Description
本発明における第一の反応層8は、酸化還元酵素を含む。酸化還元酵素としては、好ましくは、補欠分子族(「補酵素」とも称する)としてピロロキノリンキノン(PQQ)、フラビンアデニンジヌクレオチド(FAD)、またはフラビンモノヌクレオチド(FMN)を含む。特に、補欠分子族としてピロロキノリンキノン(PQQ)を含むポリオール脱水素酵素が好ましい。なお、本発明においては、本発明の酸化還元酵素を単独で、または混合物の形態として使用してもよい。
また、本発明における第二の反応層9は、脂質を構成するエステル結合を加水分解する脂質分解酵素を含む。ゆえに、本発明のバイオセンサは、中性脂肪センサとして使用することができる。かような脂質分解酵素として、特に制限されないが、具体的には、リポプロテインリパーゼ(LPL)、リパーゼ、エステラーゼが好適に挙げられる。特に、反応性の観点で、リポプロテインリパーゼ(LPL)が好ましい。
本発明に係るバイオセンサは、電子伝達体を含むことが好ましい。ここで、電子伝達体は、第一の反応層8または第二の反応層9に含まれてもよい。好ましくは、第二の反応層9に含まれる。なお、電子伝達体は、界面活性剤層12に含まれていてもよい。
本発明に係る好ましい実施形態のバイオセンサにおいて、第一の反応層8、第二の反応層9および界面活性剤層12の少なくとも一層は、界面活性剤を有する。好ましい形態においては、電極表面へのタンパク質の固着を防止するとの観点から、第一の反応層8に、界面活性剤を有する。また、好ましい形態においては、本発明のバイオセンサにおいては、第一の反応層8および第二の反応層9と離間されて、界面活性剤が含まれる界面活性剤層12がカバー7側に形成される。カバー7側に界面活性剤層が形成されていると、カバー7が直接試料に触れる場合よりも、カバー側への全血等の試料の広がりや濡れ性がよくなり、試料を試料供給部に素早く導入できるため好ましい。
本発明に係る好ましい実施形態のバイオセンサにおいて、第一の反応層8、第二の反応層9および界面活性剤層12の少なくとも一層は、親水性高分子を有する。この際、電極表面上に均一に固定化するとの観点から、第一の反応層8に含ませることが好ましい。
本発明のバイオセンサにおいて、第一の反応層8および第二の反応層9は、少なくともトレハロースを含む。本明細書において、第一の反応層8に含まれるトレハロースを、第一のトレハロースと称し、第二の反応層9に含まれるトレハロースを、第二のトレハロースと称する。
本発明に係る好ましい実施形態のバイオセンサにおいて、第一の反応層8、第二の反応層9および界面活性剤層12の少なくとも一層は、血液抗凝固剤を有する。ただし、センサ試料供給部への血液導入をより均一にする観点から、好ましい形態によれば、前記第一の反応層、前記第二の反応層および前記界面活性剤層が、いずれも、血液抗凝固剤を含む。
本発明に係る好ましい実施形態のバイオセンサにおいて、第一の反応層8、第二の反応層9および界面活性剤層12の少なくとも一層は、ホウ酸またはその誘導体を有する(ただし、かかる「ホウ酸またはその誘導体」の概念からは、後述する「トリスホウ酸」は除く)。これにより、測定値に対する血液中のグルコースの影響をほとんど無くすかまたはまったく無くすことができ、どのような血糖値であっても、所定の測定値が得られ、測定値のばらつきがほとんど生じない。
本発明に係る好ましい実施形態のバイオセンサにおいて、第一の反応層8、第二の反応層9および界面活性剤層12の少なくとも一層は、トリスホウ酸を含む。
(使い捨て型バイオセンサの作製)
使用する電極基板には、独自に設計・製造した3電極系の電極基板を使用した。この電極基板は、絶縁性基板1の上に、それぞれカーボンからなる作用極2、参照極3、対極4が形成され、絶縁層5を挟んで、カーボンからなる作用極作用部分2−1、銀/塩化銀からなる参照極作用部分3−1、カーボンからなる対極作用部分4−1が形成されている(図3)。
第一の反応層8(GLDH層)は以下の手順で形成した。
PQQ依存性グリセロール脱水素酵素を0.375U;
エマルゲンPP−290(花王株式会社)を0.05質量%(0.25μg);
トリスホウ酸(トリス(ヒドロキシメチル)アミノメタンおよびホウ酸水溶液を等モル濃度で混合し、pH7.5に調整)を10mM(0.37μg);
