How to mix the best anti-SARS-CoV-2 cocktail
Neutralisation resistance generated by Spike (S) protein mutations in Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) poses a challenge to antibody therapies for COVID-19. Antibody cocktails targeting the S protein receptor binding domain (RBD) are one way to avoid viral neutralisation escape, however only certain antibody combinations are currently effective.…
