Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays) Three samples of known concentration were tested six times on one plate to assess intra-assay precision.
Spike Recovery
The spike recovery was evaluated by spiking 3 levels of Mammal BACE-1 into health serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 102% to 113% with an overall mean recovery of 104%.

Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated for the presence of BACE-1 in this assay. No medical histories were available for the donors.
Product Data Sheet
Background: BACE-1
BACE-1 (beta‑site APP cleaving enzyme-1) is an aspartic protease and an integral membrane protein. It is the major beta secretase, and together with the gamma secretase, is responsible for generating the amyloid beta peptide (A beta ) from the amyloid precursor protein (APP). Because A beta is a major component of amyloid plaques, BACE-1 has been implicated in the onset and/or progression of Alzheimer's disease. High levels of BACE-1 activity are sufficient to elicit neurodegeneration and neurological decline in vivo, indicating that inhibiting BACE-1 may block not only A beta -dependent but also A beta -independent pathogenic mechanisms. In addition to APP, BACE-1 also cleaves APP-like proteins 1 and 2, the cell adhesion protein P-selectin glycoprotein ligand-1 and beta -galactoside alpha 2,6-sialyltransferase, implying that BACE-1 may have additional functions involving the ectodomain shedding of membrane proteins.
