Polyclonal F(ab’)2 fragments of equine antibodies raised against the spike protein neutralize SARS-CoV-2 variants with high potency

Summary: We used the recombinant trimeric spike (S) glycoprotein in the prefusion conformation to immunize horses for the production of hyperimmune globulins against SARS-CoV-2. Serum antibody titers measured by ELISA were above 1:106, and the neutralizing antibody titer against authentic virus (WT)...
