  • Title: Identification of polyol-responsive monoclonal antibodies for use in immunoaffinity chromatography.
    Author: Thompson NE, Burgess RR.
    Journal: Curr Protoc Mol Biol; 2001 May; Chapter 11():Unit11.18. PubMed ID: 18265073.
    Abstract:
    One of the limitations of immunoaffinity chromatography as been that high-affinity antigen-antibody complexes are difficult to dissociate, often leading to inactivation of the protein product during elution from the immobilized antibody. As described in this unit, some antigen-antibody complexes can be dissociated in the presence of a combination of a low-molecular-weight polyhydroxylated compound (polyol) and a nonchaotropic salt. These conditions seem to be generally nondenaturing and, in some cases, even protein-stabilizing. This type of antibody is designated "polyol-responsive." These antibodies can be easily identified and isolated as monoclonal antibodies (MAbs) from a typical fusion, using standard hybridoma procedures. They have proven to be very valuable reagents for the immunoaffinity purification of active, labile, multi-subunit protein complexes.
