| Application Notes |
|---|
| This antibody is reactive to amino acid residues 17-24 of ß amyloid. The epitope lies within amino acids 18-22 of ß amyloid (VFFAE). 4G8 ß-amyloid antibody reacts to abnormally processed isoforms, as well as precursor forms. This antibody clone has been reported for use on IHC of free-floating sections in PBS containing 1% Triton incubated with 0.1 m citrate buffer (4). Additional reported applications (for the relevant formats) include: immunohistochemical staining on frozen tissue sections (IHC-F) and immunocytochemistry (ICC) |

| Structure | Amyloid precursor protein is a 770 amino acid protein with a molecular mass of ~100 kD. According to the UniProtKB database, APP (ID# P05067) has 11 isoforms (34 to ~90 kD) and the 770 form has been designated as the canonical form. Isoform APP695 is the predominant form expressed in neuronal tissue. Isoforms APP751 and APP770 are widely expressed in non-neuronal cells. Isoform APP751 is the most abundant form in T-lymphocytes. Aβ denotes peptides of 36-43 amino acids generated from cleavage of APP by secretases. Aβ has an apparent molecular mass of about 4 kD. |
|---|
| Distribution | Tissue distribution: Primarily nervous system, but also adipose tissue, intestine, and muscle. Cellular distribution: Cytosol, endosomes, nucleus, plasma membrane, extracellular, and golgi apparatus. |
|---|
| Function | The normal function of Aβ is not well understood. Several potential physiological roles have been proposed, including: activation of kinase enzymes; protection against oxidative stress; regulation of cholesterol transport; transcription factor, and as an anti-microbial agent. |
