Western blot analysis of Galectin 2/LGALS2 using anti-Galectin 2/LGALS2 antibody (orb669233). 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 50ug of sample under reducing conditions. Lane 1: human U-87MG whole cell lysates. After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA 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-Galectin 2/LGALS2 antigen affinity purified polyclonal antibody (Catalog # orb669233) 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 Galectin 2/LGALS2 at approximately 15KD. The expected band size for Galectin 2/LGALS2 is at 15KD.

IHC analysis of Galectin 2/LGALS2 using anti-Galectin 2/LGALS2 antibody (orb669233). Galectin 2/LGALS2 was detected in paraffin-embedded section of human pancreatic cancer tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 2μg/ml rabbit anti-Galectin 2/LGALS2 Antibody (orb669233) overnight at 4°C.
