Research Abstract

In this study, we successfully crystallized three proteins in Mebiol gel. Our analysis indicates that Mebiol gel provides new possibilities for overcoming the inherent problem of high-temperature damage to the proteins. We also investigated the nucleation rate of protein crystals in the presence of Mebiol gel and found that Mebiol gel increased the number of protein crystals. Furthermore, the Mebiol gel surrounding the crystals reduces the influence of osmotic shock in high-ionic-strength solutions. This technique will open up a new dimension for the crystallization of biological macromolecules in hydrogels.
