Abstract
Description
・操作の成功は、オペレータの能力に大きく依存し、もしオペレータが正確に操作しないなら、過剰な液体と一緒に粒子を除去するおそれが高くなる。手順の成功率は、信頼性がなく、常に再現することができず、用いる緩衝液の種類に依存する。
・操作が比較的遅い。
・手順は、オペレータによる取扱中にサンプルが汚染するおそれを軽減するために、特別の注意、例えば、専用のピペットおよび二重フィルターが付いた汚染のないピペット先端の使用を必要とする。
・前述したように比較的高速で行われ(従って、比較的高応力を粒子に与える)遠心分離によって、粒子が損傷するおそれが比較的高くなる。
・DEPArrayTMによる選別
・他の種類の選別プロセス(顕微操作、光ピンセット、レーザー顕微切除、など)
・蛍光活性化細胞選別−FACS
・ピペットによる分注
・注射器による分注
の下流において用いることができる。
・全ゲノム増幅(WGA)
・全トランスクリプトーム増幅−WTA
・ポリメラーゼ連鎖反応−PCR
・(細胞の)固定、透過、および染色、またはそれらの組合せ
の上流において用いることができる。
・操作が極めて迅速かつ簡単である(これによって、とりわけ、汚染のおそれも低減される)。
・中空デバイス2が常に用いられ、その結果、(サンプルを損傷または逸失させる危険および汚染の危険を伴う)サンプルの危険な移送を行う必要がない。
・得られる結果が再現可能である(すなわち、得られる結果は、オペレータの能力に依存しない)。
・操作に無理がない。すなわち、サンプル(特に、細胞)は、大きな力を加えることなく、繊細に取り扱われる。
図10に示されている構造と同様の構造を得るために、略150μL中間デバイス2をアダプター21を備える2mL試験管(エッペンドルフ)に挿入した。緩衝液および細胞を含む38μLサンプルを中空デバイス2内に注入した。(実質的に図11,12に示されているように)、試験管を閉鎖し、2000rpmで2分間遠心分離を行った。
