This chapter describes the construction and screening of a library of single-chain variable fragments (svFv) derived from patients with autoimmune disease. The methods cover the isolation of mononuclear cells from peripheral blood, preparation of RNA, and recovery of immunoglobulin-coding sequences by polymerase chain reaction (PCR). Cloning into a phage display vector and screening of the scFv display library by a simple panning procedure are described. These methods are applicable to library construction from any patient group or (with alternative primer sets) any mammalian species.
本章描述了从自身免疫性疾病患者中获得的单链可变片段(scFv)文库的构建和筛选方法。这些方法包括从外周血中分离单核细胞、制备RNA以及通过聚合酶链反应(PCR)回收免疫球蛋白编码序列。还介绍了将其克隆到噬菌体展示载体中,并通过简单的淘选程序筛选scFv展示文库的方法。这些方法适用于从任何患者群体构建文库,或(使用替代引物组)从任何哺乳动物物种构建文库。
