多肽的基本常识

盐。 　　如果多肽在水中的溶解性有限，有几种选择可帮助溶解： 　　对碱性肽用稀乙酸（含Arg , Lys , His） 　　酸性肽用稀氨水（含Asp, Glu） 　　对极疏水的肽用10%有机修饰物（Acetonitnile , Methanol） 　　极不溶的肽用DM50或DMF 　　guanicline hydrochloride或脲的浓溶液也很有用， 与上述方法合用， 声处理也是溶解多肽的有效手段。 多肽的包装 　　目录中所有多肽除特别说明外，纯度为95~98

Disulfide Conjugation of Peptides to Oligonucleotides and Their Analogs

may have advantages for cell delivery, since it is likely to be cleaved within cells, thus releasing the oligonucleotide cargo. It is straightforward to introduce thiol functionalities into both oligonucleotide and peptide components suitable for disulfide conjugation

蛋白质组学指南

are separated and purified by reverse-phase HPLC or thin-layer chromatography (TLC) (Fig. 14). The isolated peptides are then cross-linked via their C termini to an inertmembrane (e.g. Immobilon P; PerSeptive Biosystems). The radioactive membrane is subjected
