1944～1945年间,与作者同在剑桥大学病理室工作的动物免疫学家Coombs对不完全抗体的性质发生了兴趣。他用显微镜观察悬浮在盐水介质中用完全和不完全抗体致敏的红细胞在电场内的游走现象,并用未致敏的细胞作对照。他发现用完全和不完全抗体致敏细胞的游走速度相近,与未致敏细胞区别很大。1945年7月Taylor去世后,由Race接任负责人。作者当时刚进入这个室,职位较低。和作者几乎同时来的Coombs提出了抗球蛋白试验原理。他声称他那时正待在一列偶然发生故障的从伦敦到剑桥的战时列车 Between 1944 and 1945, Coombs, an animal immunologist working with the author in the University of Cambridge Department of Pathology, became interested in the properties of an imperfect antibody. He used a microscope to observe the wandering of erythrocytes that were sensitized with both intact and incomplete antibodies suspended in saline, in an electric field, and used non-sensitized cells as a control. He found that the sensitized cells with complete and incomplete antibody migration speed similar to non-sensitized cells very different. After Taylor died in July 1945, Race took the helm. The author just entered the room at that time, with a lower position. Coombs, who came almost simultaneously with the author, presented the antiglobulin test principle. He claimed that he was waiting for a time-bound war train from London to Cambridge at that time
