Images & Validation

• Tested Applications: WB
• Dilution Range: Western blot, 0.1-0.5μg/ml, Human
• Reactivity: Human

Key Properties

• Antibody Type: Primary Antibody
• Host: Rabbit
• Clonality: Polyclonal
• Isotype: Rabbit IgG
• Immunogen: E. coli-derived human PREB recombinant protein (Position: K42-N236). Human PREB shares 87.7% amino acid (aa) sequence identity with both mouse and rat PREB.
• Target: Guanine nucleotide-exchange factor SEC12
• Molecular Weight: 45 kDa
• Purification: Immunogen affinity purified.
• Conjugation: Unconjugated

Storage & Handling

• Storage: Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
• Form/Appearance: Lyophilized
• Buffer/Preservatives: Each vial contains antibody formulated with stabilizing components, 0.9 mg NaCl, 0.2 mg Na2HPO4, and 0.05 mg NaN3. *This antibody is supplied in a stabilized formulation. Compatibility with conjugation reactions depends on the chemistry of the conjugation method used. For conjugation methods that are not compatible with the stabilizing components present in this formulation, a carrier-free antibody format is required.
• Concentration: Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.
• Expiration Date: 12 months from date of receipt.
• Disclaimer: For research use only

Western blot analysis of PREB using anti-PREB antibody. 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 50 ug of sample under reducing conditions. Lane 1: human Hela whole cell lysate, Lane 2: human placenta tissue lysate, Lane 3: human A549 whole cell lysate. 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-PREB antigen affinity purified polyclonal antibody 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 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit with Tanon 5200 system. A specific band was detected for PREB at approximately 45KD. The expected band size for PREB is at 45KD.
