The agglutination for rabbit was the highest among erythrocytes of human, rabbit, common carp and crucian carp. The hemagglutinating activity for rabbit could not be inhibited by D-fructose, D-mannose, D-galactose, glucose, sucrose, manrmn, gamma-globulin and egg albumin, but inhibited by bovine-thyroglobulin, and the minimum inhibitory concentration was 3.10 mg/ml.
该凝集素可以凝集人的A、B、AB、O型红细胞，且凝集活性相同，在对人、兔、鲤、鲫的红细胞的凝集作用中，对兔红细胞的凝集作用最强，且不被己测试的D-半乳糖、D-果糖、D-甘露糖、葡萄糖、蔗糖、甘露聚糖、γ-球蛋白、卵清蛋白所抑制，仅被牛甲状腺球蛋白抑制，最小抑制质量浪度为3.10mg/ml。
