A growing team of groundbreaking scientists around the world are now sharing their lab notebooks online
Production and purification of Ectodomain of SARS-CoV-2 Spike (S) protein Two different expression plasmids for prefusion S ectodomain residues 1−1208 of 2019-nCoV S (GenBank: MN908947) with proline substitutions (2P) at residues 986 and 987(1) and with six proline substitutions (HexaPro (at residues 817, 892, 899, 942, 986 and 987 (2), a “GSAS” substitution at the Read More …
Production and purification of recombinant SARS COV-2 RBDSD1-Fc protein from a transiently transfected EXPI293 mammalian cells. Expression plasmid for CoV-9-RBDSD1, residues of RBD R319−S591 with a C-terminal HRV3C protease cleavage site, a monomeric Fc tag and an 8XHisTag was generously gifted by Dr. McLellan’s lab (1). Secreted proteins were purified from a suspension culture cell Read More …
Over the last few months, we have all become familiar with the COVID-19 global pandemic. The coronavirus is “decorated” with the Spike (S) protein, one of the 25 proteins of SARS-CoV-2 that are encoded in the viral genome. The infection starts with the attachment of the virus to the cell membrane to enter host cells. Read More …
