泛素樣特異性蛋白酶1(ULP1)特異性地切割Smt3p蛋白標(biāo)記物;對(duì)于細(xì)胞周期的進(jìn)展是必需的;與核孔蛋白結(jié)合,并且可能在末期與隔膜環(huán)相互作用;在應(yīng)激條件下被隔離到核仁中。別名:NIBI。
艾美捷抗ULP1抗體:
貨號(hào):AB702
物種交叉反應(yīng)性:人
來(lái)源:雞
應(yīng)用:Western Blot
推薦抗體稀釋度:
Western Blot:當(dāng)抗體最終濃度為5ug/mL時(shí),可有效檢測(cè)到500ng的重組蛋白。
儲(chǔ)存:-20℃保存;避免反復(fù)凍融。提供于pH 7.4的磷酸鹽緩沖液中。
別名:NIB1
分子量:72kDa

左圖:將0.5或5.0ug的ULP1涂覆在ELISA板上。隨后,洗去未結(jié)合的蛋白質(zhì),并用牛血清白蛋白(BSA)封閉。使用1.54ug/mL的AB703通過(guò)傳統(tǒng)ELISA檢測(cè)試劑檢測(cè)ULP1。二抗:α-雞HRP(1:5000)。陰性對(duì)照1:無(wú)AB4010;陰性對(duì)照2:無(wú)檢測(cè)試劑。二抗:α-雞HRP(1:5000)。
右圖:將不同量的ULP1加載到SDS-PAGE凝膠上,隨后進(jìn)行Western Blot檢測(cè)。使用7.71ug/mL的AB4010檢測(cè)印跡。
