Anti-APP Antibody Y188
|A synthetic peptide corresponding to residues in the NPXY motif of human Amyloid Beta A4 precusor (APP) was used as immunogen. This antibody specifically recognizes APP and its isoforms. It will not recognize either of the two Amyloid Beta Protein ( Aß4 )|

|Alzheimer’s disease (AD) is characterized by the presence of senile plaques in the brain and blood vessel walls. Amyloid Beta A4 (Aß4) protein has been found to be the principal constituent of senile plaques of AD’s patients (1-2). The amyloid beta-protein precursor (APP) is proteolytically cleaved to generate the 4 kDa Aß4 protein. Two variants of Aß4 can be detected; Aß1-40 “short-tailed” and Aß1-42 “long-tailed” (3-4). |

Immunohistochemistry (Paraffin-embedded sections) - Amyloid beta precursor protein antibody [Y188]; Ab32136, at a 1/250 dilution, staining Amyloid beta precursor protein by immunohistochemistry. .Positive immunohistochemical staining, using paraffin embedded human brain tissue (A). . Negative immunohistochemical staining, using human breast (B), skeletal muscle (C) and liver (D) tissues. .Tissues were stained in parallel on the same Normal Tissue Array.
Immunohistochemistry (PFA perfusion fixed frozen sections) - Anti-Amyloid beta precursor protein antibody [Y188]; ab32136, staining Amyloid beta precursor protein (green) in spinal cords from wild-type (left) or APP-/- (right) mouse embryos by Immunohistochemistry (PFA perfusion fixed frozen sections). . Embryos were fixed overnight in 4% paraformaldehyde at 4°C, permeabilized for 30 min in PBS containing 0.1% Triton X-100 and blocked for 4 h in PBS containing 3% normal donkey serum, 2% BSA, and 0.1% Triton X-100. Sections were incubated overnight at 4 °C with anti-APP antibody at 1/200 dilution. An AlexaFluor?488-conjugated donkey anti-rabbit IgG (1/200) was used as the secondary antibody.
Flow Cytometry - Anti-Amyloid beta precursor protein antibody [Y188]; Overlay histogram showing PC12 cells stained with ab32136 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody for 30 min at 22°C. The secondary antibody used was DyLight? 488 goat anti-rabbit IgG (H+L) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x10^6 cells) used under the same conditions. Unlabelled sample (blue line). Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in PC12 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
