By a radiometric method using C14 labelled amino acid mixture it was established that the Streptococcus pyogenes A49 L-forms cells invade tissue cultures MK and F in a similar degree as parent bacterium cells. The L-form cells are not able to enter the HeLa and Pulmo tissue culture cells but the parent bacterium cells produce well expressed peak of isotope take-up at the 8th hour of the observation.
通过使用C14标记氨基酸混合物的放射性测量方法确定，化脓性链球菌A49 L型细胞侵袭组织培养物MK和F的程度与亲代细菌细胞相似。L型细胞无法进入HeLa和Pulmo组织培养细胞，但亲代细菌细胞在观察的第8小时产生表达良好的同位素摄取峰值。
