Dialysis and Desalting
Sigma Aldrich Fine Chemicals Biosciences HiTrapR IEX Selection Kit
HiTrap(R) IEX Selection Kit consists of seven HiTrap(R) columns prepacked with different Sepharose(R) fast flow ion exchange chromatography media for screening of the most appropriate media and conditions to use for specific application and development work.Q SP DEAE and CM Sepharose(R) fast flow are based on a robust 6% highly cross-linked beaded agarose matrix with good flow properties and high loading capacities. ANX Sepharose(R) 4 fast flow (high sub) is based on 4% highly cross-linked beaded agarose. This results in a medium with higher porosity which is particularly useful for the purification of high molecular mass proteins.Q and SP Sepharose(R) XL media have long chains of dextran coupled to a robust 6% highly cross-linked agarose matrix. The dextran chains increase the exposure of the Q or SP charged groups which results in very high loading capacities. The active end of the charged group is the same for DEAE Sepharose fast flow and ANX Sepharose(R) fast flow (high sub
Thermo Scientific™ Slide-A-Lyzer™ Dialysis Cassettes, 3.5K MWCO
