beta-secretase 1 measurement https://pubmed.ncbi.nlm.nih.gov/31745860/ Quantification of the amount of beta-secretase 1 in a sample, typicallly cerebrospinal fluid. Beta-secretase-1 is an aspartic-acid protease important in the formation of myelin sheaths in peripheral nerve cells, and is thought to have a role in Alzheimer's disease pathogenesis. A measurement that quantifies the amount of beta-secretase 1 (BACE1) normally found in blood or cerebrospinal fluid.
