Reagent kit containing polypeptide for use in detection of intermolecular interactions

Abstract

A reagent kit comprising a first polypeptide including a part in any one of amino acid sequences (A) to (C), and a second polypeptide including a part in any one of amino acid sequences (A) to (C), which are consistent of different sequences from a sequence of the first polypeptide; (A) an amino acid sequence in SEQ ID NO: 1 with deletion of an amino acid sequence from position 1 to 69 and an amino acid sequence from position 204 to 221,(B) an amino acid sequence in SEQ ID NO: 1 with deletion of an amino acid sequence from position 1 to 69 and deletion or substitution of at least one of amino acid residues at positions 146 to 156,(C) the amino acid sequence (A) or (B) with further deletion of at least one of amino acid residues at positions 70 to 74.
