Multiplexed immunofluorescence (IF) can be achieved using different commercially available platforms, often making use of conjugated antibodies detected in iterative cycles. A growing portfolio of pre-conjugated antibodies is offered by the providers, as well as the possibility for conjugation. For many conjugation methods and kits, there are limitations in which antibodies can be used, and conjugation results are sometimes irreproducible. The conjugation process can limit or slow down the progress of studies requiring conjugation of essential markers needed for a given project. Here, we demonstrate a protocol combining manual indirect immunofluorescence (IF) of primary antibodies, followed by antibody elution and staining with multiplexed panels of commercially pre-conjugated antibodies on the PhenoCycler platform. We present detailed protocols for applying the workflow on fresh frozen and formalin fixed paraffin embedded tissue sections. We also provide a ready to use workflow for coregistration of the images and demonstrate this for two examples.
多重免疫荧光(IF)可以使用不同的商业上可获得的平台来实现,通常利用在迭代循环中检测到的共轭抗体。供应商提供了越来越多的预共轭抗体,并且还提供了共轭的可能性。对于许多共轭方法和试剂盒,存在可以使用的抗体的限制,并且共轭结果有时不可重复。共轭过程可能会限制或减缓需要共轭特定项目所需的基本标记物的研究的进展。在这里,我们展示了一种结合手动间接免疫荧光(IF)的方案,该方案使用原始抗体,然后洗脱抗体,并在 PhenoCycler 平台上用预先商业化的多重共轭抗体进行染色。我们提供了在新鲜冷冻和福尔马林固定石蜡包埋组织切片上应用工作流程的详细方案。我们还提供了一个用于图像配准的即用型工作流程,并为此展示了两个示例。
