注意事項(xiàng)

用10毫升無(wú)菌組織培養(yǎng)級(jí)水重新配制凍干產(chǎn)品。攪拌混合。如果出現(xiàn)沉淀物，在冷卻條件下繼續(xù)攪拌數(shù)小時(shí)/一夜或超聲處理，簡(jiǎn)要使用超聲波水浴。然后，在3000 x g下離心10分鐘，并移除顆粒。之后重組凍干產(chǎn)品必須通過(guò)0.2µm過(guò)濾器過(guò)濾，以保持無(wú)菌。復(fù)原后，在4°C下儲(chǔ)存以供立即使用，或等份加入工作體積，并在-20至-10°C長(zhǎng)期儲(chǔ)存，最大限度地減少凍融循環(huán)解凍時(shí)可觀察到蛋白質(zhì)沉淀。為了消除這種情況，可以在3000×g的條件下離心10分鐘。
