Human Amyloid-Beta 1-42 ELISA Kit (96T)

Sensitive and selective colorimetric ELISA kit to ABeta (1-42) with assay range 12.5-800 pg/ml.  Highly selective to amyloid-beta 1-42 with minimal cross reactivity to amyloid-beta 1-40 (see data below).  The affinity purified polyclonal capture antibody is selective to the C-terminus at amino acid position 42 and the affinity purified monoclonal-HRP detection antibody recognizes an epitope near amino acid position 20 in Abeta 1-42.

A related and similarly configured ELISA kit to Abeta 1-40 is also available and can be purchased as a pair with this kit (see pull down menu).  

Specifications:
  1. 12.5 - 800 pg/ml assay range,  4.03 pg/ml sensitivity. 
  2. Complete ELISA kit in sandwich ELISA format.  Colorimetric detection at 450 nm.  96T
  3. ELISA plate is coated with an affinity purified polyclonal capture antibody that recognizes the C-terminus near position 42 of amyloid-beta 1-42.  The detection antibody is a monoclonal that recognizes an epitope near to amino acid position 20.
  4. The kit detects amyloid-beta 1-42 in EDTA-plasma, cerebrospinal fluids, serum, cell culture media or brain tissue extract.
  5. Incubation times:  Samples with plate;  overnight.  Detection antibody:  1 hr

Background on Amyloid-Beta (1-42)
Amyloid-beta (Abeta) is generated through amyloid precursor protein (APP) cleavage by secretases.  Beta-secretase cleaves an extracellular portion of APP and frees a soluble portion. Gamma-secretase cleaves APP within the transmembrane domain, creating amyloid-beta (Aβ) isoforms with lengths between 36-43 amino acid residues.  The prevailing isoforms of Amyloid-Beta are Aβ40 and Aβ42.  Aβ40 is the most widespread amyloid-Beta (Aβ) isoform, while Aβ42 is more fibrillogenic and is the principal Abeta peptide that may be associated with Alzheimer’s disease. 
 
We now also carry a line of ELISA kits with targets that appear to be associated with infection and inflammatory responses that may be associated with dimentia diseases.  For example, alpha-1-proteinase inhibitor (α1-PI), C-reactive protein (CRP), and leukocyte elastase (LE).  To locate this group of ELISA kits, enter the target name in the search bar.
