Title: NONSPECIFIC REACTION INHIBITOR
Abstract:
The present invention addresses the problem of providing a nonspecific reaction inhibitor whereby nonspecific reaction due to a nonspecific factor can be adequately suppressed even for a specimen in which the effect of a heterophil antibody or other nonspecific factor could not be adequately suppressed by the conventional nonspecific reaction inhibitor. The present invention relates to a nonspecific reaction inhibitor for immunoassay, characterized by containing anti-mammal-derived IgM antibodies for which the ratio (A2/A1) of the absorbance A2 when reacted with feline IgM to the absorbance A1 when reacted with canine IgM is 0.1 to 1.5, and the ratio (A3/A1) of the absorbance A3 when reacted with human IgM to the absorbance A1 when reacted with canine IgM is 0.5 or greater.
