Abstract
Provided are compositions and methods useful in the diagnosis of Alzheimer's Disease (AD). The methods involve immunologically testing biological samples for an amount of high molecular weight kininogen (HK) and cleaved high molecular weight kininogen (HKc), wherein determining less HK relative to a normal control, or determining more HKc relative to a normal control, or a combination thereof, aids in diagnosis of AD. Hybridomas and monoclonal antibodies bind with specificity to either HK alone, or to both HK and HKc. Kits for use in immunological AD testing using the mAbs are also provided.
Claims3
A method for aiding in the diagnosis of Alzheimer's Disease (AD) comprising testing a plasma sample obtained from a human subject suspected of having or at risk for developing AD, wherein the testing comprises using an enzyme-linked immunosorbent assay (ELISA) for high molecular weight kininogen (HK) and cleaved high molecular weight kininogen (HKc) using a capture antibody in the ELISA that is a hamster antibody that binds with specificity to a peptide consisting of the sequence IQSDDDWIPDIQIDPNGLSC (SEQ ID NO:6) and determining less HK relative to a normal control, or determining more HKc relative to a normal control, or a combination thereof, to aid in diagnosis of AD.
