Immunoadsorbents were prepared by the use of an inorganic carrier. The proteins were covalently coupled to the carrier through a silane coupling agent. An immunoadsorbent prepared with human gamma-globulin was found to complex with specific antibodies. These antibodies could be recovered in high yield and purity from the adsorbent. Similarly, insolubilized antibodies to l-asparaginase were used to isolate and purify the enzyme from crude extracts. These insolubilized antibodies are extremely stable with time and may be reused many times.
使用无机载体制备免疫吸附剂。蛋白质通过硅烷偶联剂与载体共价偶联。发现用人γ-球蛋白制备的免疫吸附剂能与特异性抗体形成复合物。这些抗体可以从吸附剂中高产量、高纯度地回收。同样,用对L-天冬酰胺酶的固定化抗体从粗提物中分离和纯化该酶。这些固定化抗体随时间极其稳定,可多次重复使用。
