Achromopeptidase (TBL-1; Wako Chemicals, USA, Inc., Dallas, Tex.) prepared as a 2,000-U/ml solution will extract the serogroup antigens from single colonies of groups A, B, C, F, and G streptococci in 1 min at room temperature. This enzyme extraction is not effective for the serogrouping of all group D streptococcus species. Achromopeptidase extracts can be used with latex or coagglutination reagents.
无色肽酶(TBL-1;和光纯药工业株式会社美国公司,得克萨斯州达拉斯)配制成2000 U/ml的溶液,在室温下1分钟内可从A、B、C、F和G群链球菌的单个菌落中提取血清群抗原。这种酶提取法对所有D群链球菌种的血清学分型无效。无色肽酶提取物可与乳胶或协同凝集试剂一起使用。
