We describe the Blue Native (BN)-PAGE retardation assay for the detection of interactions of biomolecules with protein complexes. Potential interactors of proteins are included in the BN gel matrix, resulting in retardation of proteins that interact with the added molecule. After validation using the T-cell antigen receptor, we applied the assay for a general identification of dextran interactors in combination with mass spectroscopy. The proteomic screen revealed triosephosphate isomerase oligomer as a dextran-binding, high MR complex.
