Lepta DEAE HR is a new type of highly cross-linked agarose anion exchange resin, which has high flow rate, low back pressure, high dynamic load, good chemical stability and mechanical properties, low non-specific adsorption, high recovery rate, convenient scale-up, and can shorten production time and improve production efficiency. It is widely used in the ion exchange separation of downstream proteins, nucleic acids and peptides in biopharmaceuticals and bioengineering.
