Highlights Improved yields of SARS-CoV-2 spike RBD through modification of DNA constructs and purification parametersTwo versions of RBD show different sensitivity in serology assaysYields of greater than 50 mg/l obtained under optimal conditionsMagnetic bead purification technology improves throughput of protein production.Protection against SARS-CoV-2 and SARS-related zoonotic coronaviruses with pandemic potential is urgently needed. To evaluate immunization strategies, we made nanoparticles displaying the receptor-b
