E. coli Protein (Agarose) 4B, 1 ML

Price$ 173.75
  • SKU: E-3349-1ML
  • Pack Size: 1 ML



Provides immobilized E. coli proteins on a solid bio-affinity support for the removal of antibodies to E. coli proteins from antisera prepared against recombinant proteins expressed in E. coli. Our immobilized E. coli lysate consists of partially purified proteins from E. coli strains commonly used for protein expression. The coupling chemistry is leak-resistant and provides a matrix with very low nonspecific binding. A column of immobilized E. coli lysate thus functions as a "reverse affinity matrix". The contaminating E. coli antibodies are absorbed onto the matrix and the purified antisera passes through for further use.


Technical specifications:

  • Ligand: E. coli proteins that are extracted from three strains
  • Matrix: 4B (agarose beads, 4 %)
  • Particle size range: 52 – 165 µm
  • Molecular weight range: 6 x 104 - 2 x 107
  • Matrix activation: Cyanogen bromide
  • pH stability: 4 – 9
  • Storage temp: 4 °C in the presence of sodium azide
  • Supplied as settled gel in PBS containing sodium azide
