Bovine pituitary IgM was isolated from anterior lobe material by molecular sieve and DEAE-cellulose chromatography. It was characterized using physico-chemical and immunochemical techniques. The molecular weight of the molecule was below 20 000, and immunoelectrophoretic and immunodiffusion analysis, demonstrated precipitin arcs for IgM. The small molecular weight protein may prove to be significant in continuing studies of IgM and the relationship of the pituitary gland to the immune system.
牛垂体IgM通过分子筛和DEAE-纤维素色谱法从前叶材料中分离出来。使用物理化学和免疫化学技术对其进行了表征。该分子的分子量低于20000，免疫电泳和免疫扩散分析显示出IgM的沉淀弧。这种小分子蛋白可能在IgM的持续研究以及垂体与免疫系统的关系研究中具有重要意义。
