A. 裝置架設
1) 運轉功能確認
首先連接機體與電源供應器,並準備一廢液瓶。將排放管開口置入廢液瓶中,並加入適量二次水於機體上方拖盤內。打開電源,按下邦浦啟動鍵(綠色),檢查二次水是否經邦浦吸入且經排放管流入廢液瓶中。此時可同時檢查液體流速是否可藉邦浦速度調整鈕進行調整,以及按下脈衝按鈕(黃色)確認邦浦是否可間些性做動。
2) 安裝membrane
首先請先將孔狀金屬板及尼龍網片以二次水沾濕,並由下往上依序將孔狀金屬板及尼龍網片置於機體上方拖盤內,將以清洗溶液沾濕之membrane以蛋白質面朝上之方向放置於尼龍網片中央,再將適當開口(75x 60m m)之矽膠蓋片放置於membrane之上。將排放管開口置入廢液瓶中,按下邦浦啟動鍵(綠色)以去除多餘之溶液。此時在確認溶液排空後矽膠蓋片是否緊密吸附於尼龍網片上。若確認正常,最後加入數滴清洗溶液並觀察溶液是否可完全經membrane上之孔洞快速流出。
3) 安裝排放管
如圖所示,將支撐器插入機後方,並將排放管固定於支撐器上,使排放管末段超出支撐器卡榫。
B. 免疫染色流程
1) 封鎖(Blocking, 5分鐘)
首先將邦浦速度調整鈕設定至2,並且加入8毫升封鎖溶液在membrane上,按下邦浦啟動鍵使溶液進行循環反應,並確認此一循環反應過程中封鎖溶液能覆蓋整張membrane,5分鐘後將排放管開口置入廢液瓶中,以去除多餘之封鎖溶液。
2) 一級抗體反應(15分鐘)
首先按下脈衝按鈕並將邦浦速度調整鈕設定至2,並且加入8毫升一級抗體溶液在membrane上,按下邦浦啟動鍵使溶液進行脈衝式循環反應,15分鐘後將排放管開口置入廢液瓶中,去除多餘之一級抗體溶液(若需重複使用一級抗體溶液,只需將排放管開口置入乾淨離心管中進行回收即可)。
3) 二級抗體反應(15分鐘)
如同上述一級抗體反應步驟,加入8毫升二級抗體溶液在membrane上,按下邦浦啟動鍵及脈衝按鈕使溶液進行脈衝式循環反應,15分鐘後將排放管開口置入廢液瓶中,去除多餘之二級抗體溶液。
4) 清洗(Washing, 5分鐘)
將排放管開口置入廢液瓶中並移除機身上之支撐器,將清洗套件放置於矽膠蓋片上,並加壓使其黏附於矽膠蓋片上。將邦浦速度調整鈕設定至3,並且緩慢加入100毫升清洗溶液在membrane上,在所有清洗溶液流出機體至廢液瓶後將membrane取出浸泡於清洗溶液中等待訊號偵測。

Reaction speed by Western Q (Circulated Pulse Method) is several todozen times higher than one by traditional shaking method.
☞ Protocol adjustment such as increasing time or raising concentration may be necessary for immunostaining which requires overnight reaction by traditional method because of antibodies or samples
