Abstract

Poor immunogenicity of small proteins is a major hurdle in developing vaccines or producing antibodies for biopharmaceutical usage. Here, we systematically analyzed the effects of 10 solubility controlling peptide tags (SCP-tags) on the immunogenicity of a non-immunogenic model protein, bovine pancreatic trypsin inhibitor (BPTI-19A; 6 kDa). CD, fluorescence, DLS, SLS, and AUC measurements indicated that the SCP-tags did not change the secondary structure content nor the tertiary structures of the protein nor its monomeric state. ELISA results indicated that the 5-proline (C5P) and 5-arginine (C5R) tags unexpectedly increased the IgG level of BPTI-19A by 240- and 73-fold, respectively, suggesting that non-oligomerizing SCP-tags may provide a novel method for increasing the immunogenicity of a protein in a highly specific manner.

摘要

小蛋白的免疫原性差是开发疫苗或生产用于生物制药的抗体的主要障碍。在这里,我们系统地分析了 10 种可溶性控制肽标签(SCP-tags)对一种非免疫原性模型蛋白(牛胰蛋白酶抑制剂(BPTI-19A;6 kDa))的免疫原性的影响。圆二色性(CD)、荧光、动态光散射(DLS)、小角激光散射(SLS)和 AUC 测量表明,SCP-tags 不会改变蛋白质的二级结构含量和三级结构,也不会改变其单体状态。ELISA 结果表明,5-脯氨酸(C5P)和 5-精氨酸(C5R)标签出人意料地分别将 BPTI-19A 的 IgG 水平提高了 240 倍和 73 倍,这表明非寡聚 SCP-tags 可能提供了一种新的方法,以高度特异性的方式提高蛋白质的免疫原性。
