从混合物中分离、纯化或富集某些组分以获得相对纯物质是科学研究和生产实践的一项重要内容,而传统的化学分离方法如蒸馏、熔炼等,对具有特殊生物活性物质的分离是不适合的,许多生物活性物质如蛋白质、酶、核酸、细胞等必须借助生物分离技术才能够分离。一、纸层析法分离色素分离原理:各种色素在层析液中的溶解 The separation, purification or enrichment of certain components from mixtures to obtain relatively pure substances is an important part of scientific research and production practice, whereas traditional chemical separation methods such as distillation, smelting, etc., separate the specific bioactive substances Is not suitable, many of the bioactive substances such as proteins, enzymes, nucleic acids, cells, etc. must be separated by biological separation techniques. First, the paper chromatography separation Principle of pigment separation: a variety of pigments dissolved in the chromatographic solution
