The Biosensis ApoE/Aβ Complex ELISA kit is a sandwich ELISA that allows the preferential measurement of ApoE/Aβ complexes. This kit consists of a pre-coated mouse monoclonal anti-Aβ capture antibody, a highly validated ApoE/Aβ complex standard that is pre-formed, lyophilised and ready for reconstitution, a biotinylated ApoE detection antibody, and horseradish peroxidase (HRP)-conjugated streptavidin and detection reagent. The addition of a substrate (3,3’,5,5’-tetramethylbenzidine, TMB) yields a coloured reaction product which is directly proportional to the level of ApoE/Aβ complex present in samples and protein standards. Importantly, a well-characteriaed and unique ApoE/Aβ complex is included as a standard. This complex is pre-formed and lyophilised, requiring only reconstitution with assay diluent prior to use.

The purpose of this kit is the in vitro qualitative measurement of ApoE/Aβ complexes in brain extracts and CSF samples from both transgenic mice and humans or primates, relative to a known ApoE/Aβ complex standard. This kit has not been tested for other sample applications.
