单链可变区片段(Single-chain variable domain fragment,scFv)637是重症肌无力的抗原特异性scFv。本研究将单链抗体与人血清白蛋白基因偶联,并在毕赤酵母中表达融合蛋白。免疫荧光法检测scFv-人血清白蛋白融合蛋白与人肋间肌神经肌肉接头处乙酰胆碱受体的结合能力。用竞争性ELISA法检测融合蛋白对重症肌无力患者血清乙酰胆碱受体结合的阻断能力及其在健康血清中的稳定性。结果表明,融合蛋白对大肠杆菌的抑制率为2.0- 77.4%,在静止的健康血清中稳定性约为3天。该方法表明scFv-人血清白蛋白是重症肌无力特异性免疫抑制治疗的潜在候选物。
Single-chain variable domain fragment (scFv) 637 is an antigen-specific scFv of myasthenia gravis. In this study, scFv and human serum albumin genes were conjugated and the fusion protein was expressed in Pichia pastoris. The affinity of scFv-human serum albumin fusion protein to bind to acetylcholine receptor at the neuromuscular junction of human intercostal muscles was detected by immunofluorescence staining. The ability of the fusion protein to block myasthenia gravis patient sera binding to acetylcholine receptors and its stability in healthy serum were measured by competitive ELISA. The results showed that the inhibition rate was 2.0-77.4%, and the stability of fusion protein in static healthy sera was about 3 days. This approach suggests the scFv-human serum albumin is a potential candidate for specific immunosuppressive therapy of myasthenia gravis.
