Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, IHC-P=Immunohistochemistry (Paraffin), IF-IC=Immunofluorescence (Immunocytochemistry), F=Flow Cytometry
Specificity / Sensitivity
c-Rel Antibody detects endogenous levels of total c-Rel protein. Cross reactivity was not detected with other family members.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human c-Rel. Antibodies were purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from K562, Raji and 293 cells, using c-Rel Antibody.
Immunohistochemical analysis of paraffin-embedded human breast carcinoma using c-Rel Antibody in the presence of control peptide (left) or antigen-specific peptide (right).
Immunohistochemical analysis of paraffin-embedded Hodgkin's lymphoma, showing nuclear and cytoplasmic localization using c-Rel Antibody.

Confocal immunofluorescent analysis of HeLa cells, untreated (left) or TNFα-treated (#2169, 20 ng/ml for 20 min, right), using c-Rel Antibody (green). Actin filaments have been labeled with DY-554 phalloidin (red).
Transcription factors of the nuclear factor κB (NF-κB)/Rel family play a pivotal role in inflammatory and immune responses (1,2). There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus (9-11).
