2020 年 1 月 28 日,英国剑桥和美国林肯:Abcam 和 LI-COR 欣喜地宣布,双方在同行评审期刊《生物化学杂志》(JBC)[1] 上发表了共同撰写的手稿,旨在提高整个生命科学行业的试剂可重复性标准。



• 支持生命科学行业将提高抗体可重复性作为当前重点
• 更新了30 年“经典”蛋白质组学技术的方法

2020 年 1 月 28 日,英国剑桥和美国林肯:Abcam 和 LI-COR 欣喜地宣布,双方在同行评审期刊《生物化学杂志》(JBC)[1] 上发表了共同撰写的手稿,旨在提高整个生命科学行业的试剂可重复性标准。Pillai Kastoori 等人的新论文Antibody Validation for Western blot: By the User, for the User就合适的抗体验证标准提出了最佳实践建议,并提供了通过 Western blotting 证明抗体特异性、专一性和可重复性的有效策略。

在过去的几年中,生命科学试剂(包括抗体 [2])的质量问题已影响到整个行业,并引发了全球可重复性危机。四年前,为了解决这一问题,Abcam 在其内部抗体验证中采用了多种先进技术,其中包括将基因敲除(KO)细胞系测试作为阴性对照。迄今为止,Abcam 已经使用该工具对 2500 多种抗体的特异性进行了验证,这在业内是前所未有的。Abcam 由此获得的深入知识和经验与 LI-COR 的 Western blotting 专业知识整合后得到了一些有价值的深刻见解,科学家们可通过 JBC 出版物了解这些内容。

Abcam 新产品开发部副总裁 Alejandra Solache 博士表示:
我们致力于为科学家们提供最优质的试剂,并全力支持旨在提高整个生命科学领域可重复性的计划。一致性和可重复性是我们进行大规模产品开发、生产和抗体验证不可或缺的要素,在知名期刊(例如 JBC)中分享我们的方法可以促使我们的合作伙伴和 LI-COR 的合作伙伴对行业产生更大的影响。我们希望这篇论文能为科学界提供有关 Western blotting 抗体验证的最新知识和专业技术。

论文的共同第一作者兼 LI-COR 的生物技术研发部科学家 Lakshmi Pillai-Kastoori 博士表示:


使用的抗体不一致会导致 Western blotting 和其他免疫测定法结果存在差异。研究人员需在 Western blot 实验过程中和不同 Western blot 实验之间持续取得可重复的结果。解决当前危机需要抗体供应商与研究人员协同努力,这也是我们与 Abcam 密切合作创作这篇论文的重要原因。

该出版物继 Abcam 最近推出 KO 细胞裂解液之后发表,Abcam 的细胞裂解液是市场上最大的可用产品组合,可提供适用于抗体验证和多种 western blotting 应用的经验证阳性和阴性对照样本。
