Catch as catch can. Fmoc-SPPS α-GalNAc-, β-GlcNAc- and α-GlcNAc-O-Tyr amino acid building blocks were prepared and applied in synthesis of glycopeptide vaccine constructs and an extensive Tyr-modified glycopeptide library. Antibodies were raised and affinity purified against the antigen peptides. Evaluation by ELISA, glycopeptide microarrays and by western blot analysis showed high antibody specificity
尽可能地抓住。制备了Fmoc-
SPPS α-GalNAc-、β-GlcNAc- 和 α-GlcNAc- O -Tyr
氨基酸结构单元,并将其应用于糖肽疫苗构建体和广泛的 Tyr 修饰糖肽文库的合成。针对抗原肽产生
抗体并进行亲和纯化。通过 ELI
SA、糖肽微阵列和蛋白质印迹分析进行的评估显示,
抗体对 GalNAc- 和 GlcNAc- O -Tyr 修饰具有高度特异性,与相应的 Ser 或 Thr 糖肽没有交叉反应。
