变异链球菌6715野生型的突变体C307已被证明具有少量的兰斯菲尔德或Rantz-Randall可提取的血清型抗原。定量分析采用联合免疫吸附和放射免疫扩散的抗S。变形链球菌G型特异性血清表明，C307表现出低于S. mutans 6715野生型。
A mutant of Streptococcus mutans 6715 wild type designated C307 has been shown to possess a small amount of either Lancefield- or Rantz-Randall-extractable serotype antigen. Quantitative analysis employing combined immunoabsorption and radial immunodiffusion of anti-S. mutans serotype-specific serum demonstrated that C307 exhibited less than 1% of the amount of serotype g antigen normally expressed in S. mutans 6715 wild type.
