Abstract
【解決手段】 円筒状の第一部材11と、第一部材11の中空部に収容された円柱状の第二部材12と、第二部材12の外周面に固定されたプローブとを備えたプローブアレイ1において、第一部材11の内周面と第二部材12の外周面との接触を防止するスペーサー部13aを第二部材12の外周面に設ける。

Description
図1(a)は一実施形態に係るプローブアレイの斜視図、図1(b)は同プローブアレイの断面図である。
(1)突起部を有するプラスチックフィルムの作製
ポリエステル(80メッシュ)のスクリーンに直径1mmの円形パターンを複数形成し、スクリーン版を作製した。この際、円形パターン間の距離は中心間の距離が4mmとなるように調整した。上記スクリーン版及びUV硬化型スクリーン印刷用インキ(東洋インキ製造(株)製,SS点字用インキ)を用いてスクリーン印刷し、縦19mm×横12mmのポリエステルフィルム(東レ(株)製,ルミラー,厚さ50μm)上に複数の突起部を形成させた。この際、硬化はメタルハライドランプ1灯、120W/cm、10m/分の条件で行った。
こうして、図3に示すように、複数の突起部(高さ:500μm)を有するプラスチックフィルムを作製した。
上記(1)で作製した突起部を有するプラスチックフィルムをポリL−リジン溶液(濃度:0.01%、溶媒:0.1×PBS)に浸して、1時間振盪した。次いで、超純水中で4回激しく洗浄し、余分なポリL−リジンを洗い流した。次いで、バキュムオーブンにより60℃で4時間乾燥させ、ポリL−リジンをプラスチックフィルムに密着させた。
上記(2)で作製したプローブDNA固定化プラスチックフィルムを、プローブDNA固定化面が外周面を構成するように、直径2.8mm×長さ3cmのガラス棒に巻き付けた後、内径4mm×長さ3cm×厚み100μmのポリエチレンテレフタレート製透明プラスチック筒に挿入した。このとき、プラスチックフィルム上に形成された突起部が、プローブDNA固定化面とプラスチック筒の内周面との接触を防止するスペーサー部としての役割を果たす。
上記(3)で作製したキャピラリー型プローブアレイの中空部に、標的オリゴヌクレオチドを含むハイブリダイゼーション溶液(標的オリゴヌクレオチド濃度:1pmol/μL、イーストtRNA濃度:1μg/μL、溶媒:0.2%SDS含有3×SSC)100μLを吸い上げ、キャピラリー型プローブアレイの両端をパラフィルムで閉じて40℃の恒温槽内で一晩加温した。なお、標的オリゴヌクレオチドとしては5’末端にビオチンを結合させた22merのポリ(dT)を使用した。
恒温槽からキャピラリー型プローブアレイを取り出し、ハイブリダイゼーション溶液を排出した後、非特異的に吸着した標的オリゴヌクレオチドを洗い流すために、キャピラリー型プローブアレイの中空部を洗浄バッファー1(2×SSC、0.1%SDS)で満たして10秒間放置した。洗浄バッファー1を排出した後、洗浄バッファー2(1×SSC)を満たして10秒間放置し排出する操作を3回繰り返した。次いで、洗浄バッファー3(0.2×SSC)についても洗浄バッファー2と同様の操作を行った。
キャピラリー型プローブアレイの中空部をブロッキング溶液(1%カゼイン、3×SSC)で満たし、室温で30分間ブロッキングを行った。ブロッキング溶液を排出した後、ストレプトアビジン/アルカリフォスファターゼ複合体溶液(原液を0.2M NaCl、0.1M Tris−HCl(pH7.4)、0.05% Triton−X、1% カゼイン溶液で2000倍に希釈したもの)を満たし、室温で30分間反応させた。ストレプトアビジン/アルカリフォスファターゼ複合体溶液を排出した後、緩衝液A(0.2M NaCl、0.1M Tris−HCl(pH7.4)、0.05% Triton−X)を満たし、5分間放置した後、排出した。これを2回繰り返し、標的オリゴヌクレオチドに結合しているビオチンに結合しなかったストレプトアビジン/アルカリフォスファターゼ複合体を除去した。次いで、緩衝液B(0.2M NaCl、0.1M Tris−HCl(pH7.4))を満たして10秒間放置した後、排出した。最後に基質溶液(緩衝液B 10mL、BCIP(5−ブロモ−4−クロロ−3−インドリルフォスフェート)溶液9μL、NBT(ニトロブルーテトラゾリウム)溶液18μL)を満たし、室温で3時間放置し、発色反応を行った。
