Abstract
A glycoprotein fraction, by which the 32P-releasing activity of serum on labelled E. coli is lowered, was isolated from caecum content of germfree rats. The glycoprotein contained 83.1% sulphate, and 16.1% protein. The molecular weight ranged from 3.2 X 10(5) to 2.4 X 10(6), and the iso-electric point from pH 0.9 to 3.0. Physiologically, it may play a role in the interaction(s) between the host and its intestinal flora.
摘要
从无菌大鼠的盲肠内容物中分离出一种糖蛋白组分，该组分可降低血清对标记大肠杆菌的³²P释放活性。这种糖蛋白含有83.1%的硫酸盐和16.1%的蛋白质。分子量范围为3.2×10⁵至2.4×10⁶，等电点为pH 0.9至3.0。在生理上，它可能在宿主与其肠道菌群之间的相互作用中发挥作用。
