時、微生物は上記器具に固相化されにくく、ブランクが
高い、感度が悪いという問題点かある。[Problems to be solved by the invention] However, when the antigen is a microorganism such as bacteria, fungi, or protozoa, the microorganism is difficult to immobilize on the above-mentioned instrument, resulting in problems such as high blanking and poor sensitivity. .
そこで従来、検体中の微生物に対する抗体価を測定する

液を用いた凝集反応法が採用されている。凝集反応法は
、酵素免疫測定法に比較し、感度的に劣る、擬反応が起
こり易い、光学的測定か困難等の欠点を有している。Therefore, conventionally, when measuring the antibody titer against microorganisms in a specimen, an agglutination reaction method using a microorganism suspension has been adopted, instead of an enzyme immunoassay method. The agglutination reaction method has disadvantages compared to the enzyme immunoassay method, such as being inferior in sensitivity, prone to false reactions, and difficult to perform optical measurements.
従って、前記器具に微生物を効率的に固相化てきるので
あれば、検体中の微生物に対する抗体価の測定を、凝集
反応法よりも優れた酵素免疫測定法を利用して行なうこ
とができる。Therefore, if the microorganisms can be efficiently immobilized on the device, the antibody titer against the microorganisms in the specimen can be measured using the enzyme immunoassay method, which is superior to the agglutination reaction method.
本発明は、抗原−抗体反応を行なう器具の表面に微生物

し\ 。■In the enzyme immunoassay method, the instruments such as microplates, beads, test tubes, etc. for immobilizing antigens and carrying out reactions are usually made of molded plastic, mainly polystyrene. These devices have the property of adsorbing proteins on their surfaces. On the other hand, microorganisms such as bacteria, fungi, and protozoa are covered with a cell wall made of polysaccharide, so they do not adsorb to the surface of these devices or are difficult to adhere to.

率良く固相化てきる。Therefore, in the present invention, first, a polymer having the property of adsorbing to the surface of the device (which has free amino groups that have chemical bonding properties with a crosslinking agent) is adsorbed onto the surface of the device. Next, a crosslinking agent for crosslinking the polymer and the microorganism to be solidified was reacted. At this time,
One reactive group of the crosslinking agent binds to the free amino group of the polymer, while the other reactive group remains as a functional group. Therefore, when microorganisms are brought into contact, the remaining functional groups of the crosslinking agent react with the amino groups of the microorganisms, and as a result, the microorganisms are efficiently immobilized on the surface of the instrument.
