Change Details: In the version of this Perspective originally published, in the third paragraph of the section ‘Selection and sampling’, the sentence beginning ‘Pyrolysis–gas chromatography’ should have also referred to high-performance liquid chromatography; the sentence has now been amended to read ‘Pyrolysis–gas chromatography/mass spectrometry (py–GC/MS) and high-performance liquid chromatography (HPLC) can be used to detect the presence of amino acids<sup>62</sup> in any putative proteinaceous sample.’
