摘要

封面:在Vanderheiden等人(http://doi.org/10.1002/cpim.116)中,图像显示了用于测量SARS CoV-2中和抗体的高通量FRNT测定的概述。演示实验大纲的流程图。简而言之,将标本在37℃、5% CO2条件下连续稀释并与等量的icSARS-CoV-2混合1小时。然后,将免疫复合物混合物覆盖在Vero E6细胞上,在37℃和5% CO2下孵育1小时。将病毒接种物去除并用0.85%的甲基纤维素代替。感染的培养物在37℃、5% CO2条件下孵育24小时。之后,用多聚甲醛固定细胞,并探测SARS-CoV-2刺突蛋白。通过显色沉积观察病灶,使用CTL ImmunoSpot S6通用分析仪记录病灶,并使用Viridot进行定量。

Cover: In Vanderheiden et al. (http://doi.org/10.1002/cpim.116), the image shows overview of high-throughput FRNT assay for measuring SARS CoV-2 neutralizing antibodies. Flow chart demonstrating the experimental outline. In brief, the specimens are serially diluted and mixed with equal parts of icSARS-CoV-2 following 1 hr incubation at 37oC with 5% CO2. Then, the immune complex mixture is overlaid on top of Vero E6 cells and incubated at 37oC and 5% CO2 for 1 hr. The viral inoculum is removed and replaced by 0.85% methylcellulose. Infected cultures are incubated for 24 hr at 37oC with 5% CO2. After this, the cells are fixed with paraformaldehyde and probed for SARS-CoV-2 spike protein. Foci are visualized via chromogen deposit, recorded using CTL ImmunoSpot S6 Universal Analyzer, and quantified using Viridot.
