Luminescentoxygenchannelingassay(LOCITM): sensitive,broadlyapplicablehomogeneous immunoassaymethod

Luminescent oxygen channeling assay (LOCITM) is a ho- mogeneous immunoassay method capable of rapid, quanti- tative determination of a wide range of analytes-including high and very low concentrations of large and small mole- cules, free (unbound) drugs, DNA, and specific 1gM. Assays have been carried out in serum and in lysed blood. Reliable detection of 1.25 tUfL thyrotropin (TSH) and
