Soluble Amyloid Precursor Protein Alpha (sAPPα)
ELISA Kit (Human Specificity;  96T)
 
Sensitive and selective colorimetric ELISA kit to sAPPα with assay range 0.78-50 ng/ml.  Highly selective to sAPPα with virtually no cross reactivity with human sAPPβ.  The capture antibody is a monoclonal and its epitope is positioned at the "alpha" secretase cleavage site at the C-terminus of the sAPPalpha fragement.  The detection antibody is also a monoclonal and its epitope is positioned at the N-terminus of sAPPalpha.  96T
 
Fully guaranteed to meet specifications.

Specifications:
  1. Complete 96T ELISA kit in sandwich ELISA format.  Colorimetric detection at 450 nm.
  2. ELISA plate is coated with an affinity purified monoclonal capture antibody positioned at the C-terminus of sAPPalpha.  The detection antibody is also a monoclonal and its recognition domain is located at the N-terminus of sAPPalpha.
  3. The kit detects sAPPα in EDTA-plasma, cerebrospinal fluids, serum, and cell culture media.
  4. EIA buffer contains 1% BSA, 0.05% Tween 20 in PBS
  5. Incubation times:  Samples with plate;  overnight.  Detection antibody:  1 hr
  6. Assay range:  0.78 - 50 ng/ml;  0.09ng/ml sensitivity
  7. A related kit to sAPPbeta is also available:  click here

Background on sAPPα

Cleavage of amyloid precursor protein (APP) by “alpha-secretase” creates the extracellular soluble fragment known as sAPPα.  Because the “alpha-secretase” cleavage site is within the amyloid-beta molecule, generation of sAPPα by "alpha-secretase" prevents development of fibrillogenic amyloid-beta.  Generation of sAPPalpha may therefore be neuroprotective.  sAPPalpha may function in neuronal excitability, synaptic plasticity, synaptogenesis, neurite outgrowth, and cell survival.  In addition, sAPPalpha appears to modify potassium channels, N-methyl-D-aspartate receptors, and the transcription factor NF kappa B.


 
Methods Overview
