Abstract
Description
a)HPV遺伝子産物の検出のための試薬
b)p16INK4a過剰発現の検出のための試薬
c)検出反応を成し遂げるために通常使用される試薬および緩衝液(例えば、緩衝液、検出マーカー、キャリア物質など)
d)ポジティブコントロール反応を成し遂げるためのp16INK4aサンプル
e)ポジティブコントロール反応を成し遂げるためのHPV遺伝子産物
HPV遺伝子産物および/またはp16INK4aの検出のための試薬は、HPV遺伝子産物および/またはp16INK4a分子に結合し得る任意の薬剤を含み得る。このような試薬としては、タンパク質、ポリペプチド、核酸、ペプチド核酸、糖タンパク質、プロテオグリカン、多糖類または脂質が挙げられる。
子宮頚部のスミアを、p16INK4aに特異的な抗体およびHPV E2タンパク質に特異的なポリクローナル抗体を使用して、免疫細胞学的に染色した。
子宮頚部のスミアを、p16INK4aおよびHPV E2およびL2のmRNAレベルについて、インサイチュ染色反応で、半定量的に分析し得る。この染色反応を、以下のように実行する:
再水和のために、スプレー固定したスミアを、振動デバイス上にある新鮮な50%EtOH中でインキュベートする。この固定手順により産生したPEGフィルムを、激しい洗浄により除去する。次に、このスミアを水中ですすぐ。このスミアを、プロテイナーゼK(PBS中に10μg/ml)とともに10分間37℃で培養する。次いで、このスライドを、洗浄緩衝液(PBS/0.1% Tween20)に移し、そして最終的に脂質ペンで囲む。
子宮頚部のスミアのThinPrep(登録商標)薄層を、p16INK4aに特異的な抗体およびHPV E7タンパク質に特異的モノクローナル抗体を使用して、免疫細胞学的に染色する。
従って、このスライドを、水浴中で40分間95〜98℃で温め、20分間室温に冷まし、洗浄緩衝液(Dakocytomation、S3006)に移し、そして最終的に脂質ペンで囲む。
