comparison with the fluorescence spectrum of the bovine brain s100-a ' protein ( alpha'beta ) , which contains a tryptophan residue in the alpha ' subunit , enables us to demonstrate that the recent report describing an abnormal fluorescence spectrum for the bovine brain s100-b protein may result from a contamination of the s100-b by the s100-a ' protein .
