同年國際抗體驗證工作組 (IWGAV) 在Nature Methods期刊上在線發(fā)表題為「A Proposal for Validation of Antibodies」的文章,提出五點策略即:遺傳策略、正交策略、獨(dú)立抗體策略、表達(dá)標(biāo)記蛋白、免疫捕獲加上質(zhì)譜分析,以指導(dǎo)特定應(yīng)用中的抗體驗證。Uhlén博士認(rèn)為,驗證抗體特異性是目前確保抗體持續(xù)可重復(fù)性最重要的步驟,確??贵w能特異性識別其預(yù)期靶標(biāo),并持續(xù)保持相似的性能,從而讓所有按照既定實驗方案操作的使用者最終都能獲得相同的結(jié)果。IWGAV提出的這些驗證策略是抗體特異性和重復(fù)性驗證不可或缺的起始步驟。
Madhusoodanan ( 2014年)和Rhodes & trickers ( 2008年)證實,在用于驗證抗體的所有方法中,敲除驗證的可接受性和可信度都很高?;蚯贸?(Knockout, KO) 驗證基于KO樣品或細(xì)胞系的使用,KO樣品或細(xì)胞系是一種不表達(dá)目的蛋白的樣品或細(xì)胞系,因為負(fù)責(zé)編碼它的基因已經(jīng)被敲除或消除。在 KO 細(xì)胞系中測試特異性抗體時,特異性抗體不會產(chǎn)生信號,但在野生型 (wild type, WT) 細(xì)胞系測試特異性抗體時,特異性抗體會產(chǎn)生特異性目的蛋白信號。以這種方式,KO 驗證作為真正的陰性對照,以確認(rèn)抗體對目的蛋白的特異性( bordeau等,2010年)。
Bioss高特異性KO驗證抗體有常見的腫瘤、信號轉(zhuǎn)導(dǎo)、細(xì)胞凋亡等相關(guān)抗體,解決實驗中的重現(xiàn)危機(jī),不僅高保障產(chǎn)品質(zhì)量,還可以為科研人員在選購抗體時提供參考數(shù)據(jù),讓客戶能夠更快地找到穩(wěn)定可靠的抗體產(chǎn)品,節(jié)約科研工作者寶貴的實驗樣本和時間,加速科研成果產(chǎn)出。
