Description
配列表は、EFS−Webを介して作成日が2016年6月16日でサイズが3.14キロバイトであるSequenceListing.txtというファイル名の、ASCIIフォーマット済テキストファイルとして明細書と共に同時に提出されている。EFS−Webを介してファイルされた配列表は、本明細書の一部であり、そして参照によりその全体が本明細書に援用される。
「アンプリコン(アンプリコン)」とは、天然又は人工の増幅又は複製源及び/又は複製産物である、DNA又はRNAの一片である。これに関して、「増幅(amplification)」とは、遺伝子断片又は標的配列、特に1コピー又は2コピー以上のアンプリコンの生成を意味する。増幅反応産物として、アンプリコンは、一般的な実験用語、例えばPCR産物と互換的に使用される。
遺伝子特異的PCRのPCR反応混合物25μLには、典型的に以下のものが含まれる:2μLのヒトゲノムDNA(PromegaCat#G3041(低TE緩衝液(USBCat#75793))を用いて5ng/μLに希釈)、12.5μLの2×MasterMix(QiagenCat#206413)、8.5μLヌクレアーゼフリー水、及び2μLの遺伝子特異的プライマーミックス(各2.5μM、表3のミックス情報および表1のオリゴヌクレオチド配列を参照のこと)。
1サイクル 95℃ 15分 酵素活性化と初回DNA変性
30サイクル 95℃ 30秒 変性
60℃ 90秒 アニーリング/伸長
1サイクル 72℃ 5分 最終的な伸長
1サイクル 8℃ 保持
PCR反応ミックスは実施例1で使用したものと同じだが、二段階PCRはサーマルサイクラ−のサイクルプロトコルが異なる。最初の5サイクルのアニーリングと伸長は、実施例1と同じ60℃で実施した。これに続く25サイクルのアニーリングと伸長は、プライマーダイマー形成の開始を阻害するために温度を上げて68℃で実施した。
1サイクル 95℃ 15分 酵素活性化と初回DNA変性
5サイクル 95℃ 30秒 変性
60℃ 90秒 アニーリング/伸長
25サイクル 95℃ 30秒 変性
68℃ 90秒 上昇させた温度にてアニーリング/伸長
1サイクル 72℃ 5分 最終的な伸長
1サイクル 8℃ 保持
PCR産物をE−Baseデバイス(LifeTechnologies)で分析した。2μLの各PCR産物を18μLのヌクレアーゼフリー水と混合し、2%Eゲルに直接載せた。希釈PCR産物と50bpDNAラダー(Invitrogen Cat#10488〜043)のDNA電気泳動を行った。泳動の最後にゲルのデジタル画像をE−gelImager(LifeTechnologies)で撮影した。結果を図3に示す。
