Forest musk deer (FMD; Moschus berezovskii) immunoglobulin G efficiently bound to streptococcal G protein (SPG) and weakly bound to staphylococcal A protein. The results suggested that horseradish peroxidase-conjugated SPG could be chosen as an enzyme-labeled antibody substitute and laid a foundation for immunologic research in FMD disease.
Keywords: enzyme-labeled antibody substitute; forest musk deer; immunoglobulin G; streptococcal G protein.
