    摘要: A method for conveniently detecting binding between the von Willebrand factor and glycoprotein Ib and a means to be used therein. The von Willebrand factor fixed in a reactor immobilized in a reaction vessel in the presence of bottrocetin is bound to a chimeric protein constructed by fusing the carboxyl terminal of a partial protein containing the von Willebrand factor-binding site of glycoprotein Ib with the amino terminal of the Fc region of an immunoglobulin molecule. Then the Fc region of the above immunoglobulin molecule is detected to thereby detect the binding between the von Willebrand factor and the glycoprotein Ib or inhibition of this binding.

    摘要: A method for producing a protein having an antithrombotic activity, which comprises replacing, in a protein that has an amino acid sequence having a homology of not less than 30% to the amino acid sequence of SEQ ID NO: 1 and forms a higher order structure composed of a first &bgr; strand (&bgr;1), a first &agr; helix (&agr;1), a second &agr; helix (&agr;2), a second &bgr; strand (&bgr;2), a loop, a third &bgr; strand (&bgr;3), a fourth &bgr; strand (&bgr;4) and a fifth &bgr; strand (&bgr;5) in this order from the amino terminus, at least one amino acid residue in a region from &agr;2 to &bgr;2 and/or a region from &bgr;3 to &bgr;4 so that electric charge of the amino acid residue is changed towards positive direction.
