Amyloid-beta precursor protein (APP) is the source of the amyloid-beta (Ab) peptide found in neuritic plaques of Alzheimer’s disease (AD) patients.
APP is aglycosylated transmembrane protein with a long extracellular N-terminal domain, a short intracellular C-terminal domain, and an Abeta-segment of intermediate length shared between the intra- and extracellular regions.
APP is cleaved by alpha-secretase immediately before or after reaching the cell surface, releasing the nonamyloidogenic secreted form of the N-terminal soluble APP fragment (sAPPa).
APP molecules that are not cleaved by alpha-secretase are internalized, and subjected to beta-site cleavage by beta-secretase, leaving behind a membrane-bound C-terminal stub.
This terminal stub is the substrate for gamma-secretase, which cleaves the molecule at gamma-site(s) to release the 40aa, 42aa, or 43aa -long Ab peptides.
Applications:Suitable for use in Western Blot, Immunoprecipitation and Immunohistochemistry.
Other applications have not been tested.
Recommended Dilutions:Western Blot (Mouse): 1-3ug/ml.
Detects a band representing the full-length protein at ~ 100kD, and a band at ~ 10-12kD representing the C99 C-terminal cleavage fragment.
A major non-specific band has been observed at ~50kD in mouse brain homogenates
Digestion with trypsin prior to staining is required
Optimal dilutions to be determined by the researcher.
Storage and Stability:Store product at 4°C if to be used immediately within two weeks.
For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C.
Aliquots are stable at -20°C for 12 months after receipt.
Dilute required amount only prior to immediate use.
Further dilutions can be made in assay buffer.
Caution: FITC conjugates are sensitive to light.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Note: Applications are based on unconjugated antibody.
仕様
Size:100ul
Host:rabbit
Source Antibody:human
Grade:Affinity Purified
Purity:Purified by immunoaffinity chromatography.
Form:Supplied as a liquid in PBS, pH 7.2. No preservatives added. Labeled with Fluorescein isothiocyanate (FITC).
Specificity:Recognizes human Amyloid Precursor Protein. Reactivity has been confirmed with APLP2 (amyloid precursor-like protein 2) -/- knock-out and wildtype mouse brain homogenates and APP695 C99 (C-terminal fragment)-transfected HEK293 cell lysates by Western Blot. Negative control tests with APP -/- knock-out and APP/APLP2 double knock-out mice have confirmed the specificity of this antibody; neither of the target bands were identified in these test samples. Reactivity has also been confirmed with human Alzheimer’s brain tissue by immunohistochemistry. Species Crossreactivity: mouse.

Calc Applications Abbrev:IHC IP WB
Calc Crossreactivity:Hu Mo
Immunogen:Synthetic peptide derived from the C-terminal region of the human and mouse amyloid-beta precursor protein (APP695).
