Chromatographic column
First Claim
1. A chromatographic column having at least three resin layers between the inlet and the outlet ends of the column, the layer closest the inlet being a strong cationic exchange resin, the middle layer being a backbone containing a triazine dye that will bind proteases and proteins with dinucleotide fold conformations, and the layer closest to the outlet being a weak anionic exchange resin, the ratio of the volumes of the resin layers being 1:

Abstract
A chromatographic column and process for isolating or purifying steroid hormone or cell membrane receptors using the column are provided in which the column contains at least three resin layers between the inlet and the outlet ends of the column, the layer closest the inlet being a strong cationic exchange resin, the middle layer being a matrix containing a triazine dye that will bind proteases and proteins with dinucleotide fold conformations, and the layer closest the outlet being a weak anionic exchange resin, the ratio of the volumes of the resin layers being 1:2:1.
