Amyloid ß1-40 and ß1-42 peptides are involved in the appearance of Alzheimer's Disease symptoms. The production of these two amyloid peptides is regulated by the activity of 2 enzymes, ß and ? secretase, which cleave the amyloid precursor protein. This kit is intended to measure amyloid ß1-42 peptides in cell supernatant or in whole cells. The assay is a fast alternative to ELISA, thanks to the easy implementation of our Add and Read method.
