Description

General description

Rabbit anti-β-amyloid (22-35) antibody specifically recognizes β-amyloid (22-35), β-amyloid (25-35), β-amyloid (1-40) and β-amyloid (1-42) and does not react with β-amyloid (32-35) and β-amyloid (35-25) by ELISA. The antibody detects β-amyloid (1-40) by immunoblotting (approx. 4kDa). Staining of the β-amyloid (1-40) band in immunoblotting is specifically inhibited by the immunizing peptide.

Cleavage of the amyloid precursor protein (APP) by γ-secretase produces the small fragment amyloid β (Aβ) peptide. Cleavage of APP occurs mostly at residue 40 but to a lesser extent residue 42. The amyloid β peptide contains a ~100 kDa soluble N-terminal fragment, and intracellular C-terminal fragments (CTFs) bearing the complete Aβ domain.

Proteolytic cleavage of the amyloid precursor protein (APP) produces the small fragment amyloid β peptide. Cleavage of APP occurs mostly at residue 40 but to a lesser extent residue 42. Aggregates of amyloid β peptide are found deposited in the brains of Alzheimer′s patients.

Immunogen

synthetic peptide corresponding to amino acids 22-35 of human β-amyloid (1-40) fragment, conjugated to KLH. This sequence corresponds to amino acids 693-706 of the human amyloid precursor protein APP, and is identical in mouse and rat APP.

Application

Rabbit anti-β-amyloid (22-35) antibody can be used for ELISA at a concentration of 0.2-0.4μg/mL using β-amyloid peptide (22-35). The product can also be used for western blot at 0.25-0.5μg/mL using β-amyloid peptide (1-40).

Anti-β-Amyloid (22-35) antibody produced in rabbit has been used in:

• western blot
• dot-blot assay
• indirect enzyme linked immunosorbent assay (ELISA)

Biochem/physiol Actions

Secreted Aβ lead to synaptic and neuritic compromise and glial activation. Aggregates of amyloid β peptide are found deposited in the brains of Alzheimer′s patients. Aβ(25-35) and Aβ(22-35) fragments are highly toxic segments of β-amyloid peptides that promote inflammatory processes in astrocytes and fibrillary aggregation of Aβ, thus representing a promising therapeutic target for Alzheimer′s.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide and 1% bovine serum albumin.
