• 介紹： N-(2-羥乙基)哌嗪-N’-(2-乙磺酸)，是可滿足于所有生物學(xué)研究的最佳緩沖液之一。絕大部分生理PHS下HEPES是一種兩性離子有機(jī)化學(xué)緩沖劑，屬于Good’s緩沖試劑之一，pH 6.0-8.5范圍內(nèi)的緩沖能力最強(qiáng)。HEPES應(yīng)用非常廣泛，包括：1）用作細(xì)胞培養(yǎng)的緩沖體系，常用工作濃度為10-25 mM；與無(wú)機(jī)碳酸氫鹽緩沖系統(tǒng)相比，在組織或者器官培養(yǎng)中表現(xiàn)出更好的pH控制能力。不像碳酸氫鹽，HEPES不為細(xì)胞供給營(yíng)養(yǎng)。只有當(dāng)需要長(zhǎng)時(shí)間在CO2培養(yǎng)箱內(nèi)處理細(xì)胞，才會(huì)加入培養(yǎng)基內(nèi)以增強(qiáng)緩沖能力。2）用作兩性電解質(zhì)溶液；HEPES能溶解兩性電解質(zhì)，制備＜1 pH單位寬度的pH梯度以用于等電聚焦電泳實(shí)驗(yàn)；3）用作電鏡觀察蛋白沉積技術(shù)合適的緩沖體系，因HEPES不會(huì)對(duì)金屬基板造成負(fù)面影響；4）可用作定量和選擇性測(cè)定抗原-抗體反應(yīng)的緩沖試劑。
