Product Description
Specificity / Sensitivity
Each antibody in the β-Amyloid Antibody Sampler Kit specifically detects either total APP protein or indicated modified/unmodified APP fragment. APP Antibody detects endogenous levels of several isoforms of both mature and immature amyloid beta (A4) precursor protein (APP), including APP695, APP770, and APP751. β-Amyloid (1-42 Specific) (D3E10), β-Amyloid (1-40 Specific) (D8Q7I), and β-Amyloid (1-37 Specific) (D2A6H) Rabbit mAbs recognize indicated Aβ fragments using human tissue and human APP transgenic mouse model tissue. The recommended usage of β-Amyloid (1-39 Specific) (D5Y9L) Rabbit mAb is limited to specifically detecting recombinant Aβ-39 fragments. β-Amyloid (D54D2) XP® Rabbit mAb recognizes endogenous levels of total human Aβ peptide using human tissue and human APP transgenic mouse model tissue. β-Amyloid (pE3 Peptide) (D5N5H) Rabbit mAb recognizes endogenous levels of pE3 Aβ peptide in human tissue and human APP transgenic mouse models.
Source / Purification
APP Antibody is a polyclonal antibody produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Thr668 of human APP695 protein. Antibodies are purified by protein A and peptide affinity chromatography. β-Amyloid fragment-specific monoclonal antibodies are produced by immunizing rabbits with synthetic peptides corresponding to residues at the carboxy terminus of each indicated human β-Amyloid fragment. β-Amyloid (D54D2) XP® Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human β-amyloid peptide (Aβ). β-Amyloid (pE3 Peptide) (D5N5H) Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human β-amyloid (pE3) peptide.
Background
Amyloid β (Aβ) precursor protein (APP) is a 100-140 kDa transmembrane glycoprotein that exists as several isoforms (1). The amino acid sequence of APP contains an amyloid domain, which can be processed and released by two-step proteolytic cleavage (1). The extracellular deposition and accumulation of the released Aβ fragments form the main components of amyloid plaques in Alzheimer's disease (1). Several fragments corresponding to progressive APP processing at alternative cleavage sites have been identified (2). These include Aβ (1-37), Aβ (1-39), Aβ (1-40), and Aβ (1-42) (2). These fragments can also be N-terminally modified to generate pyroglutamate-3 Aβ (pE3-peptide) (3). Fragment-specific and pan-Aβ antibodies are used to detect and examine relative levels of individual Aβ fragments.
