[reaction: see text] DNA-peptide conjugates were synthesized by condensing partially protected peptide fragments and oligonucleotides on a CPG support using diisocyanatoalkane as a linker. After cleavage and deprotection with aqueous ammonia, pure products were obtained by single RPHPLC purification in satisfactory yields and identified by a MALDI-TOF MS spectrometer. This method allows one to prepare DNA-peptide conjugates with any components and sequences of DNA and peptides.
[反应:见正文] 使用二异氰酸酯烷烃作为连接体,通过在CPG载体上缩合部分保护的肽片段和寡核苷酸来合成DNA - 肽缀合物。用氨水进行切割和脱保护后,通过单次反相高效液相色谱(RPHPLC)纯化以令人满意的产率获得纯产物,并通过基质辅助激光解吸电离飞行时间质谱仪(MALDI - TOF MS)进行鉴定。该方法允许制备具有任何DNA和肽的组分及序列的DNA - 肽缀合物。
