What is CE-SDS?

CE-SDS stands for Capillary Electrophoresis Sodium Dodecyl Sulfate. It's an analytical technique used primarily in the biopharmaceutical industry to characterize proteins. Specifically, it's used to determine protein purity, heterogeneity, and molecular weight. The technique involves separating proteins based on their size as they migrate through a capillary under an electric field. The proteins are denatured and coated with SDS, giving them a uniform charge-to-mass ratio, allowing for separation solely based on size.
