General description

Weak anion exchange Fractogel® resin featuring the tentacle technology, for purification of acidic and neutral proteins and peptides from multiple sources, pDNA purification, DNA, RNA, and endotoxin removal, large viruses purification, vaccine purification, blood fractionation, and more

Features and Benefits

Fractogel® EMD DEAE (M) enables:

  • Excellent binding to large viruses and plasmid DNA
  • Homogenous binding with high selectivity and purity
  • Lower elution volumes for the highest purity levels
  • Compatibility with 2.5 % (v/v) aqueous benzyl alcohol containing 150 mM NaCl storage solution


Due to the titration behavior, the ion exchange capacity can be used from pH 2 to pH 9.5. The separation of proteins is based on reversible electrostatic interactions between the negatively charged regions of the proteins′ surface and the support. Proteins are retained efficiently on Fractogel® EMD DEAE when the pH of the buffer is about 1 unit above their isoelectric points (pl).

The strength of the binding depends on the following:
  • the buffer system
  • pH value of the buffer which determines the surface charge of the protein
  • the degree of the ionization of the functional groups of the exchanger
  • the concentration of the counter ions
  • the charge density on the support (protein binding capacity)

A relatively templated manufacturing process can be used to produce live vector vaccines. Challenges exist, however, and include yield loss due to sterile filtration, vector aggregation and scaling adherent cultures. Learn all about this core platform technology and how expertise—empowered by collaboration— can overcome manufacturing challenges.

Manufacturing viral vaccines is complex and there is no templated approach. Each process must be tailored to the shape, size, nature, physico-chemical behavior, stability, and host specificity of the virus.
