Receptor Binding Domain (RBD) SARS-CoV-2, Monomeric
Made in CHO cellsIn addition to stabilized trimeric spike proteins, we also offer the RBD domain produced in the same CHO cell system. The RBD protein is easier to produce and to purify and is therefore an ideal alternative for applications where costs are the driving factor. Please contact us to learn about our pricing per gram or mg of RBD protein.
