  • Process for affinity purification by immunoadsorption in non-aqueous solvent
    Patent number: 5364531
    Abstract: Immunoaffinity purifications are performed using non-aqueous media, desirably, a small amount of an aqueous buffered medium, and, optionally, a surfactant. Hydrophobic ligands can be extracted from samples, immunoaffinity purified and eluted to provide a substantially pure product.
    Type: Grant
