Fractionation by size (molecular weight) is an effective enrichment strategy for studies of protein families and posttranslational modifications, because the sizes of these proteins tend to be similar.The Model 491 prep cells separate biomolecules quickly and efficiently by continuous-elution electrophoresis. Samples are electrophoresed through a cylindrical gel matrix, where they are separated into ring-shaped bands. As individual bands migrate off the bottom of the gel, they are collected in discrete liquid fractions available for assay and characterization.The Model 491 prep cell:Allow resolution of proteins differing in molecular weight by as little as 2%Separate up to 500 mg of total proteinCan be used as a complementary separation strategy to 2-D gels as well as for downstream protein purificationThe Model 491 prep cell has a sample capacity of 1–500 mg/0.5–15 ml.Accessory equipment required to run the Model 491 includes a fraction collector and power supply such as the PowerPac HV power supply. This sale includes a Model 491 prep cell variable speed peristaltic pump.
