MONMOUTH JUNCTION, NJ.– United States Patent Application 20120107841 titled, “Serum Diagnostic Method, Biomarker and Kit for Early Detection and Staging of Alzheimer's Disease” cites Cleanascite™ from Biotech Support Group for lipid clarification. Cleanascite™ is used in this patent to remove lipids from serum samples. This patent describes a blood test which measures redox reactive autoantibodies before and after exposure to an oxidative agent in serum for the presence of an elevated level of redox-reactive autoantibodies for developing a laboratory method to screen, diagnose, monitor and/or stage early onset Alzheimer's disease.
Moreover, the patent describes the search for serological biomarkers of Alzheimer's disease (AD) by studying redox-reactive autoantibodies (R-RAA) present in serum which unmask antigen recognition sites upon oxidative exposure. The autoantibodies are detected in blood with an oxidizing agent and using a screening assay to detect antibodies that bind a self antigen. Hemin is the oxidizing agent used for R-RAA aPE ELISA. Inventor John Mcintyre developed technology to ‘unmask’ autoantibodies in serum samples in vitro and matched AD specific epitopes to reactive autoantibodies. The increase in R-RAA aPE in MCI serum samples and changes in hippocampal choline acetyltransferase (ChAT) in end-stage AD or MCI are being exploited as potential biomarkers. Using ELISA to quantitatively measure concentration of unmasked antibodies in serum samples in vitro by the presence of their recognition epitopes, the increase in R-RAA over their base line values and comparison to the increased ELISA reactivity in AD and/or normal individuals is determined. Comparisons between the AD and normal populations revealed highly significant differences in R-RAA antiphosphatidylethanolamine (aPE).
Characteristics of Cleanascite™
A high binding capacity for lipids with minimal cross-reactivity with proteins
Effectively replaces chlorinated/fluorinated hydrocarbons (eg. freon) and it is environmentally friendly.
Helps purify antibodies, recombinant proteins, nucleic acids, proteoglycans
Ideal for clarifying ascites, serum, cell & tissue culture, bile and organ homogenates
Very low protein binding
Does not bind to DNA, RNA, enzymes and proteins
