同年國(guó)際抗體驗(yàn)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(diǎn)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(yàn)證。Uhlén博士認(rèn)為,驗(yàn)證抗體特異性是目前確??贵w持續(xù)可重復(fù)性最重要的步驟,確??贵w能特異性識(shí)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(shí)驗(yàn)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(yàn)證策略是抗體特異性和重復(fù)性驗(yàn)證不可或缺的起始步驟。
Madhusoodanan ( 2014年)和Rhodes & trickers ( 2008年)證實(shí),在用于驗(yàn)證抗體的所有方法中,敲除驗(yàn)證的可接受性和可信度都很高?;蚯贸?(Knockout, KO) 驗(yàn)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?yàn)樨?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(cè)試特異性抗體時(shí),特異性抗體不會(huì)產(chǎn)生信號(hào),但在野生型 (wild type, WT) 細(xì)胞系測(cè)試特異性抗體時(shí),特異性抗體會(huì)產(chǎn)生特異性目的蛋白信號(hào)。以這種方式,KO 驗(yàn)證作為真正的陰性對(duì)照,以確認(rèn)抗體對(duì)目的蛋白的特異性( bordeau等,2010年)。
Bioss高特異性KO驗(yàn)證抗體有常見(jiàn)的腫瘤、信號(hào)轉(zhuǎn)導(dǎo)、細(xì)胞凋亡等相關(guān)抗體,解決實(shí)驗(yàn)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(gòu)抗體時(shí)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(shí)驗(yàn)樣本和時(shí)間,加速科研成果產(chǎn)出。
