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
