Applications Key: W=Western Blotting, IP=Immunoprecipitation, IHC-P=Immunohistochemistry (Paraffin), F=Flow Cytometry, ChIP=Chromatin IP,

Specificity / Sensitivity

RelB (D7D7W) Rabbit mAb recognizes endogenous levels of total RelB protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the carboxy terminus of human RelB protein.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of LNCaP cells (blue) and HDLM-2 cells (green) using RelB (D7D7W) Rabbit mAb. Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4412 was used as a secondary antibody.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded HDLM-2 (left) and LNCaP (right) cell pellets using RelB (D7D7W) Rabbit mAb.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human tonsil using RelB (D7D7W) Rabbit mAb.

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HDLM-2 cells and either 10 μl of RelB (D7D7W) Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human IAP2 promoter primers, SimpleChIP® Human IκBα Promoter Primers #5552, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using RelB (D7D7W) Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower). KARPAS cell line source: Dr. Abraham Karpas at the University of Cambridge.

IP

IP

Immunoprecipitation of RelB from Raji cell extracts. Lane 1 represents 10% input, lane 2 is precipitated with Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 and lane 3 is RelB (D7D7W) Rabbit mAb. Western blot was performed using RelB (D7D7W) Rabbit mAb. A conformation specific secondary antibody was used to avoid cross reativity with IgG.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human lung carcinoma using RelB (D7D7W) Rabbit mAb.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human colon carcinoma using RelB (D7D7W) Rabbit mAb.

Background

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).

RelB, which is generally activated by non-canonical signaling, forms heterodimers with either p50 or p52 NF-κB subunits to regulate transcription (12,13). RelB knock out mice have significant impairments toward inflammatory responses and hematopoietic differentiation (14,15).
