Qualitative and quantitative analysis of amino acids and proteins:
- analysis spectra of proteins and amino acid identity with amino acids, ultraviolet absorbing, in the fourth method derivatives;
- analysis of non-protein constituents in complex proteins such as porphyrins, copper ions, and other coenzymes;
- a quantitative method for assessing the Lowry protein content in the sample bound to different standards (bovine serum albumin, etc.). Calibration experiments were calculated by linear regression;
- a quantitative method for assessing the Bradford protein content of the sample;
- other colorimetric methods for the determination of protein content: biuret in different modifications, Lowry in different modifications, Onishi and Baer method and others;
- dual-wavelength quantitative methods for assessing the concentration of protein in the complex multi-component mixtures: Warburg and Christian, Erismann, Kalb and Bernlora, Viteykera and Granum.
Spectrophotometric method can also analyze samples of nucleic acids and their components.
