Amyloid-Beta 1-x ELISA Kit (Human Specificity;  Detects Abeta1-40 & Abeta1-42; 3.55pg/ml Sensitivity, 96T)  

Sensitive and selective colorimetric ELISA kit to ABeta 1-x with assay range 7.81-500 pg/ml, 3.55 pg/ml sensitivity.  Highly selective to amyloid-beta 1-x (see data below).  This ELISA kits employs a monoclonal capture antibody that recognizes the N-terminus and a monoclonal detection antibody that binds near amino acid residue 20 in amyloid-beta:  This ELISA kit detects both Abeta1-40 and Abeta 1-42.

Lead time estimate:  2 weeks

Specifications:
  1. Complete ELISA kit in sandwich format.  Colorimetric detection at 450 nm.
  2. The ELISA plate is coated with an affinity purified monoclonal antibody that recognizes the N-terminus, and a monoclonal detection antibody that binds near amino residue 20.  This kit detects both Abeta40 and Abeta42.
  3. The kit detects amyloid-beta 1-x in EDTA-plasma, cerebrospinal fluids, serum, cell culture media or brain tissue extract.
  4. Incubation times:  Samples with plate;  overnight.  Detection antibody:  1 hr
  5. Assay range:  7.81 - 500 pg/ml.  Sensitivity:  3.55pg/ml

Background on Amyloid-Beta (1-x)

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 associated with Alzheimer’s disease.
