摘要:
A method of using at least one quantitative ratio of two different amyloid beta-peptides in a sample of a body fluid from a patient for determining the patient's probability of contracting Alzheimer's disease (AD) or for determining the patient's suffering from a precursor of Alzheimer's disease includes obtaining the sample of the body fluid from the patient. The at least one quantitative ratio is calculated from the two different amyloid beta-peptides from the sample. The patient's probability of contracting Alzheimer's disease (AD) or the patient's suffering from a precursor of Alzheimer's disease is calculated using the at least one quantitative ratio. The two different amyloid beta-peptides are selected from (a) Aβ(1-42), (b) Aβ(2-40) and (c) Aβ(2-42). The at least one quantitative ratio is selected from (a) Aβ(1-42)/(b) Aβ(2-40), (a) Aβ(1-42)/(c) Aβ(2-42), (b) Aβ(2-40)/(a) Aβ(1-42) and (c) Aβ(2-42)/(a) Aβ(1-42).
摘要:
A method of diagnosis of Alzheimer's disease comprising the steps of obtaining a sample selected from of a group of samples consisting of body fluid samples and tissue homogenate samples from a patient; of exposing the sample to an antibody directed against Amyloid-beta (Aβ) peptides; of separating a fraction of the sample bond to the antibody from a remainder of the sample not bond to the antibody; and of determining an amount of at least one species selected from a group of species consisting of species having molecular masses in a range of 3870 to 3895 Da, 4520 to 4545 Da, 4802 to 4836 Da, 4837 to 4871 Da, and 7720 to 7790 Da in the fraction of the sample bond to the antibody.
