Some materials that have been analyzed crystallographically, such as proteins, do not occur naturally as crystals. Typically, such molecules are placed in solution and allowed to slowly crystallize through vapor diffusion. A drop of solution containing the molecule, buffer, and precipitants is sealed in a container with a reservoir containing a hygroscopic solution. Water in the drop diffuses to the reservoir, slowly increasing the concentration and allowing a crystal to form… tjma2grauWebX-ray crystallography is an imaging technique first described in 1913 by the father-and-son duo of William Henry Bragg (1862–1942) and William Lawrence Bragg (1890–1971), in … tjma 2 grau maWeb2 Likes, 0 Comments - Helix Biostructures, LLC (@helixbiostructures) on Instagram: "Yay!
