Description
MyBioSource has just released new high-performing SAR-CoV-2 antigens for the development of COVID-19 IgG/IgM serology assays. The recombinant antigens are expressed in insect cells using proprietary expression and purification technologies. Expression in either insect cells provides for post-translational modifications such as glycosylation and phosphorylation which can offer significant performance advantages over E. coli expressed formats
