Application examples

Application examples Immunolocalization using anti-APP-C31 polyclonal antibodies

Sample: NT2 neurons
Fixation: 72 h after infection with adenovirus vector expressing Amyloid Precursor Protein Anti-APP-C31 antibody was used in dilution 1: 1000.
Left image: stained for the N-terminus of APP with P2-1, mouse monoclonal antibody specific for N-terminus of APP.
Center image: stained for chromosomal DNA (Hoechst). Right image: stained for C-terminus of the caspase 3 cleaved APP with anti-APP-C31 antibody (ACT1).
Most of APP-accumulating neurons with shrunken and fragmented nuclei contain ACT1-immunoreactivity (arrows), but non-neuronal cells are hardly labeled with ACT1 (arrowheads).

The tissue was fixed with 4 % formaldehyde and permalized with acetone at -20ºC, followed by blocking with 4 % non-fat milk and 5 % goat normal serum at 4°C/ON. Primart antibody was incubated at 1: 1000 1h/RT.

Background The Alzheimer Amyloid Precursor Protein (APP) is a transmembrane protein whose abnormal processing is associated with the pathogenesis of Alzheimer’s disease. APP695 lacking the protease inhibitor domain is the predominant form in neuronal tissues. APP695 is cleaved by caspases into the 664-residue amino (N)-terminal fragment that lacks the carboxyl C-terminal 31-residues (APPC31) and the 31-residues C-terminal fragment (APP-C31). Both fragments might be potent inducers of neuronal apoptosis. An antibody (named ACT1) against the N-terminus of caspase 3-generated APP C-terminal 31 aa of human APP695 (APP-C31 ) was raised in rabbit.
