移動相:50mM リン酸二水素ナトリウム
検出器:示差屈折率計
また、培養して得られた菌体のホスファターゼ活性は、p−ニトロフェニルリン酸エステルからp−ニトロフェノール(ε=16600M−1cm−1、pH6.0)への変化を410nmの吸光度の増加を測定することにより求めた。ホスファターゼ活性の測定条件は次のとおりである。
[参考例1]
公知のShigella flexneri 2a YSH6000に由来する酸性ホスファターゼ配列をもとに、配列番号1および配列番号2に示した2種のプライマーを作成し、Shigella flexneri 2a YSH6000由来の酸性ホスファターゼをコードする遺伝子を含むプラスミドを鋳型としてPCRを行った。10mMのKOD−plusバッファー、1.5μMのフォワードおよびリバースプライマー、1mMの硫酸マグネシウム、0.2mMのdNTPs、2UのKOD−plusポリメラーゼ(TOYOBO)、50ng/μLの鋳型DNAからなる反応溶液を作成した。94℃で2分間保持した後、94℃で30秒間、60℃で30秒間、68℃で1分間のサーマルサイクルを30サイクル行った後、最後に68℃で10分間保持した。その結果、約0.75kbの増幅断片が得られた。得られた断片をPstI/BamHI処理し、pUC19に連結した。作成したプラスミドを用いて大腸菌DH5α株を形質転換して、ホスファターゼ活性の発現株を作成した。
