IL1RA Antibody – Rabbit Polyclonal

Figure 1. Western blot analysis of IL1RA using anti-IL1RA antibody (MBS1750454).
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 Hela whole cell lysate,
Lane 2: human COLO-320 whole cell lysate,
Lane 3: human HepG2 whole cell lysate,
Lane 4: human Jurkat whole cell lysate,
Lane 5: human K562 whole cell lysate,
Lane 6: human HT1080 whole cell lysate,
Lane 7: human U20S whole cell lysate,
Lane 8: human PANC-1 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-IL1RA antigen affinity purified polyclonal antibody at 0.5ug/mL overnight at 4 degree 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 IL1RA at approximately 23KD. The expected band size for IL1RA is at 20KD.
