Open the CIPO recordAbstract From the Canadian patent
Techniques for preparing stable conjugates of protein-?-GL which can then be isolated in pure form are disclosed, using hen egg ovalbumin (OVA) as a prototype protein, and conjugation and purification methods are described which involve 1) application of a coupling method employing m-maleimidobenzoyl-Nhydroxysuccinimide ester (MBS) as the coupling reagent, and 2) introduction of biotin moieties into ?-GL molecules to allow application of avidinbiotin system for affinity chromatographic purification of conjugates. These methods are applicable to the preparation of ?-GL conjugates of insulin and Ragweed Antigen E and are of general applicability.
