巖藻糖Fucose特異性地與結(jié)合在α1,3中的蛋白質(zhì)N-聚糖上的巖藻糖殘基發(fā)生交叉反應(yīng)。這種殘基是植物蛋白N-聚糖的特征,在動(dòng)物蛋白N-聚糖中不存在。將該殘留物加入高爾基體中。
艾美捷巖藻糖Fucose:
貨號(hào):AS07-268
免疫原:核心巖藻糖殘基通過(guò)α1,3連接至N-糖鏈。
宿主:兔子
克隆性:多克隆
純度:免疫原親和純化的血清,溶于pH 7.4的磷酸鹽緩沖液(PBS)中。
形式:凍干
數(shù)量:50 ?g
復(fù)溶:復(fù)溶時(shí)加入50 ?l無(wú)菌水。
儲(chǔ)存:凍干品/復(fù)溶后儲(chǔ)存于-20°C;復(fù)溶后請(qǐng)分裝保存,避免反復(fù)凍融。打開(kāi)前請(qǐng)短暫離心管子,以避免因物質(zhì)粘附在管蓋或管壁上而導(dǎo)致的損失。
測(cè)試應(yīng)用:酶聯(lián)免疫吸附測(cè)定(ELISA)、免疫定位(IL)、西方印跡(WB)
推薦稀釋度:0.5 ?g/ml(ELISA),1:40(IL),1 ?g/10 ml(WB)
預(yù)期 | 表觀分子量:10 - 100 kDa(針對(duì)各種糖蛋白)
確認(rèn)的反應(yīng)性:高等植物、Phaeodactylum tricornutum(硅藻)
預(yù)測(cè)的反應(yīng)性:高等植物、Phaeodactylum tricornutum
未反應(yīng)的:目前尚未發(fā)現(xiàn)與預(yù)測(cè)反應(yīng)性不符的已知例外。

圖:抗巖藻糖抗體與PLA2(磷脂酶A2)和鏈霉親和素(Avidin)呈陽(yáng)性反應(yīng),而與去唾液酸胎球蛋白(asialofetuin)呈陰性反應(yīng)。這表明該抗體僅識(shí)別α1,3巖藻糖表位。
對(duì)于每份樣品,將1 ?g純化蛋白用Laemmli樣品緩沖液在100°C下變性10分鐘,隨后加載至4-12%的Bis-Tris凝膠上,并通過(guò)半干法轉(zhuǎn)印至硝酸纖維素膜,轉(zhuǎn)印時(shí)間為1小時(shí)15分鐘。膜在TBST中過(guò)夜飽和,期間不斷攪拌。膜在室溫下用TBST稀釋至1:5000的濃度,與一抗孵育2小時(shí),期間不斷攪拌。棄去抗體溶液,用TBST快速?zèng)_洗后,膜在TBST中洗滌3次,每次15分鐘。膜在TBST中稀釋至1:50,000的濃度,與二抗(山羊抗兔IgG,辣根過(guò)氧化物酶偶聯(lián),AS09 602,批號(hào)1707,來(lái)自AGRISE
