In this two-part monograph, the author describes modern methods for the rapid column liquid chromatography of high- and medium-molecular-weight compounds of biological origin, i.e. proteins, peptides, enzymes, nucleic acids, poly- and oligonucleotides, poly- and oligosaccharides, complex biopolymers and biooligomers such as viruses, bacteriophages, ribosomes and glycoconjugates, as well as some other compounds such as immunomodulators. The material is contained in two parts: Part A dealing with general chromatographic theory, principles, materials and techniques; and Part B dealing with the se.
