Sample processing and single cell RNA-sequencing of peripheral blood immune cells from COVID-19 patients

Abstract

Summary: Single-cell RNA sequencing (scRNA-seq) of peripheral blood mononuclear cells (PBMCs) allows in-depth assessment of transcriptional changes in immune cells of patients with COVID-19. However, collecting, processing, and analyzing samples from patients with COVID-19 pose many challenges because blood samples may contain infectious virus, identification of immune cell subtypes can be difficult, and biological interpretation of analytical results is complex. To address these issues, we describe a protocol for sample processing, sorting, methanol fixation, and scRNA-seq analysis of PBMCs from frozen buffy coat samples from patients with COVID-19.For complete details on the use and execution of this protocol, please refer to (Yao et al., 2021).
