  • Leucocyte adherence inhibition assay for detection of cancer
    Patent number: 4426446
    Abstract: Methods for carrying the leucocyte adherence inhibition (LAI) assay for detecting the presence of cancer in responsive patients. One aspect of the invention utilizes incubation with agents which maximize the intracellular cycle 3',5'-adenosine monophosphate (cAMP) levels in the leucocytes as a means to expand the percentage of responding subjects in different cancers. A second aspect utilizes measurement of extracted, vital cell dye to avoid the need of counting the adhering or non-adhering leucocytes.
