中文摘要：

采用多肽固相合成技术制备了寡肽序列RRRRRRRR（R8）。通过电喷雾电离质谱仪对序列的相对分子质量进行了表征。进一步通过琼脂糖凝胶电泳和细胞内吞实验考察寡肽序列在生物学研究方面的应用。本实验可以加深学生对有机化学、高分子化学及生物化学的理解与运用,培养学生分析问题和解决问题的综合能力。

英文摘要：

The oligopeptide R8 was synthesized through the solid phase peptide synthesis（SPPS）protocols, and the molecular weight was measured by MS- ESI. The biological application of R8 was investigated by agarose gel electrophoresis assay and endocytosis. Through this experiment, students can study and apply organic chemistry, polymer chemistry, and chemical biology, as well as develop their capability for analyzing and resolving problems.
