Estimating the term…
A multi-transmembrane protein antigen includes a polypeptide corresponding to an extracellular loop of the multi-transmembrane protein, the N-terminal and C-terminal of the polypeptide being fixed on a solid substrate or the N-terminal and C-terminal being attached to both ends of a linker to form a cyclic structure, an antibody specifically binding to the antigen or an antigen-binding fragment thereof, and a method for screening an antibody specifically binding to the antigen. The present invention may be usefully employed for effective production of antibodies for multi-transmembrane proteins that play important roles in disease-related phenomena such as cell signaling.
A multi-transmembrane protein antigen comprising a polypeptide corresponding to an extracellular loop of a multi-transmembrane protein, wherein an N-terminal and a C-terminal of the polypeptide are fixed on a solid substrate, or an N-terminal and a C-terminal of the polypeptide are attached to both ends of a linker to form a cyclic structure, wherein polypeptide corresponding to the extracellular loop of the multi-transmembrane protein is a polypeptide consisting of the amino acid sequence of SEQ ID NO:
