Protocols for SARS-CoV-2 infection in primary ocular cells and eye organoids

Here, we describe a series of protocols detailing the steps for evaluating SARS-CoV-2 infection in models of the human eye. Included are protocols for whole eye organoid differentiation, SARS-CoV-2 infection, and processing organoids for single-cell RNA sequencing. Additional protocols describe how to dissect and culture adult human ocular cells from cadaver donor eyes and how to compare infection of SARS-CoV-2 and the presence of SARS-CoV-2 entry factors using qPCR, immunofluorescence, and plaque assays. For complete details on the use and execution of this protocol, please refer to Eriksen et al. (2021).
