Technical Data
Tumor Necrosis Factor Receptor Associated Factor 3, CT (TRAF-3)
Tumor necrosis factor (TNF) receptor associated factors (TRAFs) are the major signal transducers for the TNF receptor superfamily and the interleukin-1 receptor/Toll- like receptor (IL-1/TLR) superfamily (1). TRAF3 was first identified by its interaction with CD40 and the Epstein-Barr virus transforming protein LMP1 (2,3). Several TRAF3 mRNA splice variants exist and some of these can activate the transcription factor NF- B (4). Besides CD40, TRAF3also interacts with the TRFR superfamily member lymphotoxin-b receptor (LTbR) in association with TRAF2 and the apoptosis inhibitors cIAP1 and Smac. It has been suggested that TRAF3 induces mitochondria-mediated apoptosis upon binding of the TNF family cytokine LIGHT by LTbR (5).

Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications have not been tested.

Recommended Dilution:
Western Blot: 1:1000 Detects a band at 64kD.
Immunohistochemistry (paraffin sections): 1:500-1:1000
Optimal dilutions to be determined by the researcher.

Positive Control:
3Y3cell lysate

Storage and Stability:

May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. 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.
