Abstract
【解決手段】合成樹脂製で作成された基板1の表面であって、堰リブ2で周囲を取り囲まれた薬液注入領域3内に被検体Sの保持領域4を設け、該保持領域に複数の独立した突起5を繰返しパターンで一体形成し、接近した複数の突起が連係して被検体を1個のみ保持できる単位保持部Hを形成するとともに、各突起の間を薬液の流路6とし、堰リブの高さを突起の高さ以上に設定してなる。
【選択図】 図1
Description
次いで抗原溶液を薬液注入領域3に流し入れ緩衝液と交換し、抗原による刺激を受けた細胞の蛍光を測定する。刺激後1〜2分後の蛍光強度(B)を測定する。刺激前後の蛍光強度比(B/A)の高いウェルの細胞を選別する。抗原刺激により反応した細胞を、未刺激の細胞の蛍光強度と抗原による刺激を受けた細胞の蛍光強度の比(B/A)により選別し、取り出すことで、抗原特異的リンパ球を回収することができる。
