The misidentification of a protein sample, or contamination of a sample with the wrong protein, may be a potential reason for the non-reproducibility of experiments. This problem may occur in the process of heterologous overexpression and purification of recombinant proteins, as well as purification of proteins from natural sources.

Webb5 aug. 2009 · In general, the crystallization has many advantages over other purification methods (chromatography and precipitation): high recovery of product (>90%), low reagent costs, inexpensive process equipment, small process volumes and high purification in a single process step [2]. WebbThe procedure consists, approximately, of the following aspects: A few microliters (1-2 μl) of protein solution are mixed with a more or less equal amount of reservoir solution containing the precipitants (previously balanced with a pH buffer) and are deposited on a cover slip which covers the precipitant reservoir. As the protein/precipitant mixture in the …
