    摘要: The present invention features methods for purifying polypeptides of interest using a modified Fluorescein arsenical helix binder (FlAsH) compound immobilized on a solid support. An exemplary FlAsH target sequence motif is also presented. Examples of modification of the FlAsH compound which allow immobilization to a solid support are also provided. The present invention also provides DNA constructs for producing a dual affinity tagged polypeptide and methods for purification thereof.
