Biopolymers for Biomedical Applications

Gel-B (dry content 91.3%, Mw = 209,600 g·mol ${}^{-1}$ ) and Gel-R (dry content 86.5%, Mw = 157,800 g·mol ${}^{-1}$ ) were obtained from Tanex Vladislav, a.s. Gel-C (dry content 92.7%, Mw = 190,900 g·mol ${}^{-1}$ ) was prepared according to a patented biotechnological process [37 ], which is described in detail in Mokrejš et al., 2019 [38 (link)] and Gál et al., 2020 [39 (link)]. Dextran (Dex) Mw = 40,400 g·mol ${}^{-1}$ , sodium periodate, and phosphate-buffered saline sterile solution (PBS), pH 7.4, were obtained from Sigma Aldrich. Demineralized (DEMI) water was prepared using Milipore Q System. Ammonia solution, 30 vol% was purchased from Penta and diluted to 25 vol%. Na ${}_2$ HPO ${}_4$ .12H ${}_2$ O and NaH ${}_2$ PO ${}_4$ .2H ${}_2$ O, used for the preparation of PBS pH 7, were obtained form Lach-Ner.
