ビリルビンオキシダーゼ(乾燥試薬)と界面活性剤(乾燥試薬)とを用いたビリルビン測定において、測定試料を混合する順番がビリルビンオキシダーゼの反応速度に影響を及ぼすことを確認した。
マイクロプレートのウェル内に、乾燥試薬R1及びR2をそれぞれ調製した。乾燥試薬R1及びR2を測定試料に溶解した場合における各組成の最終濃度は、下記表1のとおりである。
R1
100mM BES pH7.0
5mM EDTA
100U/ml BOD
R2
100mM BES pH7.0
0.5% SDS
50mgの間接型ビリルビン(商品名:ビリルビン、和光純薬社製)を2.5mlのDMSOに溶解し、5mlの0.1M Na2CO3を添加した。この間接型ビリルビン溶液の7.5mlを150mlの正常血清に添加し、さらに、3mlの0.1N HClを添加し、間接型ビリルビン試料を準備した。この試料の濃度を従来公知の液系の定量法で測定したところ、27.3mg/dlであった。
前記測定試料70μlを乾燥試薬R1が調製されたウェルに添加して乾燥試薬R1を溶解し、速やかに、その溶解させた70μlのうち50μlを乾燥試薬R2が調製されたウェルに添加して乾燥試薬R2を溶解した。反応後の吸光度の変化をマイクロプレートリーダーにて、主波長450nm、副波長630nmで測定した(R1→R2測定)。測定は、前記測定試薬を乾燥試薬R1に添加してから120秒後から開始した。R2→R1測定は、乾燥試薬R1とR2とを入れ替えた他は同様にして行った。
R1→R2測定及びR2→R1測定の結果の一例を図3のグラフに示す。同図に示すとおり、R1→R2測定、すなわち、ビリルビンオキシダーゼを先に作用させてその後に界面活性剤を作用させた場合、開始2分後には吸光度のグラフがほぼプラトーに達しているから、ビリルビンとビリルビンオキシダーゼとの反応が速やかに完了したことがわかる(同図左グラフ)。一方、R2→R1測定、すなわち、界面活性剤を先に作用させてその後にビリルビンオキシダーゼを作用させた場合、反応開始8分後でもまだプラトーに達しておらず、ビリルビンとビリルビンオキシダーゼとの反応が未完了であることが分かる(同図右グラフ)。したがって、ビリルビンオキシダーゼ(乾燥試薬)と界面活性剤(乾燥試薬)とを用いたビリルビン測定においては、ビリルビンオキシダーゼを先に測定試料と混合した方が、界面活性剤を先に混合するよりも、測定時間を短くできることが確認された。
実施例1で使用した測定試料(間接型ビリルビン試料:27.3mg/dl)に加えて、濃度が6.0mg/dl、12.1mg/dl及び24.4mg/dlである直接型ビリルビン試料、濃度が8.1mg/dl及び16.1mg/dlである間接型ビリルビン試料、並びに、濃度が0.0mg/dlのビリルビン試料を調製し、実施例1と同様にして、R1→R2測定及びR2→R1測定を行った。前記直接型ビリルビン試料は、ビリルビンとして直接型ビリルビン(商品名:ジタウロビリルビン、Promega社製)を用いたほかは、実施例1の間接型ビリルビン試料の調製方法と同様にして調製した。また、各試料の濃度は、正常血清を用いた希釈により調節した。
乾燥試薬R1におけるBODの最終濃度を10U/ml及び3U/mlとし、乾燥試薬R2における界面活性剤をコール酸ナトリウム(最終濃度0.5wt%及び1.5wt%)とした他は、実施例1と同様にして乾燥試薬R1及びR2を調製し、様々な濃度の直接型/間接型ビリルビン試料を用いてR1→R2の順序で混合してビリルビンを測定した。
乾燥試薬R1におけるBODの最終濃度を1U/mlとし、乾燥試薬R2における界面活性剤をSDSとコール酸ナトリウムとの組み合わせ(最終濃度各0.5wt%及び各1.0wt%)とした他は、実施例1と同様にして乾燥試薬R1及びR2を調製し、様々な濃度の直接型/間接型ビリルビン試料を用いてR1→R2の順序で混合してビリルビンを測定した。
