Mouse/Rat Amyloidβ (1-42) Assay Kit

Background: The first case of Alzheimer's disease was defined and reported in 1907 by the German scientist, Dr. A. Alzheimer. His studies have shown that this is the main cause of dementia in the elderly. The plaques which appear in the brains of Alzheimer's disease patients are mostly constituted by the Amyloidβ protein (Aβ). Aβ is a peptide which consists of 40 or 42 (43) amino acids, and reports show that this is cleaved from β- and γ- secretase from the amyloid precursor protein. APP is a trans-membrane protein consisting of 695, 751, or 770 amino acids. Reports have shown many variants of Aβ exist and are clarified into the culture supernatant from the APP cDNA transfected mouse neuroblastoma cell. Furthermore, in 1995, a dominant and differential deposition of distinct βamyloid peptide species, Aβ (N3pE), in senile plaques was found by Saido et al. This modified molecule, starting at the 3rd amino terminal residue, glutamate, was discovered to convert to pyroglutamate through intramolecular dehydration. This product is useful for measuring Aβ1-42 in blood sample (serum or plasma) of mouse or rat. Since this product hardly cross-reacts with human Aβ, it is useful for the measurement of mouse and rat Aβ1-42, when human Aβ is intermingled with the measurement sample.

Description:
This kit is a solid phase sandwich ELISA using 2 kinds of highly specific antibodies. Tetra Methyl Benzidine (TMB) is used as a coloring agent (Chromogen). The strength of coloring is proportional to the quantities of Mouse/Rat Aβ (1-42).

Product features:
The kit contains reagents for 96 determinations;
Microtiter plate consisting of 12x8;
Microtiter plate reader at 450 nm;
Analytical sensitivity: 0,05 pg/mL
