An assay device comprising an array of non-nucleic acid molecules for detection of a binding partner in a biological sample

摘要

Described is a method using an assay device that can identify a type of leukaemia in a human biological sample containing CD antigens. The sample is contacted with an array of immunoglobulin molecules. Each immunoglobulin in the array, with the exception of one or more negative controls, is capable of interaction with a CD antigen on one or more types of leukaemia cells. The pattern of interaction between the immunoglobulin molecules and the CD antigens in the sample is then determined, thereby providing an immunophenotype of the cells, which is characteristic of the type of leukaemia.
