Streptococcal M protein-sensitized sheep red blood cells stored in liquid nitrogen showed insignificant change in titer when tested against homologous antisera over a 6-month period. This method eliminates much of the preparation time required for the passive hemagglutination procedure and increases the reproducibility of the test.
储存在液氮中的链球菌M蛋白致敏绵羊红细胞,在6个月的时间里,用同源抗血清检测时,其滴度变化不显著。这种方法省去了被动血凝试验所需的大量准备时间,并提高了检测的可重复性。
