Anti Amyloid Precursor Protein (APP N-terminus) [AN2] polyclonal antibody

Background

The Alzheimer amyloid precursor protein (APP) is an integral membrane protein expressed in many tissues and concentrated in the synapses of neurons. Its primary function is not known, though it has been implicated as a regulator of synapse formation and neural plasticity. APP is best known and most commonly studied as the precursor molecule whose proteolysis generates amyloid beta (Aβ), a 39- to 42-amino acid peptide whose amyloid fibrillar form is the primary component of amyloid plaques found in the brains of Alzheimer’s disease patients. Isoform APP695 lacking the protease inhibitor domain is the predominant form in neuronal tissues. An antibody (named AN2) against the -terminus of human APP (aa 18~38) was raised in rabbit.

Data Link: Swiss-Prot P05067

Application

1) Western blotting (dilution: 1/3,000-1/1,000)
2) Immunocytechemistry (dilution: 1/1,000-1/500)
Other applications have not been tested.


<
Western blotting >
Human NT2 neurons infected with adenovirus expressing β-galactosidase (lane 1) or wild-type APP (lane 2) were analyzed by Western blotting using this antibody. Wild-type APP was abundantly expressed in NT2 cells (ref.3).


<Immunocytochemistry >
Mouse dorsal root ganglion cells were treated with this antibody to examine neuronal APP expression (ref.4).

<Reference>
This antibody has been used in ref.3 and 4.
