"[0210] When the cancer cell-specific anti-podocalyxin antibody is bound to latex particles and mixed with a sample, the antibody-bound latex particles aggregate in the presence of cancer specific podocalyxin. The concentration of an antigen can therefore be determined by exposing the sample to a near infrared light and quantitatively determining the resulting aggregated mass by measurement of absorbance (turbidimetry) or measurement of a scattered light (nephelometry).

ラテックス粒子にがん細胞特異的抗ポドカリキシン抗体を結合させてサンプルに混合すると、がん特異的ポドカリキシンが存在すれば、抗体結合ラテックス粒子が凝集する。そこで、サンプルに近赤外光を照射して、吸光度の測定(比濁法)又は散乱光の測定(比朧法)により凝集塊を定量し、抗原の濃度を求めることができる。

"(1) an agglutination reaction method in which a moesin or a partial peptide thereof (antigen) is coated on the surface of blood cells or gelatin particles and a biological sample is then added thereto, thereby inducing antigen-antibody reaction to form aggregates;
(2) a double immunodiffusion method (DID: Ouchterlony method) in which an extract containing a moesin or a partial peptide thereof and a biological sample are dispersed in an agar gel to induce precipitation reaction;
(3) methods in which, after immobilizing a purified moesin or a partial peptide thereof onto a plate and then adding thereto a biological sample to allow it to react with the thus immobilized moesin or partial peptide thereof,
i) a secondary antibody bound with an enzyme is further allowed to react and the resulting substrate coloration is detected using a spectrophotometer (ELISA method);
ii) a secondary antibody bound with a fluorescent dye is further allowed to react and the resulting fluorescence is measured (fluoroimmunoassay: FIA); or
iii) a secondary antibody bound with a chemiluminescent substance is further allowed to react and the resulting chemiluminescence is measured (chemiluminescence immunoassay: CLIA); "
