Antibody array for measuring a panel of amyloids
Described are assay methods, modules and kits useful in the detection, treatment and/or prevention of dementia and related conditions, including but not limited to Alzheimer's disease and mild cognitive disorders.
1. A multiplexed assay kit configured to monitor the disease progression of and/or efficacy of a treatment regimen for Alzheimer's-related dementia in a patient, said kit comprising (a) obtained two or more test samples from a patient undergoing said treatment regimen for Alzheimer's-related dementia, wherein said two or more test samples include (i) a first test sample obtained from said patient at time t and (ii) at least one additional test sample obtained at time (t+n), wherein n is an integer greater than 1; (b) an array of autoantibodies configured to measure the level(s) of each biomarker in a panel of biomarkers comprising Aβ 16, Aβ 17, Aβ 42, Aβ 40, Aβ 38, total tau, P-tau, and C-tau in said two or more test samples; and said kit configured to determine from said level(s) of said biomarkers in said panel and estimated plaque density, the progression of and/or efficacy of said treatment regimen in said patient.
2. The kit of claim 1 further comprising a radioactive diagnostic agent selected from the group consisting of AMYVID™ (Florbetapir), Pittsburgh Compound B, and combinations thereof.
3. A kit configured to detect plaques in the brain of a patient, said kit comprising (a) two or more test samples from a patient undergoing a treatment regimen for dementia, wherein said two or more test samples include (i) a first test sample obtained from said patient at time t and (ii) at least one additional test sample obtained at time (t+n), wherein n is an integer greater than 1; (b) an array of autoantibodies configured to measure the level(s) of each biomarker in a panel of biomarkers comprising Aβ 16, Aβ 17, Aβ 42, Aβ 40, Aβ 38, total tau, P-tau, and C-tau in said two or more test samples; and said kit configured to determine from said level(s) of said biomarkers in said panel and estimated plaque density, the presence and/or absence of plaques in the brain of said patient.
4. A multiplexed assay kit configured to diagnose Alzheimer's-related dementia and/or plaque formation in a patient comprising (a) a test sample from a patient; (b) an array of autoantibodies configured to measure a level of an autoantibody to a set of biomarkers in said test sample, wherein said set of biomarkers comprises Aβ 16, Aβ 17, Aβ 42, Aβ 40, Aβ 38, total tau, P-tau, and C-tau; and said kit configured to diagnose from said binding reagent array the presence, absence, and/or progression of Alzheimer's-related dementia and/or plaque formation in said patient.
5. The kit of claim 4 further comprising a radioactive diagnostic agent selected from the group consisting of AMYVID™ (Florbetapir), Pittsburgh Compound B, and combinations thereof.
6. A multiplexed assay kit configured to diagnose Alzheimer's-related dementia and/or plaque formation in a patient comprising (a) a test sample from a patient; and (b) an array of autoantibodies configured to measure a level of mRNA expression of biomarkers in said test sample, wherein said biomarkers comprise Aβ 42, tau, tau/Aβ 42, Aβ 40/Aβ 42, Aβ 38, Aβ 38/Aβ 42 and Aβ 34, wherein a change in the level of expression of the biomarkers in comparison to a healthy control indicates that the patient has an increased likelihood of having Alzheimer's-related dementia and/or plaque formation.
7. A multiplexed assay kit configured to monitor disease progression of and/or efficacy of a treatment regimen for Alzheimer's-related dementia in a patient, said kit comprising (a) two or more test samples from a patient undergoing said treatment regimen for Alzheimer's-related dementia, wherein said two or more test samples include (i) a first test sample obtained from said patient at time t and (ii) at least one additional test sample obtained at time (t+n), wherein n is an integer greater than 1; (b) an array of autoantibodies configured to measure the level(s) of mRNA expression of each biomarker in a panel of biomarkers comprising Aβ 42, tau, tau/Aβ 42, Aβ 40/Aβ 42, Aβ 38, Aβ 38/Aβ 42 and Aβ 34, in said two or more test samples; and said kit configured to determine from said level(s) of said biomarkers in said panel and estimated plaque density, the progression of and/or efficacy of said treatment regimen in said patient.
8. The kit of claim 7 further comprising a radioactive diagnostic agent selected from the group consisting of AMYVID™ (Florbetapir), Pittsburgh Compound B, and combinations thereof.
9. A multiplexed assay kit configured to detect plaques in the brain of a patient, said kit comprising (a) two or more test samples from a patient undergoing a treatment regimen for dementia, wherein said two or more test samples include (i) a first test sample obtained from said patient at time t and (ii) at least one additional test sample obtained at time (t+n), wherein n is an integer greater than 1; (b) an array of autoantibodies configured to measure a level of mRNA expression of biomarkers in each test sample, wherein said biomarkers comprise Aβ 42, tau, tau/Aβ 42, Aβ 40/Aβ 42, Aβ 38, Aβ 38/Aβ 42 and Aβ 34, and wherein a change in the level of expression of the biomarkers in comparison to a healthy control indicates the presence and/or absence of plaques in the brain of said patient.
