產(chǎn)品介紹

Ghose法DNS試劑。又稱3,5-二硝基水楊酸法或簡(jiǎn)稱DNS法,DNS試劑是植物總糖和還原糖檢測(cè)(硝基水楊酸法)的成分之一,定量檢測(cè)植物組織樣品中的總糖和還原糖的含量。

注意事項(xiàng)：檢測(cè)原理是還原糖在堿性條件下被氧化成糖酸，3,5-二硝基水楊酸被還原為棕紅色的氨基化合物。在一定范圍內(nèi)，還原糖的量與棕紅色產(chǎn)物的顏色深淺程度呈一定比例關(guān)系。在540nm處測(cè)定棕紅色物質(zhì)的吸光度，該吸光度值與還原糖含量呈線性關(guān)系。

此產(chǎn)品濃度較高，溫度低容易析出，是主要成分析出，45-55℃水浴加熱一下即可，不影響使用。

儲(chǔ)存條件：	RT,避光（注意事項(xiàng)）
有效期：	12個(gè)月
用途：	本品僅供科研，不得用于其它用途。
注意：	部分產(chǎn)品我司僅能提供部分信息，我司不保證所提供信息的權(quán)威性，僅供客戶參考交流研究之用。
