(2)測定対象物質が検体中で遊離体と結合体で存在するものであり、測定対象物質に対するモノクローナル抗体1が固定化されたラテックス1、及び抗体1とは測定対象物質に対する認識部位が異なるモノクローナル抗体2が固定化された、ラテックス1とは平均粒径の異なるラテックス2と、測定対象物質とを反応させ、生じる凝集反応の結果に基づいて測定物質量を求めることを特徴とする、免疫学的測定方法、
並びに
(3)測定対象物質が検体中で遊離体と結合体で存在するものであり、測定対象物質に対するモノクローナル抗体1が固定化されたラテックス1と、抗体1とは測定対象物質に対する認識部位が異なるモノクローナル抗体2が固定化された、ラテックス1とは平均粒径の異なるラテックス2とを含む、免疫学的測定用試薬と、抗原抗体反応の凝集促進剤を含んでなる試薬とからなる免疫学的測定法用試薬キット、に関する。
で表されるモノマーに由来するモノマー単位を有するもの等が挙げられる。
(1)抗ヒトPSA抗体感作(固定化)ラテックス試液の調製
抗ヒトPSAマウスモノクローナル抗体(クローンNo.PSA10)(和光純薬工業(株)社製)0.3mgを含む50mMホウ酸緩衝液(pH7.1)0.5mlと、ポリスチレンラテックス〔平均粒径0.22μm若しくは0.28μm、積水化学工業(株)社製〕を2%(W/V)となるように懸濁させた50mMホウ酸緩衝液(pH7.1)0.5mlとを混合し、25℃で2時間反応させた。その後、遠心分離により分離したラテックスを50mMホウ酸緩衝液(pH7.1)で洗浄し、該ラテックスを濃度が1%(W/V)となるように、BSAを0.5%(W/V)含有する50mMホウ酸緩衝液(pH7.3)中で懸濁し、得られたものを抗ヒトPSA抗体感作ラテックス試液[1]とした。
フリーPSA標準品、コンプレックスPSA標準品(スタンフォード大学製)を1%BSAを含有する10mM リン酸緩衝液(0.85%NaCl含)で希釈し、25ng/mlとした。試薬盲検には上記リン酸緩衝液を使用した。
I.第1試液
0.1%BSA及び1%NaClを含む100mM HEPES−NaOH緩衝液(pH7.0)を第1試液とした。
II.第2試液
(1)で調製した抗ヒトPSA抗体感作ラテックス試液[1]及び[2]をそれぞれ0.1%(W/V)ラテックスに調整し、等量混合したものを第2試液とした。
PSA濃度の測定は自動分析装置(日本電子(株)BM−8形)を用い、以下の測定条件で測定を行った。
試 料 : 5μl
第1試液: 90μl
第2試液: 30μl
測定方法:2ポイントエンド法(34−65)
主波長 :571nm
得られた吸光度(濁度)を表1に示した。尚、表中の値は、得られた吸光度を10000倍にしたもので、ブランク値を減算した値である。また、偏り度γは、フリーPSAの傾き(実測値/理論値)をコンプレックスPSAの傾き(実測値/理論値)で割った値であり、この値が1.0に近いほど、抗体感作ラテックスがフリー体及びコンプレックス体と等モルで結合していることを表す。
2種の抗ヒトPSAマウスモノクローナル抗体(クローンNo.PSA10及びPSA14)(和光純薬工業(株)社製)をそれぞれ0.6mg含む50mMホウ酸緩衝液(pH7.1)0.5mlと、ポリスチレンラテックス〔平均粒径0.22μm、積水化学工業(株)社製〕を2%(W/V)となるように懸濁させた50mMホウ酸緩衝液(pH7.1)0.5mlとを混合し、25℃で2時間反応させた以外は、実施例1と同様の方法でラテックスを調製し、実施例1と同様の測定を行った。得られた結果及び偏り度γを、実施例1と併せて表1に示した。
フリーPSA標準品、コンプレックスPSA標準品(スタンフォード大学製)を1%BSAを含有する10mM リン酸緩衝液(0.85%NaCl)で希釈し、0、5、10、25、50ng/mlとした。
I.第1試薬
実施例1で調製した第1試薬を用いた。
II.第2試薬
実施例1で調製した抗体感作ラテックスのうち、抗体感作ラテックス[1]は平均粒径0.28μmラテックスに感作したものを用い、抗体感作ラテックス[2]は平均粒径0.15μmラテックスに感作したものを用い、実施例1と同様にして混合した。
PSA濃度の測定は自動分析装置(東芝TBA-120FR形)を用い、以下の測定条件で測定を行った。
試 料 : 12μl
第1試液: 120μl
第2試液: 40μl
測定方法:2ポイントエンド法(20−33)
主波長 :572nm
得られた吸光度(濁度)及び偏り度γを表2に示した。尚、表中の吸光度値は、得られた吸光度を10000倍にしたもので、ブランク値を減算した値である。表中の測定値はフリーPSA標準品から作製した検量線を用いて算出した値である。また、得られたフリー体のPSAとコンプレックス体のPSAの吸光度と、各濃度との関係(グラフ)を図1に示した。
比較例1で調製した2種の抗体感作ラテックス(平均粒径0.22μm)を用いた以外は、実施例2と同様の測定を行った。得られた結果及び偏り度γを、実施例2と併せて表2に示した。
