    鈉離子交換柱法測氨基酸--

    RG011,OD104,皮克林/Pickering柱后衍生

    OPA 用于衍生分析氨基酸是1971年首次提出。圖 1 OPA 與一級(jí)氨基酸的反應(yīng)方程式。

     室溫下, OPA (Pickering O120) 在巰基乙醇(Pickering 3710-2000)環(huán)境中與一級(jí)氨基酸于 1 min 內(nèi)即可生成具有強(qiáng)熒光的異吲哚衍生產(chǎn)物。OPA 本身不發(fā)熒光的特性使其在色譜分離時(shí)不形成干擾峰。OPA 只能與經(jīng)次氯酸鈉等氧化劑氧化開環(huán)后的二級(jí)氨基酸反應(yīng),也可與 FMOC - Cl 聯(lián)用衍生二級(jí)氨基酸。OPA 衍生法因樣品制備簡單、衍生反應(yīng)迅速、靈敏度高及易于實(shí)現(xiàn)自動(dòng)化操作等優(yōu)點(diǎn)而成為柱前衍生反相高效液相色譜法中使用廣泛的方法。

    OPA 衍生法(用于檢測一級(jí)氨基酸)

    試劑: 300 mg OPA Pickering O120, 2 g Thiofluor? (Pickering 3710-2000), 3 mL 30 % Brij® 35 溶于 950 mL OPA稀釋液(Pickering OD104)

    反應(yīng)器: 45 °C, 0.15 mL

    衍生試劑流速: 0.3 mL/min

    檢測器: 熒光檢測器

    λex= 330 nm, λem=465 nm
