IRMA kits

Our immunoradiometric diagnostic kits (IRMA) are intended for the quantitation of certain serum proteins, in particular hormones and tumour markers. IRMA kits contain two monoclonal antibodies raised against different epitopes on the protein molecule. One is bound to a solid phase and the other is labelled with radioactive iodine. During analysis they form a sandwich round the analyte in proportion to its concentration.
