中文摘要

靶抗原密度对CAR-T 细胞效力的核心作用,凸显了准确测量临床肿瘤样本中抗原水平的必要性。在此,我们提出了一种用于定量神经母细胞瘤骨髓转移细胞上六种细胞表面抗原密度的方案。我们描述了患者样本获取、流式细胞术panel开发、仪器设置和补偿的步骤,并详述了运行临床样本和数据分析的程序。关于本方案使用和执行的完整细节,请参阅Heitzeneder et al. (2022)。1。

The central role of target antigen density on chimeric antigen receptor T cell potency highlights the need for accurate measurement of antigen levels on clinical tumor samples.

Here, we present a protocol for quantifying antigen density for six cell-surface antigens on neuroblastoma cells metastatic to bone marrow.

We describe steps for patient sample acquisition, flow cytometry panel development, instrument setup, and compensation and detail procedures for running clinical samples and data analysis. For complete details on the use and execution of this protocol, please refer to Heitzeneder et al. (2022). 1 .
