Detection and quantitation of viral antibodies

摘要

Method of detecting and/or quantitating anti-virus antibodies comprising the steps of reacting serum containing an unknown amount of a given antibody, a known amount of the antibody (radioactively labelled), and a composite consisting of the antibodies coupled chemically through an intermediate silane coupling agent to a porous glass body, the composite having complexed thereto quantities of the virus; separating the composite from the reaction solution after a suitable reaction period; determining the radioactivity count of the separated composite or the remaining solution; and, relating the count to a standard curve.
