A new technique for separation of the CNBr cleavage products of collagen is described. It involves the use of a 30 nm pore reversed-phase high-performance liquid chromatography column eluted with a linear gradient of acetonitrile/water containing 0.01 M-heptafluorobutyric acid. The separation of type I, type II and type III CNBr peptides is described. Resolution is particularly good for the low-molecular-weight peptides. The method is fast, quantitative and sensitive, and the complete volatility of the eluent facilitates the recovery of the separated peptides.
本文描述了一种分离胶原蛋白溴化氰裂解产物的新技术。该技术使用孔径为30nm的反相高效液相色谱柱,以含0.01M七氟丁酸的乙腈/水线性梯度洗脱。文中介绍了I型、II型和III型溴化氰肽段的分离情况。对于低分子量肽段,分离效果尤其良好。该方法快速、定量且灵敏,洗脱液的完全挥发性有助于回收分离得到的肽段。
