Conventional methods for the propagation and preservation of parasites in vivo or in vitro have limitations, which include the need for labor, the initial isolation and loss of strains, bacterial and fungal contamination, and changes in the original biological and metabolic characteristics of the organism. All of these disadvantages are reduced considerably by cryopreservation. In this study, w...

The three-dimensional structure of protein is determined by analyzing diffraction data collected using X-ray beams. However, beam can damage crystals during collection, lowering the quality crystal data. A way to prevent such treating with cryoprotectants. cryoprotectant stabilizes and prevents Many kinds cryoprotectants are commercially available, various treatment methods have also been repor...
