Patent ID: 7241580

Claim:
A method of isolating, purifying, or concentrating a target compound, the method comprising: (a) conjugating the target compound to an epitope for a polyol-responsive monoclonal antibody (PR-mAb) to yield a conjugate, wherein the target compound is conjugated to an epitope consisting of the sequence selected from the group consisting of SLAELLNGLGGS (SEQ. ID. NO: 1). PTSPSYSPTSPSYS (SEQ. ID. NO: 2), TKDPSRVG (SEQ. ID. NO: 3) and TQDPSRVG (SEQ. ID. NO: 4); and then (b) contacting the conjugate of step (a) to an immunoaffinity matrix comprising a PR-mAb specifically reactive with the epitope of step (a).
