Specifications

Control Peptide for A2275-75S and A2275-75T. Human, A synthetic peptide consisting of 8aa of human beta 1-42 mapping within to the C-terminal. High degree of sequence homology with Mouse b-1-42. Demonstrates minimal sequence homology with b-1-40.
Catalog #A2275-74P
Alzheimer's Disease (AD) is a neurodegenerative disorder characterized by progressive loss of memory and cognition in the elderly. One of the most important and initial step involves proteolytic cleavage of amyloid precursor protein (APP, chromosome 21) releasing short 40, 42 & 43 aa peptides (beta amyloid1-40, 1-42, and 1-43). Polymerization of b-amyloid (Ab) and subsequent neuronal deposit (amyloid) leads to the degeneration of neurons involved in memory and cognition. Ab deposits have also been found to contain 2 additional proteins termed a-synuclein and b-synuclein. The 140 aa a-synucleins is identical with non-Ab component (NACP) of AD. The 134 aa human b-synuclein is homologous to 14kD bovine phosphoneuroprotein 14. Mutations in a-synuclein gene causing a replacement of alanine with a threonine may cause the protein to misfold. Synucleins are primarily expressed in the brain. At least 3 forms two large (140 aa SYN-1 & 149 aa SYN-2) and a small form (SYN-3, 42 aa) are produced by alternative splicing.
ApplicationsSuitable for use in ELISA and Antibody Blocking. Not suitable for use in Western Blot. Other applications not tested.
Recommended DilutionELISA: 50-100ng of control peptide/well.
Antibody Blocking: 5-10ug per 1ug A2275-75S (affinity purified antibody) or per 1ul A2275-75T (antiserum).
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 6 months at -20°C.
