REAGENT FOR ASSAYING LAMININ 5 ANTIGEN IN BIOLOGICAL SAMPLE AND ASSAY METHOD

摘要

A method of determining a laminin 5 antigen in a biological sample, comprising the steps of bringing an antibody reactive to a laminin 5 gamma 2 chain N-terminal fragment into contact with the biological sample; measuring a reaction of the antibody; and determining an amount of the laminin 5 antigen based on a measurement result of the reaction, as well as, a method of detecting a laminin 5-producing tumor cell, a method of examining acute respiratory distress syndrome and a method of evaluating malignancy of a malignant tumor based on the assay method. <IMAGE>
