G Novel polypeptide selective binding with mouse immunoglobulin G or rabbit immunoglobulin G and uses thereof

摘要

The present invention relates to a novel polypeptide selectively binding to an immunoglobulin G of a mouse or a rabbit. More particularly, the present invention relates to a polypeptide binding to an immunoglobulin G of a mouse or rabbit, a polynucleotide encoding the polypeptide, A nucleotide-containing expression vector, a transformant into which the expression vector is introduced, a method for producing the polypeptide using the transformant, and a composition for immunoassay comprising the polypeptide. The novel polypeptide according to the present invention not only binds specifically to the immunoglobulin G of each mouse or rabbit and replaces the existing costly secondary immunoglobulin G and can be used in various biological immunoassays, It is useful for various immune sensor / immunization chip production and drug screening by using globulin G hybrid.
