MacroCap SP, 5 L, Cytiva (CAT#: STEM-C-1577-LC)

MacroCap SP maufactured by Cytiva is a cation exchanger designed for the purification of large biomolecules such as polyethylene glycol (PEG)-modified proteins (i.e., PEGylated proteins) that are intended for use as biopharmaceuticals. It allows separation of mono- from oligo- and non-PEGylated proteins with high selectivity under high load conditions. MacroCap SP is based on acrylamide-dextran copolymer resins with mass transfer properties suitable for large biomolecules. The base matrix is highly porous, which offers high available surface area for adsorption of PEGylated proteins. The large pore size also makes MacroCap SP suitable for binding other large proteins, such as IgM. MacroCap SP is available in a range of different bulk pack sizes and convenient pre-packed formats for easy scale-up and process development. MacroCap SP meets industrial demands with security of supply and comprehensive technical and regulatory support.
