Description
1.酵素サンプルおよび試薬を含む液体をプレートのウエルに加える。
2.(酵素反応用に)インキュベートする。
3.沈殿物質(通常はトリクロロ酢酸[TCA]、普通は5%の最終濃度)を加えて反応を停止させ、タンパク質を沈殿させる。
4.4℃または氷上でインキュベートする。
5.未反応または遊離成分を洗浄除去する。(遊離物を定量化することが必要な場合は回収する。)
6.沈殿物(フィルターに結合したもの)および/または濾過物(遊離物)
を計数する。
Electroscan ESEM3(Philips Electron Opticsから入手可能)を使用して、膜サンプルの湿潤性を評価した。処理したサンプルからの膜の一部分を凍結割断し(以下でさらに記載するように)、次いで断面を分析するために、5℃に冷却したペルティエステージに載せた。断面サンプルは、疎水性側を画像フレームの上部に向けた。ESEMチャンバーを、ポンプを用いて大気圧から5トールの設定圧力に圧力を下げ、次いで水蒸気で洗浄し、浸水用対照物を使用して10トールにした。次いで浸水用対照物を放出させた。チャンバーの圧力が再度5トールに達したとき、チャンバーを再度水蒸気で洗浄し10トールにした。この手順を3回続けて、チャンバー中の空気を水蒸気に交換した。次いでチャンバーの圧力を7トールに設定した。チャンバーの圧力およびステージの温度に対するわずかな制御を行って、液体状の水をサンプルの突出部に保った。膜が濡れた後に、代表的な画像を得た。500倍の倍率で15KVのビーム加速電圧を使用して、画像を得た。画像は、Orion Image Acquisition Systemによって得た。
