CellMosaic’s size exclusion chromatography (SEC) HPLC LMW protein standard is designed for day to day use to check HPLC column performance and for the analysis of bioconjugates. The kit consists of four proteins with a MW range of 6.5 to 43 KDa and a small molecule with MW of 154 Da. The broad range of protein molecular weight coverage allows easy identification of small molecules, conjugates, and aggregates in a bioconjugation mixture, such as protein and peptide labeling and conjugation. CellMosaic routinely uses this product for its internal bioconjugation-related research.nnA total of two micro-centrifuge tubes are in a package. Each micro-centrifuge tube contains protein mixture lyophilized from 100 µL of standard solution. The product is ready for use after reconstituting in 100 µL of deionized water.nnShipping policy: heat-sensitive, choose overnight (ships Mon.-Thur.)
