Detection of Human/Mouse/Rat TRAF‑2 by Western Blot.
Western blot shows lysates of Raji human Burkitt's lymphoma cell line, SW3T3 mouse contact inhibited fibroblast cell line, and L6 rat myoblast cell line. PVDF membrane was probed with 0.25 µg/mL Mouse Anti-Human/Mouse/Rat TRAF‑2 Monoclonal Antibody (Catalog # MAB3277) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human TRAF-1, -2, -3, -4, -5, and -6 (2 ng/lane) were included. A specific band for TRAF-2 was detected at approximately 56 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
TRAF‑2 in HeLa Human Cell Line.
TRAF‑2 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human/Mouse/Rat TRAF‑2 Monoclonal Antibody (Catalog # MAB3277) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Tumor Necrosis Factor (TNF) Receptor-Associated Factors (TRAFs) are a family of adaptor proteins that interact with a wide range of cell surface receptors and participate in the regulation of cell survival, proliferation, differentiation, and stress response. TRAFs were identified by their ability to form complexes with TNF receptor superfamily members but more recently are reported to also bind to Toll/IL-1 receptor family members and mediate cellular signaling. Six members of the TRAF family have been identified. All TRAF proteins have a homologous C-terminal TRAF domain that can bind the cytoplasmic domain of receptors as well as other TRAFs. TRAFs 2‑6 have N-terminal RING and zinc finger domains that are involved in signaling downstream events. TRAF-2, also known as TNF Receptor-Associated Protein (TRAP), is a 501 amino acid, 56 kDa protein which interacts with the cytoplasmic domain of TNFR1, TNFR2 and CD40 to mediate the activation of NF-kappa-B and AP-1 family of transcription factors. TRAF-2 can self-associate as well as form heterodimers with TRAF-1.
