title: Sequence of human beta 2-microglobulin: a correction.
abstract: A tryptic peptide isolated from human urinary beta 2-microglobulin (beta 2m++) has has a composition that does not correspond to the published sequence. Automated sequence analysis confirms that the published sequence contains an error, an additional serine residue at position 67. In fact, human beta 2m has 99 residues, like the rabbit and mouse homologues.
