  1. Twenty commercial mAbs against 20 GPCR ectodomains were purchased and tested individually on the VirD-GPCR arrays. Z-scores that were calculated for the intended targets of each mAb obtained on the VirD-GPCR arrays are shown. aVirD-ACKR3 was recognized as the top target with two off-targets, CALCR and GPR61
