Abstract
Description
本発明の蛋白質安定化剤は、蛋白質として、ペルオキシターゼ又はアルカリ性ホスファターゼを特に好適に安定化させることができる。
いずれの場合も、蛋白質と蛋白質安定化剤とが共存する蛋白質安定化溶液中における式(1)の化合物の濃度を、0.01~10質量%とすることが好ましく、0.01~0.1質量%とすることがより好ましい。0.01質量%未満であると蛋白質の安定化効果が十分でなく、10質量%を超えると溶液が泡立ちやすく、使用しにくくなる恐れがある。
本発明の蛋白質安定化剤によって蛋白質を安定化させるにあたって、蛋白質安定化溶液を保持する温度は、2℃~40℃が好ましい。2℃以下だと蛋白質安定化溶液が凍結する可能性があり、40℃以上になると安定化できる期間が短くなるからである。

蛋白質安定化剤を用いずに、リン酸緩衝液(pH=7.4)のみを使用した以外は、実施例1-1と同様にして蛋白質安定化効果の評価を行った。結果を表1に示す。
蛋白質安定化剤としてモノラウリン酸ポリオキシエチレンソルビタンを使用し、終濃度が0.5質量%になるよう調製した蛋白質安定化溶液を用いた以外は、実施例1-1と同様にして蛋白質安定化効果の評価を行った。結果を表1に示す。
比較合成例1で得られた化合物を、実施例1-1と同様にして蛋白質安定化溶液の調製を試みたが、比較合成例1で得られた化合物はリン酸緩衝液に溶解しなかったため、蛋白質安定化効果を評価できなかった。
<蛋白質安定化剤溶液の調製>
合成例1で得られた化合物を、トリス緩衝溶液(pH=8.0)に溶解させ、終濃度が表2に示した濃度の2倍の蛋白質安定化剤溶液を調製した。
(1)調製した蛋白質安定化剤溶液と、アルカリ性ホスファターゼ、スクロース及びMgCl2を含むトリス緩衝液(pH8.0)(蛋白質溶液)と、をそれぞれ等量混合し、蛋白質安定化溶液を調製した。該蛋白質溶液中のアルカリ性ホスファターゼ濃度は0.2mg/mL、スクロース濃度は20質量%、及びMgCl2濃度は2mMであった。
従って、蛋白質安定化溶液中には、アルカリ性ホスファターゼは0.1mg/mL含有され、該蛋白質安定化溶液中の合成例1の化合物の濃度は、表2に示した1.000質量%である。
(2)蛋白質安定化溶液を、表2に記載の日数、25℃でインキュベートした。インキュベート後、ポリスチレン製96穴プレートに8μL/wellで加え、1-Step PNPP(Thermofisher Scientific社製)を100μL/well添加し、蛋白質との発色反応を7分間行った。続いて、2Nの水酸化ナトリウムを50μL/well加え、発色反応を停止させた。波長405nmに対する吸光度を測定し、アルカリ性ホスファターゼの安定化効果について評価をおこなった。吸光度は、波長が405nmであることを除いては、上記と同様にして測定した。なお、蛋白質安定化効果は、上記数式(1)から求められる酵素活性残存率(%)により評価した。酵素活性残存率の値が高いほど蛋白質安定化効果が高いことを表す。評価結果を表2に示す。
合成例1の化合物の代わりに合成例2~5の化合物を使用し、表2に示す濃度となるように、実施例2-1と同様にして各蛋白質安定化溶液を調製した。さらに、実施例2-1と同様にして各実施例の蛋白質安定化効果を評価した。結果を表2に示す。
蛋白質安定化剤溶液の代わりに、トリス緩衝液(pH=8.0)のみを使用し、かつ蛋白質溶液中にスクロースを添加しない以外は、実施例2-1と同様にして蛋白質安定化効果の評価を行った。結果を表2に示す。
蛋白質安定化剤溶液の代わりに、トリス緩衝液(pH=8.0)のみを使用した以外は、実施例2-1と同様にして蛋白質安定化効果の評価を行った。結果を表2に示す。
