MALDI−MSによる組織切片におけるmRNAの間接検出のための光開裂可能なリンカーを有するオリゴペプチド接合体の使用
光開裂可能なリンカーを有するオリゴペプチド接合体について、MALDI−MSによる組織切片における特異的mRNAを間接検出することができる能力を試験した。
オリゴペプチド接合体は、下記のプロトコルを用いて合成した。
幾つかの一般に用いられるマトリックスを、区別せずMALDI−MS分析に用いた: α−シアノ−4−ヒドロキシ桂皮酸 (CHCA)、3−ヒドロキシピコリン酸 (HPA)およびシナピン酸 (SA)。
MALDI−TOF質量スペクトルは、遅延引き出し(DE)を有し、かつ337nmのパルスド窒素レーザーで操作するVoyager−DE STR質量分析計(Applied Biosystems, フラミンガム, マサチューセッツ, 米国)で行った。
イノックス(inox)MALDIプレートについては、取得パラメーターを下記のように設定した: 加速電圧:20kV;第1のグリッド電圧:94%;ガイドワイヤー電圧:0.05%;引出遅延時間:100−250ナノ秒。
加速電圧:20kV,第1のグリッド電圧:70%,ガイドワイヤー電圧:0.05%,引出遅延時間:200ナノ秒。
イメージ再構築(image reconstruction)には、ソフトウェア flexImaging (Bruker daltonics,ブレーメン,ドイツ国)を用いた。
プロエンケファリンのPCR増幅は、タグ付き(ペプチド−光開裂可能なリンカー−オリゴヌクレオチド)または通常の(光開裂可能なリンカーおよびペプチド残基のない)フォワード(5’−CAG−GAC−TCC−CCA−AAG−GAG−AAC−AGG−A−3’,配列番号:9,表2参照)およびリバーズ(5’−GA−CGT−ACC−AGG−CGG−TAG−CTG−CAT−TT−3’,配列番号:10,表2参照)プライマーを用いて得た。
上記で合成した修飾ペプチドタグ付きdUTPを組込んでいるプロエンケファリン核酸プローブ(400bp)(1.1.6項参照)を、1.1.5項に記載の通常のフォワードおよびリバースプライマーを用いるRT−PCRによって合成した。
1.2.1 様々な分析モードでの1個または多数のオリゴペプチド接合体の検出
3種類のオリゴペプチド接合体を、様々な分析モードで別々にまたは同時に分析した(図4)。
表面でのオリゴペプチド接合体のマッピングの可能性を評価するため、オリゴペプチド3からなるX文字のイメージをMALDIプレート上にマルチピペットを用いて描いた。
オリゴペプチド接合体をフォワードおよび/またはリバースプライマーとして用いて一層大きなハイブリダイゼーションプローブを合成することが可能であることを確かめるために、タグ付き(ペプチド−光開裂可能なリンカー−オリゴヌクレオチド)または通常の(光開裂可能なリンカーおよびペプチド残基のない)フォワード(5’−CAG−GAC−TCC−CCA−AAG−GAG−AAC−AGG−A−3’)およびリバース(5’−GA−CGT−ACC−AGG−CGG−TAG−CTG−CAT−TT−3’)プライマーを用いてPCR増幅を行った。
in situハイブリダイゼーションは、上記のようにパラフィンを除去したラット脳切片上でペプチドタグ付きハイブリダイゼーションプローブを用いて行った。
材料および方法の節に記載の合成プロトコルを用いて、図8Aに示した式を有する修飾ペプチドタグ付きdUTPヌクレオチドを合成した。
これらの結果は、ペプチドタグ付きプライマーで合成したハイブリダイゼーションプローブを用いて、核酸−光開裂可能なリンカー−ペプチド接合体を使用することにより組織切片中の多数のmRNAターゲット分子の間接的同時検出が可能であることを明確に示している。
MALDI−MSによる組織切片におけるタンパク質の間接検出のための光開裂可能なリンカーを有する抗体−ペプチド接合体の使用
光開裂可能なリンカーを有する抗体−ペプチド接合体を合成し、MALDI−MSを用いる組織切片における特異的なタンパク質を間接検出するその能力について試験した。
ウサギ抗体の枠組構造領域に特異的なヤギ抗体(ヤギ抗ウサギ抗体)を用いて、UV−MALDIレーザー波長で光開裂可能なリンカーを有する抗体−ペプチド接合体を合成した。この方法では、この接合体は、一次ウサギ抗体が利用可能な任意のペプチド、タンパク質、抗原またはハプテンの間接分析に対する二次抗体として適している。更に、下記の合成プロトコルは任意のペプチド、タンパク質、抗原、またはハプテンなどの任意の特異性を有する任意の抗体に応用可能であるので、抗体が別の種類の抗体または任意の所望なペプチド、タンパク質、抗原もしくはハプテンに特異的である他の接合体を下記のプロトコルを用いて容易に合成することができる点に留意しなければならない。
1. 光開裂可能なリンカーを用いる固相ペプチド合成(古典的Fmoc法)
2. 水/アセトニトリル+0.5% TFAを用いるRP−HPLC(C18)によるペプチドの精製
3. MBS 0.5mgをDMF 300μlに溶解
4. IgG(ヤギ抗ウサギ)4mgをPBS 2mlに溶解
5. 生成物3および4をゆっくり混合。反応は、20℃で30分間攪拌下で起こる
6. PD10を用いて50mMリン酸緩衝液 pH 6により塩を除去
7. ペプチド1mgをDMF 300μlに溶解した後、PBS 1mlを加えた。
8. このペプチド溶液を活性抗体溶液に添加すると、反応が暗所にて20℃にて3時間攪拌下で起こる
9. PBSを一晩透析によって除去。
次に、光開裂可能なリンカーを用いて得られた抗体−ペプチド接合体を、最初に溶液中で試験して、タグペプチドのUV−MALDIレーザーによって誘発される光解離によって効率的に開裂される能力を確かめた。
光開裂可能なリンカーを用いて得られた抗体−ペプチド接合体を、次にラット脳組織切片における膜タンパク質カルボキシペプチダーゼD (180 kDa)の間接UV−MALDI分析について試験した。
組織切片に存在する生体分子の間接質量分析法による分析に、光解離の代わりに迅速断片化を用いることができることの証明
迅速断片化は、通常は有害であるが避け難い現象と考えられている。
このコンセプトはSIMSまたはDESI質量分析法のような他の質量分析法の技術に置き換えることができるが、本発明者らは、MALDI質量分析法と、リンカーがUV−MALDIレーザーの波長で光開裂可能な接合体を用いるこのコンセプトの使用が可能であることを最初に明らかにした。
予想された光解離断片=(ペプチド2+PC),m/z=1892;および
迅速断片化による断片=ペプチド2のみ,m/z=1450。
予想された光解離断片=(ペプチド3+PC),m/z=1604;および
迅速断片化による断片=ペプチド3のみ,m/z=1162。
予想された光解離断片=(ペプチド+PC),m/z=1702;および
迅速断片化による断片=ペプチド+PC+システイン,m/z=1822。
本発明者らは、通常の、特に市販の標識抗体を用いる組織切片に存在する生体分子の間接質量分析法による分析のために迅速断片化を用いる可能性についても分析した。
得られた結果は、様々な質量分析法の技術、特にMALDI、SIMSまたはDESI質量分析法を用いる、組織切片におけるターゲット分子の間接検出に、通常は有害な迅速断片化の現象を利用することができることを明らかに示している。
