New DNA, novel polypeptides and novel antibodies

摘要

The present invention is compared to the mRNA expressed in normal human brains and is selected from DNA having a nucleotide sequence of sequence 1 to 17 which is complementary to the RNA chain of the mRNA that is changing its expression in the brain of patients with Alzheimer's disease and DNA thereof A DNA fragment in which one or more bases are missing, but substituted with other bases or DNA or DNA is added to one or more bases, and DNA hybridized with the DNA, a polypeptide encoded by the DNA, the polypeptide The present invention relates to an antibody to recognize a peptide and the DNA, the polypeptide, and the diagnosis, treatment and research of an Alzheimer's disease patient using the antibody.
