Abstract
This invention relates generally to a multimeric polypeptide complex/antigen which may be utilized in detecting or diagnosing diseases of the breast such as breast cancer. Furthermore, the invention relates to methods and kits, for example, which utilize this antigen or an antibody thereto. The complex itself comprises at least one BU101 polypeptide and at least one Mammaglobin polypeptide. In addition, the complex may comprise at least one polypeptide having at least 20% identity with the amino acid sequence of the BU101 polypeptide, the amino acid sequence of the Mammaglobin polypeptide, and fragments thereof.
Claims10
A purified multimeric polypeptide antigen (MPA) comprising at least one polypeptide (SEQ ID NO:6) and at least one Mammaglobin polypeptide (SEQ ID NO:5).
An assay kit for determining the presence of a multimeric polypeptide (MPA) or anti-MPA antibody in a test sample suspected of containing said antigen or anti-MPA antibody, said assay kit comprising a container containing a MPA polypeptide having an amino acid sequence selected from the group consisting of SEQ ID NO:5 and SEQ ID NO:6.
A composition of matter comprising a multimeric polypeptide antigen, wherein said antigen comprises at least one polypeptide (SEO ID NO:6) and at least one Mammaglobin polypeptide.
