(57) Abstract: N 1 which is expected as a tumor marker, N 12 - to provide a measure of diacetylspermine. A sample is obtained by using an immunoreaction between immobilized or labeled N 1 , N 12 -diacetylspermine or immobilized or labeled N 1 -acetylspermine and an anti-NN 1 , N 12 -diacetylspermine monoclonal antibody. N 1 and N 12 inside -Measure diacetylspermine. At this time, the anti-NN 1 , N 12 − − in which the inhibitory activity of the immune response by N 1 , N 12 -diacetylspermine under the measurement conditions is 20 times or more the inhibitory activity of the immune response by N 1 -acetylspermidine. A measurement method using a diacetylspermine monoclonal antibody was found. |
