(57) Abstract: An object of the present invention is to provide an antibody useful for an immunological measurement based on the agglutination reaction of human serum amyloid A (SAA), which is a marker for inflammation and the like, and a use of this antibody. is there. The present invention provides a molecular weight of 10-4 by gel filtration. It is an antibody that recognizes a novel SAA having binding activity also to the SAA contained in the 0 kD fraction. The present invention also provides An immunological assay reagent for SAA, an immunological assay method, and a method for purifying SAA using this antibody are provided. [Effect] The present invention enables the measurement based on the immunological agglutination reaction of SAA with a new antibody having excellent binding activity. The antibody of the present invention has excellent titer against SAA, Not only can AA be specifically measured with high sensitivity, but it also contributes to the expansion of the measurement range. |
