SFPQ Monoclonal Antibody

• Catalog Number: orb547986
• Category: Antibodies
• Description: SFPQ Monoclonal Antibody
• Species/Host: Rabbit
• Clonality: Monoclonal
• Clone Number: AECI-19
• Tested applications: ICC, IF, IHC, WB
• Reactivity: Human, Mouse, Rat
• Isotype: Rabbit IgG
• Immunogen: A synthesized peptide derived from human SFPQ DNA- and RNA binding protein, involved in several nuclear processes. Essential pre-mRNA splicing factor required early in spliceosome formation and for splicing catalytic step II, probably as an heteromer with NONO. Binds to pre-mRNA in spliceosome C complex, and specifically binds to intronic polypyrimidine tracts.

Western blot analysis of SFPQ expression in A431 cell lysate using anti-SFPQ antibody (orb547986). 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. 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-SFPQ antigen affinity purified polyclonal antibody (Catalog # orb547986) at 0.5 ug/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 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 (Catalog # orb90444) with Tanon 5200 system. A specific band was detected for SFPQ.
