Snippet: The FFPE specimen-compatible rabbit and mouse anti-SARS-CoV-2 antibodies we 145 characterized here can be used to map the cellular targets of SARS-CoV-2 in various organs 146 using multiplex IFA in addition to detecting viral infection. RNAscope ISH is a relatively novel 147 ISH platform with high-sensitivity and low-background due to its unique "ZZ" probe design 148 (33).

Document: The FFPE specimen-compatible rabbit and mouse anti-SARS-CoV-2 antibodies we 145 characterized here can be used to map the cellular targets of SARS-CoV-2 in various organs 146 using multiplex IFA in addition to detecting viral infection. RNAscope ISH is a relatively novel 147 ISH platform with high-sensitivity and low-background due to its unique "ZZ" probe design 148 (33). This platform has been widely used to detect viruses both in human and animal tissues (27, 149 author/funder. All rights reserved.

The dual staining 154 we developed to detect SARS-CoV-2 viral antigen and RNA in the same FFPE section can more 155 precisely detect SARS-CoV-2 because a positive IHC or ISH signal alone may originate from 156 remaining free viral antigen or degenerating RNA fragments rather than from viral particles.
