WebbThe PCT Pre-Crystallization Test is used to determine the appropriate protein concentration for crystallization screening. Sample concentration is a significant crystallization variable. Samples too concentrated can result in amorphous precipitate, while samples too dilute can result in clear drops. Webb1 jan. 2014 · The most common techniques for protein crystallization fall under the general category of crystallization by vapor diffusion [ 2, 4, 12 ]. In this approach a droplet of purified protein sample is mixed with crystallization solution and is equilibrated against a larger reservoir of the same solution in a sealed crystallization chamber. rice university gas hydrate professor https://bioanalyticalsolutions.net
