Humoral proteins from Amphioxus lanceolatus showed a considerable agglutinating activity for human red cells. The haemagglutinating factor eluted in the macroglobulin peak on Sephadex G200 and resulted ConA-1 at affinity chromatography on Sepharose ConA. Immunoelectrophoresis, carried out using a specific antiserum produced in rabbit, revealed alpha mobility for the agglutinating factor, thus suggesting that it was an alpha macroglobulin.
文昌鱼的体液蛋白对人类红细胞表现出相当强的凝集活性。在Sephadex G200上，血凝因子在巨球蛋白峰处洗脱，在ConA琼脂糖亲和层析中得到ConA-1。使用兔产生的特异性抗血清进行免疫电泳，显示凝集因子具有α迁移率，因此表明它是一种α巨球蛋白。
