获得有关细胞上受体谱的信息,并随后找到这些信号受体的最有效配体,仍然是干细胞和癌症研究以及药物开发中的挑战性任务。我们介绍了一种在筛选表面受体和分析不同配体的结合力方面具有巨大潜力的活细胞方法。该技术基于分子力测定,这是一种单分子水平的并行格式、高通量实验。在人红细胞上,我们证明了 N-乙酰基-α-D-半乳糖胺基残基与凝集素螺旋凝集素的相互作用以及 CD47 受体与其抗体的相互作用。测量是在接近生理条件下进行的,并且仍然提供高度特异性的结合信号。此外,通过对两种不同形态的细胞类型进行详细的力比较分析,我们表明我们的方法甚至可以确定 CD47 受体与其抗体相互作用的 DNA 力当量。
Gaining information about receptor profiles on cells, and subsequently finding the most efficient ligands for these signaling receptors, remain challenging tasks in stem cell and cancer research as well as drug development. We introduce a live-cell method with great potential in both screening for surface receptors and analysing binding forces of different ligands. The technique is based on the molecular force assay, a parallel-format, high-throughput experiment on a single-molecule level. On human red blood cells, we demonstrate the detection of the interaction of N-acetyl-α-D-galactosaminyl residues with the lectinhelix pomatiaagglutinine and of the CD47 receptor with its antibody. The measurements are performed under nearly physiological conditions and still provide a highly specific binding signal. Moreover, with a detailed comparative force analysis on two cell types with different morphology, we show that our method even allows the determination of a DNA force equivalent for the interaction of the CD47 receptor and its antibody.
