REACH authorisation
Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation:
Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10).
This means that the protein of interest is denatured.
If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.

The Amyloid Precursor Protein (APP) also known as amyloid protein is a transmembrane protein that is approximately 695 to 770 amino acids in length depending on the isoform. The molecular mass of APP can vary but typically falls around 100 to 140 kDa. It is heavily expressed in the central nervous system particularly in neurons but also in other tissues like muscle and kidney. The APP undergoes proteolytic processing which leads to the generation of various fragments including beta-amyloid peptides.
Biological function summary
The processing of APP plays a fundamental role in neuronal growth survival and repair. APP is cleaved into fragments that can regulate synaptic function and plasticity. It does not operate as a part of a complex but interacts with various cellular components. The protein participates in signaling pathways influencing cellular adhesion motility and neurite outgrowth. APP’s numerous interaction partners facilitate its involvement in different cellular processes highlighting its critical role in normal cell function.
Pathways
The APP is a central component in the amyloidogenic pathway where its cleavage by beta-secretase and gamma-secretase yields beta-amyloid. This pathway is one of two primary metabolic routes for APP—alternative enzymatic processing through the non-amyloidogenic pathway precludes beta-amyloid formation releasing peptides that do not aggregate. Enzymes like BACE1 (beta-secretase 1) and presenilin are important in the amyloidogenic pathway directly resulting in the production of the neurotoxic amyloid beta-peptide.
APP is intensely linked to Alzheimer's disease and cerebral amyloid angiopathy. Accumulation of beta-amyloid peptides formed from APP cleavage is a hallmark of Alzheimer's disease leading to plaque formation in the brain. This aggregation impacts neuronal function and is associated with neurodegenerative processes. Interactions with proteins like tau are significant as tau also plays an essential role in Alzheimer's disease pathology. Misprocessing of APP and the resulting beta-amyloid aggregates are also contributors to cerebral amyloid angiopathy where deposits within cerebrovascular walls compromise vascular integrity.
