cord-316723-srenbxa7	Zhao, Jincun	Development and evaluation of an enzyme-linked immunosorbent assay for detection of antibodies against the spike protein of SARS-coronavirus	2004-11-23		.txt	text/plain	3093	180	64	Amino acid residues 450–650 of the spike (S) glycoprotein of SARS-CoV (S450-650) contains dominant epitopes for anti-viral antibodies (Abs) in patient sera. However, so far there is no enzyme-linked immunosorbent assay (ELISA) available for easier and more sensitive detection of anti-S Abs. Our computer-assisted analysis suggested that amino acid residues 450-650 of the S glycoprotein (S450-650) of SARS-CoV is largely solvent accessible and likely to contain dominant B cell epitopes. (2004) showing that residues 441-700 of the S protein of SARS-CoV contained dominant epitope(s) for anti-S Abs in patient sera, as determined in WB assays. All patient sera were tested for anti-SARS-CoV IgG Abs using an ELISA kit produced by Huada Institute (see below). Sera from three convalescent SARS patients and two healthy individuals were serial diluted and tested in the S450-650-based ELISAs, which detected anti-S IgG Abs in a specific and sensitive manner, with the reactivity end point from 1:400 to 1:800 diluted patient sera (Fig. 2) .	./cache/cord-316723-srenbxa7.txt	./txt/cord-316723-srenbxa7.txt
