The invention relates to an antibody which binds to myelin oligodendrocyte glycoprotein (MOG), an antibody fragment thereof, a hybridoma which produces the antibody or the antibody fragment, a nucleic acid containing a nucleotide sequence which encodes the antibody or the antibody fragment, a transformant cell containing a vector containing the nucleic acid, a method for producing the antibody or the antibody fragment, a composition containing the antibody or the antibody fragment and a method for detecting or measuring an antigen that is present in the brain, a method for diagnosing or treating a brain disease, a method for improving the property of an antibody of accumulating in the brain and a method for increasing the amount of an antibody in the brain which use the antibody or the antibody fragment.

Antibody which binds to myelin oligodendrocyte glycoprotein

The present invention relates to a bispecific antibody in which an N-terminal side polypeptide is bound to an IgG portion that binds to TfR, a bispecific antibody fragment thereof, a DNA encoding the bispecific antibody or the bispecific antibody fragment thereof, a vector containing the DNA, a hybridoma and a transformant that produce the bispecific antibody or the bispecific antibody fragment thereof, a method for producing the bispecific antibody or the bispecific antibody fragment thereof, therapeutic and diagnostic agents containing the bispecific antibody or the bispecific antibody fragment thereof, therapeutic and diagnostic methods using the bispecific antibody or the bispecific antibody fragment thereof, and a reagent for detection or measurement containing the bispecific antibody or the bispecific antibody fragment thereof.

Bispecific antibody binding to TfR

An object of the present invention is to provide a bispecific antibody having an agonist activity to a GM-CSF receptor, and a bispecific antibody fragment thereof. The present invention relates to a bispecific antibody or a bispecific antibody fragment thereof containing: a first antigen-binding domain; and a second antigen-binding domain, in which one of the first antigen-binding domain and the second antigen-binding domain is an antigen-binding domain binding to CD116, and the other one is an antigen-binding domain binding to CD131.

Bispecific antibody that binds to CD116 and CD131

The invention relates to an antibody which binds to chondroitin sulfate proteoglycan 5 (CSPG5) or an antibody fragment thereof, a hybridoma which produces the antibody or the antibody fragment thereof, a nucleic acid comprising a nucleotide sequence encoding the antibody or the antibody fragment thereof, a transformant cell comprising a vector comprising the nucleic acid, a method for producing the antibody or the antibody fragment thereof, a composition comprising the antibody or the antibody fragment thereof, and a method for detecting or measuring an antigen present in the brain, a method for diagnosing or treating a brain disease, a method for enhancing the property of accumulating in a brain of an antibody, and a method for increasing the amount of an antibody in the brain, each of which using the antibody or the antibody fragment thereof, and the like.

Antibody binding to chondroitin sulfate proteoglycan 5

The invention relates to an antibody which binds to cell adhesion molecule 3 (CADM3) or an antibody fragment thereof, a hybridoma which produces the antibody or the antibody fragment thereof, a nucleic acid comprising a nucleotide sequence encoding the antibody or the antibody fragment thereof, a transformant cell comprising a vector comprising the nucleic acid, a method for producing the antibody or the antibody fragment thereof, a composition comprising the antibody or the antibody fragment thereof, and a method for detecting or measuring an antigen present in the brain, a method for diagnosing or treating a brain disease, a method for enhancing the property of accumulating in a brain of an antibody, and a method for increasing the amount of an antibody in the brain, each of which using the antibody or the antibody fragment thereof, and the like.
