Identification and quantification of feathers, down, and hair of avian and mammalian origin using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry

, : Identification and quantification of feathers, down, and hair of avian and mammalian origin using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Analytical Chemistry Washington 74(23): 5960-5968

We describe a fast method for the identification of the origin of native and chemically processed feathers, down, and hair and for distinguishing closely related species using enzyme digestion and MALDI-TOF mass spectrometry. Additionally we present two methods for the quantification of different identified bird and mammalian samples, respectively, in binary species mixtures.
