Design of a highly thermotolerant, immunogenic SARS-CoV-2 ... pubmed.ncbi.nlm.nih.gov › 33429215 We describe a monomeric, glycan-engineered RBD protein fragment that is expressed at a purified yield of 214 mg/l in unoptimized, mammalian cell culture and, in contrast to a stabilized spike ectodomain, is tolerant of exposure to temperatures as high as 100 °C when lyophilized, up to 70 °C in solution and stable for over 4 weeks at 37 °C.
Receptor Binding Domain (RBD) SARS-CoV-2, Monomeric Made in CHO cells In 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.
