The scientists at 21st Century Biochemicals have been manufacturing high quality Aß peptides since 1994.  Every bioactive peptide we manufacture includes our exclusive MS CheckTM peptide sequencing by CID MS/MS which confirms the sequence is correct as indicated. 

Description:       Amyloid peptides, derived from amyloid precursor protein (APP), are thought to play a role in the development of the senile plaques associated with Alzheimer’s Disease.  The amyloid hypothesis presupposes that flaws in the processing of APP result in abnormally high levels of the longer, “stickier” forms of beta amyloid, known as Aβ42 and Aβ43, leading to aggregation of amyloid in the neuronal cell death and ultimately neuronal death.  Mutations in the structure of Aβ40 and related peptides as well as in some of the enzymes involved in the processing of APP have been shown to alter the processing of APP. The sporadic (i.e., non-genetic) form of the disease, however, is far more common, caused by aging in concert with a number of both genetic and environmental risk factors.

Other fragments, mutations and modified Aß available, please inquire. We can also manufacture beta amyloid peptides to order. Just email us at info@21stcenturybio.com for more information.
