本発明の容器状構造体の例を図1及び図2に示す。図1及び図2は、容器状構造体の断面図を示している。本発明の容器状構造体1は、第1の容器部aと、第2の容器部bとが自己融着材Xによって結合している。第1の容器部aと、第2の容器部bとが自己融着材Xによって結合することにより、全体として1つの容器を構成し、内部に単一の容器内部空間が形成される。
開口端12が閉鎖されることは、容器状構造体1内に完全閉鎖系を構築することができる点で好ましい。
本発明においては、自己融着材とは、半固体状態で存在することによって容易に変形し、且つ、自己同士が圧接されると互いに混ざり合って融着する性質(自己融着性)を有する物質をいう。このような性質により、自己融着材は僅かな隙間にも充填されることができ、接着剤や粘着材を用いなくとも対象物に隙間無く密着することができる。従って、自己融着材は開口端に密着することによって開口端を密閉することが可能である。
自己融着性は、例えば常温(例えば20℃±15℃)において呈されるものであってもよいし、加熱(例えば50~180℃又は50~150℃)によって呈されるものであってもよい。
自己融着材の層を容器に形成させる手段は、テープ状の自己融着材によるテーピングに限定されない。例えば自己融着材を揮発性有機溶媒に溶かし、その溶液を容器の対象部分に塗布することで自己融着材の層を形成させることができる。例えばブチルゴムはトルエン、キシレン、テトラヒドロフラン等の種々の揮発性有機溶媒に溶解し、高濃度では高粘度になるため、塗布による自己融着材層の形成が再現良く実施できる。乾燥後はテーピングによる方法と同様な自己融着性を発揮する。
本発明においては、容器状構造体の収容物を分割するために、収容物を有する容器状構造体自体を分割する。本発明では、工程(i)自己融着材の伸展、工程(ii)収容物の分割、及び工程(iii)第1の容器部と第2の容器部との切り離しを行うことによって、構造体を分割する。本発明の分割方法の工程を模式的に示した図を図3及び図4に示す。
図3に示す態様の場合、図3(iii)に示すように、さらにねじる(回転させる)ことによって、両容器部a及びb間の自己融着材Xの自己融着した部分をねじ切ることができる。この場合、ねじりながらさらに両容器部間を引き離すようにすると、容易にねじ切ることができる。
一方、図4に示す態様の場合、図4(iii)に示すように、切断手段32を用いて両容器部a及びb間の自己融着材Xの自己融着した部分(圧着面)を切断することができる。この場合、圧着面の凡そ中央を切断するとよい。
一方、その変形態様として、切断手段が圧着用部材とともに用意されることにより、切断と圧着との両機能を備えさせることもできる。その具体例を図5に示す。図5に例示する分割機構における切断手段32は、カッター本体41における切断端42を含む一部が一方の圧着用部材31L内に摺動可能な状態で収容されており、切断端42と反対の端に加圧ヘッド43を有するものである。加圧ヘッド43と圧着用部材31Lとの間にはバネ44が備えられている。他方の圧着用部材31Rには、切断端42を受容可能な凹部45が形成されている。
このように、容器状構造体の一部を、回収すべき収容物を外部雰囲気に接触させることなく分離することができる。
容器状構造体に収容されるべきものとしては特に限定されず、液体、固体、気体及び分散系からなる群から任意に1種又は複数種が選択される。
液体としては、水系液体及び非水系液体を問わない。分散系としては、組み合わせられる分散媒及び分散質はそれぞれ固体、液体及び気体のいずれであってもよい。分散系の具体例として、ゲル(ヒドロゲル及びオイルゲルを問わない)、ゾル、及び、カラム充填剤と展開溶媒とのスラリーなどが挙げられる。
この場合において、対象成分は、液体、固体、気体及び分散系中で操作されうる成分であれば特に限定されない。従って、天然物及び非天然物を問わず、生体内成分及び非生体内成分を問わない。
操作媒体としては、例えば、操作容器がクロマトグラフィー用カラム(図1(1-1)に例示の形状を有しうる)である場合、クロマトグラフィー用充填材剤及び展開溶媒(以下、これらを単にクロマトグラフィー用充填材剤と記載する場合がある)が挙げられる。図1(1-1)に記載のように、クロマトグラフィー用充填材剤3cが操作用容器部aに収容されうる。さらに、クロマトグラフィー用充填材剤3cの下端に位置するようにフィルター3sが収容されうる。回収用容器部bには、図1(1-1)に示すように何も収容されていなくてもよいし、対象成分を含む画分と混合させるべき液体などを収容していてもよい。
クロマトグラフィー用充填剤としては、逆相用ODSやゲル濾過担体などが挙げられるが、これらに限らず、当業者によって適宜選択されることができる。展開溶媒及び回収液も、当業者によって適宜選択される。
