免疫组织化学 (IHC) 在临床队列中的使用对于确定生物标志物在临床实践中的效用至关重要。将生物标志物从实验室转化为临床的一个主要瓶颈是缺乏适合 IHC 的特征明确的特异性抗体。尽管 IHC 作为生物标志物验证工具得到广泛使用,但尚未制定普遍接受的标准化指南来确定特定抗体在使用前对 IHC 的适用性。在这篇综述中,我们讨论了使用免疫组织化学生物标志物所面临的技术挑战,并严格探索经典和新兴的抗体验证技术。根据我们对这些技术的审查,我们为免疫组织化学测定中使用的抗体的实用验证提供了严格的标准。免疫组织化学是生物标志物开发的重要工具。很少有潜在的免疫组织化学生物标志物能够达到临床应用。我们描述了影响 IHC 过程的各种因素。我们讨论经典和新兴的抗体验证技术。我们为正确的抗体验证提供推荐的工作流程。
The use of immunohistochemistry (IHC) in clinical cohorts is of paramount importance in determining the utility of a biomarker in clinical practice. A major bottleneck in translating a biomarker from bench‐to‐bedside is the lack of well characterized, specific antibodies suitable for IHC. Despite the widespread use of IHC as a biomarker validation tool, no universally accepted standardization guidelines have been developed to determine the applicability of particular antibodies for IHC prior to its use. In this review, we discuss the technical challenges faced by the use of immunohistochemical biomarkers and rigorously explore classical and emerging antibody validation technologies. Based on our review of these technologies, we provide strict criteria for the pragmatic validation of antibodies for use in immunohistochemical assays. Immunohistochemistry is an important tool for biomarker development. Few potential immunohistochemistry biomarkers reach the clinical utility. We describe the various factors influencing the IHC process. We discuss classical and emerging antibody validation technologies. We provide recommended work‐flows for proper antibody validation.
