生体細胞凍結前処理作業用キットであって、前記生体細胞凍結前処理作業用キットは、第1ステップ用生体細胞処理作業用プレートと、第2ステップ用生体細胞処理作業用プレートとを備え、
前記第1ステップ用生体細胞処理作業用プレートは、凹部を備え、前記凹部には、第1ステップ用生体細胞処理液が充填され、前記凹部の開口部は、剥離可能である封止シートにより封止されており、前記第2ステップ用生体細胞処理作業用プレートは、第1凹部と第2凹部を備え、前記第1凹部には、第2ステップ用の第1生体細胞処理液が充填され,前記第2凹部には、第2ステップ用の第2生体細胞処理液が充填されており、かつ、前記第1凹部の開口部および前記第2凹部の開口部は、剥離可能である封止シートにより、封止されており、
前記生体細胞凍結前処理作業用キットは、前記第1ステップ用生体細胞処理作業用プレートの前記凹部を被包する第1ステップ用生体細胞処理作業用プレート用蓋と、前記第2ステップ用生体細胞処理作業用プレートの前記第1および第2凹部を被包する第2ステップ用生体細胞処理作業用プレート用蓋とを備え、
前記第1ステップ用生体細胞処理作業用プレートおよび前記第2ステップ用生体細胞処理作業用プレートは、台座部と、前記台座部より上方に延びる環状壁部とを備え、前記環状壁部の内側に、前記凹部を備え、前記台座部は、前記環状壁部と前記台座部の外縁間に位置する上面部を備え、

本発明の生体細胞処理作業用プレート1aは、プレート本体2aを備え、プレート本体2aは、凹部8を備え、凹部8には、生体細胞処理液9が充填されており、さらに、凹部8の開口部は、剥離可能である封止シート4により、封止されている。
そして、上面部52aは、剥離用把持部42を用いた封止シート4の剥離作業時における、指による押圧が可能な押圧可能部を備えている。具体的には、上面部52aは、封止シート4の剥離作業時において、凹部8より手前側となる部分に手前側に延びる平面部を備えており、この部分は、指による押圧が可能であり、押圧可能部(押圧部位)として用いることができる。このため、例えば、左手指にて、上面部52aを押圧し、プレートを押さえた状態にて、剥離用把持部42を把持し、引き上げることにより、凹部に充填されている液体を流出させることなく、封止シート4を剥離できる。
台座部5a(環状脚部51a)の高さとしては、2~7mmが好ましく、特に、3~5mmが好ましい。また、環状壁部6aの高さとしては、1~5mmが好ましく、特に、1.5~4mmが好ましい。

また、剥離用把持部42の自由端となっている先端には、端部表示マーカ44が設けられている。 封止シート4、特に、シート本体部41としては、ガス難透過性シートが好ましい。このようなものであれば、凹部8に充填されている生体細胞処理液9の変性、濃度変化を抑制できる。封止シート4は、剥離用把持部42を含み、可撓性シートとなっている。
さらに、この実施例の生体細胞処理作業用プレート1aでは、蓋3aをプレート(プレート本体)2aより取り外すと、図3の状態となり、剥離用把持部42は、起き上がり、上面部52aの上面より離間し、把持可能となる。特に、この実施例の生体細胞処理作業用プレート1aでは、剥離用把持部42の自由端である端部は、プレート(プレート本体)2aの端部より延出した状態となり、把持がより容易なものとなる。
台座部5b(環状脚部51b)の高さとしては、1~5mmが好ましく、特に、1.5~4mmが好ましい。また、環状壁部6bの高さとしては、1~5mmが好ましく、特に、1.5~4mmが好ましい。
この実施例では、封止シート4a,4b,4cとしては、図10に示し、上述したものが好適に使用できる。
