Affinity Chromatography

Agarose & PS-DVB(Poly(styrene/divinylbenzene) Substrate

affinity agarose base

Agarose Substrate 45-135μm

  • High cross-linked agarose
  • Good water-swellable
  • Super biological compatibility
  • Alkali resistance, 0.1-0.5M NaOH CIP
Protein A Affinity Resin sepromax A40

PS-DVB Substrate 40μm

  • Hydrophobic PSDVB particles
  • Super rigidity, low back pressure
  • Excellent dynamic binding capacity
  • Alkali resistance, 0.1-0.5M NaOH CIP

Recombinant Protein A/G Ligand

The recombinant Protein A/G consists of 7 IgG-binding domains EDABC-C2C3, which corresponds to the Protein A and G domains that are included in the recombinant sequence. The Protein A portion is from Staphylococcus aureus segments E, D, A, B and C. The Protein G portion is from Streptococcus segments C2 and C3. The fusion protein has a predicted molecular mass of 50.5 kDa. But it migrates with an apparent molecular mass of approximately 45kDa in SDS-PAGE.
