Abstract
The STP polysaccharide was isolated from an aqueous extract of Solanum tuberosum L. and purified by ion exchange chromatography and gel filtration. Its molecular mass was determined by gel-penetrating chromatography and high-performance liquid chromatography, and its monosaccharide composition was analyzed by high-performance liquid chromatography and gas chromatography using a flame ionization detector and a capillary column. It was shown that STP polysaccharide consists of galactose and arabinose at 37.5% and 23.5%, respectively, as well as uronic acids (9.7%), glucose monosaccharide residues (15%), and proteins (at least 9%). The molecular mass of STP is 70 kDa. The method of IR-Fourier spectroscopy was used for the structural analysis of STP. The mitogenic activity of the extracted polysaccharide was comparable to the activity of lipopolysaccharide.

期刊介绍：
Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
