CrystalsFirst - Crystal-Grade Proteins

CrystalsFirst provides crystal-grade proteins from any of the major expression systems, such as bacteria, insect, or mammalian cell lines.Thanks to our state-of-the-art technologies the production process is customized for every need, from mgs to tens of mgs scale. Our quality control ensures the high-quality of the protein material for crystallographic purposes. Methods such as mass spectrometry (MS), analytical size-exclusion chromatography (SEC), circular dichroism (CD), dynamic light scattering (DLS), and thermal shift assay (TSA) are applied routinely to ensure high-quality of protein material for crystallography.
