Description
項1. 毛髪中に蓄積された生理活性物質の解析方法であって、以下の工程
工程1:毛髪を長軸方向にスライスし、髄質を露出させる工程
工程2:工程1で露出した表面に内部標準物質を適用する工程
工程3:工程2で得られた表面についてイメージング質量分析(IMS)を行い、毛髪中の生理活性物質を連続的かつ定量的に検出する工程
を含むことを特徴とする、毛髪中に蓄積された生理活性物質の解析方法。
項2. 前記生理活性物質が違法薬物である、項1に記載の解析方法。
項3. IMSがMALDI−TOFMSを用いて行われる、項1又は2に記載の解析方法。
項4. 工程1の毛髪のスライスをミクロトームにより行う、項1〜3のいずれかに記載の解析方法。
項5. 工程1の毛髪のスライスを凍結及び固定された毛髪に対して行う、項1〜4のいずれかに記載の解析方法。
項6. IMSが走査型IMSである項1〜5のいずれかに記載の解析方法。
実施例1
(1)毛髪表面の洗浄
毛髪(2cm程度)を栓付き試験管に入れ、
1)0.5%SDS溶液中で1分間超音波洗浄後、SDS溶液を吸引
2)精製水中で1分間超音波洗浄後、精製水を吸引
3)メタノールで1分間超音波洗浄後、メタノールを吸引
4)2)→3)を2回繰り返す
5)洗浄毛髪を試験管より取り出し、キムワイプ上で乾燥
1) スポンジ研磨材による剥離法(従来法)
*洗浄毛髪の両端を固定し、スポンジ研磨材(住友スリーエム(株):超極細目#1500)で実体顕微鏡下、観察しながら表面キューティクルを擦り取る(25回程度)。
*髄が顕微鏡下で確認出来た時点で終了し、湿らせた脱脂綿等で表面のゴミを軽く拭き取る。
*ITOスライドガラス(Bruker Daltonics社:237001)に導電性両面テープ(日東電工(株):No.5601)を張り付け、その上に擦り面が上になる様に毛髪をしっかり固定し、IMS解析に供する。
2) ミクロトームによる超薄切法(本発明法)
*洗浄毛髪を導電性両面テープ(日東電工(株):No.5601)に張り付け、ガラススライドに固定し、生物試料凍結ユニット((株)日本ミクロトーム研究所)を用いて毛髪を氷結(-20℃)させる。
*生物試料凍結ユニットを実体顕微鏡付き手動式ミクロトームシステム((株)日本ミクロトーム研究所)取り付け-20℃下、ガラスナイフにて2μm毎凍結毛髪を削いで行く。
*実体顕微鏡で観察しながら髄が出現した時点で、終了する。平均ヒト毛髪直径を100μmと仮定すると、25サイクル(2μm×25=50μm)すればよい。
*終了後、生物試料凍結ユニットを室温に戻し、導電性両面テープ上の水滴を軽く拭き取った後、ユニットからガラススライドを取り外す。
*ガラススライド上の導電性両面テープを慎重に剥がし、ITOスライドガラスに移し、IMS解析に供する。
1) MALDI-TOFMS機器
使用機器:Autoflex speed(Bruker Daltonics社製smart beamII)
SRM定量解析:モニターイオンはParent ion:163.2>Fragment ion:132.2
NCはm/z=132.2、13C3-NCはm/z=135.2をモニターし、132.2/135.2のピーク高さ比より定量する。
2) マトリックス
αシアノ-4-ヒドロキシ安息香酸(CHCA: SIGMA社製c2020、Lot No:MKBH1245V)を0.2%トリフルオロ酢酸/50%アセトニトリル溶媒にて7mg/mLに調整し、ImagePrepTM(Bruker Daltonics社製)にて毛髪断面に噴霧する。
3) 内部標準物質
13C3-NC(CIL社:CLM-3914-0.1)のメタノール溶液を希釈し、上記CHCA溶液に終濃度50ng/mL添加し、マトリックスと共に毛髪断面上に噴霧する。
4) ImagePrep操作
Bruker Daltonics社指定のファイル「HCCA_nsh05」にて噴霧操作を実施。
5) 定量計算
毛髪1cm長(=0.04mm3)のピーク高さ比から「pg/mg Hair」値を算出
計算式=(132/135)x 25 x 50
1)本法でのNC値の再現性 (長期喫煙者毛髪:>30本/日、>20年間)
9.5 +/- 1.2 ng/mg Hair
34.5 +/- 2.8 ng/mg Hair CV =10%前後
2)従来法との比較: NC溶液(0.1、1.0 μg/mL)を添加した非喫煙者毛髪
本法:0.22、0.36 ng/mg (従来法:0.21 ng/mg)
0.60、1.13 ng/mg (従来法:0.97 ng/mg)
3)3処理法(未処理、スポンジ研磨材による剥離法、ミクロトームによる超薄切法)での比較(図3) 試料毛髪:NC 1.0μg/mL添加毛髪

結果を表1及び図1〜3に示す。
今回、標識安定同位体を内部標準に用い、毛髪断面走査定量イメージング解析法を新規開発し、喫煙者毛髪中ニコチン(NC)定量に応用した。本法は、毛髪表面のキューティクル層をガラスナイフ付きミクロトームにて剥ぎ落とし、NC特有のMSイオン(m/z=163/132)を指標に毛髪断面(超薄切)上を連続走査することで時間毎/数ヶ月間NC値の連続追跡が出来き、更に標識安定同位体(13C3-NC:m/z=166/135)を内部標準とし、高精度・高感度定量測定が可能となった。
