Study shows laboratory developed protein spikes consistent with COVID-19 virus

A new study has found that the key properties of the spikes of SARS-CoV-2 virus which causes COVID-19 are consistent with those of several laboratory-developed protein spikes, designed to mimic the infectious virus. The findings show how that viral spike manufactured through different methods in laboratories across the globe are highly similar and provide reassurance that the spike can be robustly manufactured with minimal variations between laboratories.
