Biomolecules can be immobilized by binding them to a support under conditions that will then determine the characteristics of the complex. Immobilization is a technique that binds a ligand (enzyme, antibody, affinity proteins like Protein A or Protein G) to a support, giving high stability and making it easier to reuse the immobilized molecule.
Aminoethyl resin give the biomolecules increased stability through the covalent bonds of the agarose to carboxy group amino acids of the target ligand, thus facilitating recovery and later reuse. This covalent binding also confers a qualitative advantage compared to resins activated with CNBr, in which the binding is weaker.
The choice of Glyoxal or Aminoethyl will depend on the biomolecule to be immobilized, the accessibility of the reactive groups, and the direction/ orientation required for the binding to the support.
Storage/Handling: Store at 4°C. Do not freeze.
