"Researchers used several different techniques to identify the presence of collagen. First, they found that antibodies to collagen would bind to the samples, and this binding did not occur after treatment with enzymes that specifically degrade collagen. Second, they used mass spectrometry to determine the amino acid sequence of the protein. They then mapped various protein fragments and compared them against a database of protein sequences from a variety of organisms."