トレハロース二水和物(和光純薬工業株式会社製)を6.0質量%(30μg);
ポリビニルアルコール500(和光純薬工業株式会社製)を0.5質量%(2.5μg);
ヘパリンナトリウム(和光純薬工業株式会社製)を0.1U;
になるように混合し、溶液を得た。得られたGLDH溶液を滴下し、40℃で5分間乾燥させ、第一の反応層(GLDH層)を得た。
第二の反応層9(LPL層)は以下の手順で形成した。
リポプロテインリパーゼ(LPL、旭化成株式会社製)を90U;
ヘキサアンミンルテニウム(III)塩化物(和光純薬工業株式会社製)を200mM(62μg);
トリスホウ酸を10mM(0.37μg);
トレハロース二水和物(和光純薬工業株式会社製)を3.0質量%(15.0μg);
四ホウ酸カリウム(和光純薬工業株式会社製)を80mM(12μg);
ヘパリンナトリウム(和光純薬工業株式会社製)を0.1U;
になるように混合し、溶液を得た。得られたLPL溶液を、形成させたGLDH層の上に重層(被覆)するように滴下し、50℃で5分間乾燥させ、第二の反応層9(LPL層)を得た。このようにして、第一の反応層8であるGLDH層、さらにその上に第二の反応層9であるLPL層を形成(重層)した。
界面活性剤層12は以下の手順で形成した。
エマルゲンPP−290(花王株式会社製)を0.1質量%(0.5μg);
ヘパリンナトリウム(和光純薬工業株式会社)を0.08U;
になるように混合し、界面活性剤溶液を得た。得られた界面活性剤溶液を、PETからなるカバーに接着剤を貼り合わした隙間に滴下後、50℃で5分間乾燥させ、界面活性剤層を形成した。
界面活性剤層が形成されているカバーに接着した接着剤(両面テープ)と、第一の反応層と第二の反応層とが形成されている電極基板とを互いに貼り合わせることにより、使い捨て型バイオセンサを作成した。
バイオセンサを50℃で0〜42日間保存後にGLDH活性を測定し、バイオセンサ作製直後に測定したGLDH活性を100とした場合の残存活性として算出した。なお、図5では、0,7,14,21,28,35,42日後の残存活性をプロットしている。
試料液(ヒト全血)0.5μlを吸入させてから45秒後に、参照極を基準にして作用極と対極の間に+200mVの電位を印加し、1秒後に作用極と対極との間に流れる電流値を測定した。なお、電流値は、作製した直後のバイオセンサを使用して、測定している。
第二のトレハロースの含有量に対する前記第一のトレハロースの含有量の比を3(第一のトレハロース含有量:45.0μg、第二のトレハロース含有量:15.0μg)にした以外は実施例1と同様にしてバイオセンサを作製した。50℃保存安定性におけるGLDH残存活性の結果を表1および図4に示す。また電流値の測定結果について表2および図5に示す。
第二のトレハロースの含有量に対する前記第一のトレハロースの含有量の比を10(第一のトレハロース含有量:150.0μg、第二のトレハロース含有量:15.0μg)にした以外は実施例1と同様にしてバイオセンサを作製した。50℃保存安定性におけるGLDH残存活性の結果を表1および図4に示す。また電流値の測定結果について表2および図5に示す。
第二のトレハロースの含有量に対する前記第一のトレハロースの含有量の比を15(第一のトレハロース含有量:225.0μg、第二のトレハロース含有量:15.0μg)にした以外は実施例1と同様にしてバイオセンサを作製した。50℃保存安定性におけるGLDH残存活性の結果を表1および図4に示す。また電流値の測定結果について表2および図5に示す。
第二のトレハロースの含有量に対する前記第一のトレハロースの含有量の比を1:1(第一のトレハロース含有量:15.0μg、第二のトレハロース含有量:15.0μg)にした以外は実施例1と同様にしてバイオセンサを作製した。50℃保存安定性におけるGLDH残存活性の結果を表1および図4に示す。また電流値の測定結果について表2および図5に示す。
図4の結果より、実施例1では比較例1と比較して約2倍保存安定性が向上しており、実施例2では比較例1と比較して約5倍保存安定性が向上することがわかった。また実施例3および実施例4においても保存安定性の効果が維持されていることがわかった。
