title: Mixtures of porcine and bovine insulin analysed by fast atom bombardment mass spectrometry with selected ion monitoring.
abstract: Mixtures of bovine and porcine insulin have been analysed by fast atom bombardment mass spectrometry with selected ion monitoring of M + H ions at m/z 5733.9 (bovine) and 5778.0 (porcine). Porcine insulin could be detected in a mixture of 2% porcine and 98% bovine insulin and with bovine insulin as the minor component as little as 1% could be detected.