操作容器が図1(1-2)に例示の管状のものである場合、操作媒体としては、水系液体層及びゲル層が長手方向に交互に重層された重層物が挙げられる。より具体的には、操作用容器部a中に収容されている重層物の最下層は通常ゲル層2であり、その上に液体層3l及びゲル層3gが交互に重層される。回収用容器部b中の収容物4としては、水系液体であってもよいし、ゲルであってもよい。
オルガノゲルとしては、通常、非水溶性又は水難溶性である液体物質にゲル化剤を添加してゲル化することにより調製されたものが用いられうる。非水溶性又は水難溶性である液体物質としては、25℃における水に対する溶解度が概ね100ppm以下であり、常温(25℃±15℃)において液体状であるオイルが用いられる。たとえば、液体油脂、エステル油、炭化水素油、及びシリコーン油からなる群から1種又は2種以上が組み合わされて用いられうる。ゲル化剤としては、ヒドロキシ脂肪酸、デキストリン脂肪酸エステル、及びグリセリン脂肪酸エステルからなる群から選ばれる油ゲル化剤が1種又は2種以上組み合わされて用いられうる。
ヒドロゲルが、上記の水系液体と同様に対象成分が供される処理の環境を提供するものである場合(一例として、対象成分がタンパク質合成用基質である場合に、その対象成分からタンパク質を得る反応環境を提供するDNAヒドロゲル(P-ゲル))は、そのような処理に適した組成を有するように当業者によって適宜調製される。
また、操作容器が図1(2)に例示の形状である場合、上述の非水溶性又は水難溶性である液体物質にゲルーゾル転移機能を与えられた液滴封入媒体5の比重が1未満であれば、そこに加えられた水系液体は液滴封入媒体5に液滴3dとして沈み、容器内に収容される。液滴封入媒体5は、ゲル-ゾル転移温度を境として、温度制御で液滴を、移動可能な又は移動不可能な状態にすることができる。また、ゲル状態の液滴封入媒体には、その表面に窪みを形成することによって、その窪みに水系液体の液滴3d’を載せて保持することも可能である。
容器内に収容される液滴封入媒体5の量は、液滴3dを完全に封入することができる十分量であれば特に限定されない。具体的には、液滴の容量の1,0~10,000倍、或いは1,000~50,000倍の液滴封入媒体を用いることができる。
[5-1.クロマトグラフィー用カラムの場合]
図4に示すように、操作部Aにおいては、試料供給部12から投入された不純物を含む対象物質試料液30がクロマトグラフィー用充填剤3cにより分画され、対象成分の画分がフィルター3sによる濾過を経て回収部B内に落ちる。フィルター3sと回収液4との間には密封状態の空気層が存在しているため濾液はある程度回収部に落ちた後、回収部B内圧の上昇によって一定量で止まる。(もし、本発明の方法によらずに操作部Aと回収部Bとを分断すると、大気圧により、フィルターから再び濾液が直ちに落ち始める。この濾液が不純物を含む画分であると、不純物が回収部B内に流れ込んでしまう。)
その後、図4(i)~(iii)に示すように、本発明の方法を用いてカラムから回収部Bを分割することによって濾液を回収することができる。
以下、操作容器のうち操作管を用いたデバイス(キャピラリ状マイクロデバイス)及び矩形状(又は変形矩形状)容器を用いたデバイス(液滴操作デバイス)について述べる。いずれのデバイスも、対象成分を磁性体粒子に吸着させ、操作容器外部から磁場印加手段を用いて磁場を変動させることによって、対象成分の捕捉・運搬などの操作を行うことができる。
一方、磁性体粒子が予め操作容器内に収容されていない場合は、対象成分を有する試料中に混合された状態で操作容器内に供給される。
磁性体粒子が表面に有する親水性基としては、水酸基、アミノ基、カルボキシル基、リン酸基、スルホン酸基等が挙げられる。
操作管を用いた使用例として、核酸を対象成分として含む生体試料を、操作管内で核酸抽出及び洗浄を行う方法(図7)を以下に挙げる。当業者であれば、以下の例を参考にして、核酸以外の対象成分を所望の操作に供する手段を適宜選択することができる。
図7の操作管においては、操作用容器部aに、細胞溶解液(界面活性剤とグアニジンチオシアネート等のカオトロピック塩とを含む)3l1及び洗浄液3l2~3l4がゲルプラグ3g1~3g3及び2gと交互に重層された重層物収容され、空気層を介して、回収用容器部bに溶出液4が収容されている。
液滴操作デバイスの例として、核酸を対象成分として含む生体試料を、操作管内で核酸抽出、洗浄及び核酸増幅を行う方法(図8)を以下に挙げる。当業者であれば、以下の例を参考にして、核酸以外の対象成分を所望の操作に供する手段を適宜選択することができる。
核酸増幅反応が終了した後は、図8(i)に示すように、増幅産物を含む液滴71iが回収部B内へ移動され、本発明の分割方法を用いて回収部Bを操作部Aから取り外すことによって増幅産物を完全密閉状態で回収することができる。
