High-quality recombinant proteins
CrystalsFirst provides crystal-grade proteins from any of the major expression systems, such as bacteria, insect, or mammalian cell lines. The production process is customized for 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.
