is inferred from the identification of two or more protein subunits in a purified protein complex, as obtained by classical biochemical fractionation or affinity purification and one or more additional fractionation steps.

Interaction between prealbumin and retinol-binding protein studied by affinity chromatography, gel filtration and two-phase partition.

Fex G, Albertsson PA, Hansson B

The interaction between prealbumin and apo or holo retinol-binding proteins has been studied by affinity chromatography, gel filtration and two-phase partition. At physiological ionic strength apo and holo retinol-binding protein form 1:1 molar complexes with prealbumin. Mean dissociation constants for the prealbumin compex with apo retinol-binding protein and holo retinol-binding protein with all-trans retinol, retinoic acid, retinal and retinyl acetate ... [more]

An interaction is inferred when a bait protein, tagged with luciferase, is enzymatically detected in immunoprecipitates of the prey protein as light emission. The prey protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag.
