Affinity of Streptococcal G Protein to Forest Musk Deer (Moschus berezovskii) Serum Immunoglobulin G.

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.
