TWEAK (TNFSF12/Apo-3L) is a member of the TNF superfamily of cytokines that are typically involved in immune regulation, inflammation, and apoptosis (1,2). TWEAK mRNA is expressed in a variety of tissues and cell lines, with higher levels observed in the heart, brain, skeletal muscle and within the immune system (1). Like other family members TWEAK is a type II transmembrane protein that can also be proteolytically processed to form a soluble cytokine. Soluble TWEAK is a weak inducer of apoptosis in some cell lines (1). The receptor for TWEAK, known as TWEAKR or fibroblast growth factor inducible 14 (Fn14), is a relatively small member of the TNF receptor family (3). TWEAK signaling has been associated with apoptosis, proliferation, migration, angiogenesis, and inflammation (4). Recent studies have suggested some therapeutic potential of TWEAK and its receptor signaling in regards to autoimmunity, cancer, and vascular injury (5-8).
Applications:
Suitable for use in Western Blot. Other applications not tested.
Recommended Dilution:
Western Blot: 1:1000. Incubate membrane with diluted antibody in 5% w/v BSA, 1X TBS, 0.1%
Tween-20 at 4 degrees C with gentle shaking, overnight.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
