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.
从人尿β2-微球蛋白（β2m++）中分离出的一种胰蛋白酶肽段，其组成与已发表的序列不符。自动序列分析证实已发表的序列存在错误，在第67位有一个额外的丝氨酸残基。事实上，人β2m有99个残基，与兔和小鼠的同源物一样。
