Extended Data Figure 1: Calu-3 cells bind Spike-RBD specifically and were engineered to express CRISPRi machinery.

Extended Data Figure 1:

a, Spike-RBD binding in different cell types at 20 nM and 200 nM Spike-RBD was quantified by flow cytometry. b, Expression of CRISPRi machinery (dCas9-BFP-KRAB) in the CRISPRi Calu-3 line indicated by the expression of BFP by flow cytometry.
