Background of Presenilin-1

Presenilin-1 (PS-1) is a presenilin protein that in humans is encoded by the PSEN1 gene. Alzheimer's disease (AD) patients with an inherited form of the disease carry mutations in the presenilin proteins (PSEN1; PSEN2) or in the amyloid precursor protein (APP). These disease-linked mutations result in increased production of the longer form of amyloid-beta (main component of amyloid deposits found in AD brains). Presenilins are postulated to regulate APP processing through their effects on gamma-secretase, an enzyme that cleaves APP. Also, it is thought that the presenilins are involved in the cleavage of the Notch receptor, such that they either directly regulate gamma-secretase activity or themselves are protease enzymes. Several alternatively spliced transcript variants encoding different isoforms have been identified for this gene, the full-length nature of only some have been determined.

Antibody Validation

Figure 1. Western blot analysis of Presenilin 1/PS-1/PSEN1 using anti-Presenilin 1/PS-1/PSEN1 antibody (A00138-3).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human RT4 whole cell lysates,
Lane 2: human MCF-7 whole cell lysates,
Lane 3: human Caco-2 whole cell lysates,
Lane 4: rat brain tissue lysates,
Lane 5: mouse brain tissue lysates.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-Presenilin 1/PS-1/PSEN1 antigen affinity purified polyclonal antibody (Catalog # A00138-3) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for Presenilin 1/PS-1/PSEN1 at approximately 53 kDa. The expected band size for Presenilin 1/PS-1/PSEN1 is at 53 kDa.

Figure 2. IF analysis of Presenilin 1/PS-1/PSEN1 using anti-Presenilin 1/PS-1/PSEN1 antibody (A00138-3).
Presenilin 1/PS-1/PSEN1 was detected in an immunocytochemical section of RT4 cells. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (AR0022) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 5 μg/mL rabbit anti-Presenilin 1/PS-1/PSEN1 Antibody (A00138-3) overnight at 4°C. DyLight®488 Conjugated Goat Anti-Rabbit IgG (BA1127) was used as secondary antibody at 1:100 dilution and incubated for 30 minutes at 37°C. The section was counterstained with DAPI. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

Overlay histogram showing K562 cells stained with A00138-3 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-Presenilin 1/PS-1/PSEN1 Antibody (A00138-3, 1 μg/1x10⁶ cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (BA1127, 5-10 μg/1x10⁶ cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1 μg/1x10⁶) used under the same conditions. Unlabelled sample (Red line) was also used as a control.
