單位定義
一個(gè)單位定義為在1X T4多核苷酸激酶反應(yīng)緩沖液中,37℃下30分鐘內(nèi)催化摻入1 nmol [ 32 P](ATP供體)的酶量。
質(zhì)量控制分析
單位表征測(cè)定
單位活性使用2倍系列稀釋法測(cè)量。在1X反應(yīng)緩沖液中制備酶的稀釋液,并將其加入到50μL含有10μMOligo dT單鏈DNA,1X PNK反應(yīng)緩沖液和66μMATP的反應(yīng)中,并將[γ- 32 P] ATP反應(yīng)在37°孵育30分鐘將其置于冰上,并使用Sambrook和Russell的方法(Molecular Cloning,v3,2001,pp.A8.25-A8.26)進(jìn)行分析。
蛋白質(zhì)濃度(OD 280)測(cè)量使用使用2.0mg / ml BSA樣品(Pierce Cat#23209)標(biāo)準(zhǔn)化的Nanodrop ND-1000分光光度計(jì)
在OD 280處分析2.0μL酶樣品并用產(chǎn)品儲(chǔ)存溶液沖切。使用消光系數(shù)63,440和分子量34,620道爾頓將觀察到的3個(gè)重復(fù)樣品的平均測(cè)量結(jié)果轉(zhuǎn)換為mg / mL。
SDS-Page(物理純度評(píng)估)
將2.0μL酶溶液加載到變性的4-20%Tris-甘氨酸SDS-PAGE凝膠上,其側(cè)翼為寬范圍MW標(biāo)記和2.0μL1:100稀釋的樣品。電泳后,將凝膠染色并比較??樣品以確定物理純度。該測(cè)試的驗(yàn)收標(biāo)準(zhǔn)要求濃縮樣品中污染帶的總量不超過稀釋樣品中目的蛋白質(zhì)條帶的質(zhì)量,確認(rèn)濃縮樣品的純度大于99%。
