Western blot analysis of Presenilin 1/PS-1/PSEN1 using anti-Presenilin 1/PS-1/PSEN1 antibody (orb865718). 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 # orb865718) 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 # orb90503) 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.

IF analysis of Presenilin 1/PS-1/PSEN1 using anti-Presenilin 1/PS-1/PSEN1 antibody (orb865718). 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 (orb90553) 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 (orb865718) overnight at 4°C. DyLight®488 Conjugated Goat Anti-Rabbit IgG 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.

Flow Cytometry analysis of K562 cells using anti-Presenilin 1/PS-1/PSEN1 antibody (orb865718). Overlay histogram showing K562 cells stained with orb865718 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-Presenilin 1/PS-1/PSEN1 Antibody (orb865718, 1 μg/1x10^6 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (5-10 μg/1x10^6 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1 μg/1x10^6) used under the same conditions. Unlabelled sample (Red line) was also used as a control.
