General description

The transcription factor NFκB (Nuclear Factor κB) is involved in the expression and regulation of a number of important cellular and physiological processes such as growth, development, apoptosis, immune and inflammatory response, and activation of various viral promoters including human immunodeficiency virus long terminal repeats. NFκB represents a group of structurally related and evolutionarily conserved proteins related to the proto-oncogene c-Rel with five members in mammals that include Rel (cRel), RelA (p65), RelB, NFκB1 (p50 and its precursor p105), and NFκB2 (p52 and its precursor p100). NFκB/Rel proteins exist as homo- or heterodimers to form transcriptionally competent or repressive complexes. Although most NFκB dimers are activators of transcription, the p50/50 and p52/52 homodimers can repress the transcription of their target genes. The p50/p65 heterodimer of NFκB is the most abundant in cells.

Specificity

NFκB p65, Mr 65 kDa

Immunogen

Epitope: C-terminus
KLH-conjugated, synthetic peptide corresponding to the 13 C-terminal amino acids (C-DMDFSALLSQISS) of the p65 subunit of human NFκB containing an N-terminal cysteine for conjugation. The immunizing sequence is identical in mouse.

Application

Anti-NFκB p65 Antibody, CT is a Rabbit Polyclonal Antibody for detection of NFκB p65 also known as Nuclear factor NF-kappa-B p65 subunit & has been validated in EMSA, IP & WB.
Immunoprecipitation:
4 µg of a previous lot immunoprecipitated NFκB p65 from 500 μg of a human A431 carcinoma cell lysate.

Physical form

Format: Purified
Protein A chromatography
Purified rabbit polyclonal IgG in 0.014 M phosphate buffer, pH 7.6, 0.175 M NaCl, 0.07% sodium azide and 30% glycerol. Liquid at -20°C.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerolcontaining solutions to become frozen during storage.

Analysis Note

Control
Positive Antigen Control: Catalog #12-301, non-stimulated A431 cell lysate. Add 2.5µL of 2-mercaptoethanol/100µL of lysate and boil for 5 minutes to reduce the preparation. Load 20µg of reduced lysate per lane for minigels.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Nuclear factor-kappa B (NF-kappaB) plays an important role in UV-induced skin tumorigenesis. Activation of NF-kappaB by UV-irradiation is composed of two phases. The early phase culminates with maximal levels of DNA binding ability at 4 h postirradiation and is dependent

Lung epithelial cells are important barriers in the respiratory system that provoke inflammatory responses through nuclear factor (NF)-κB activation to prevent pathogens from invading the body.

Resistance to tamoxifen, a selective estrogen receptor modulator (SERM), involves changes that prevent apoptosis and enhance cell proliferation and survival. Paradoxically, estrogen treatment inhibits the growth of long-term tamoxifen-treated breast tumors. Because of the increasing use of raloxifene, another SERM

The primary goal of chemotherapy is to cause cancer cell death. However, a side effect of many commonly used chemotherapeutic drugs is the activation of nuclear factor-kappaB (NF-kappaB), a potent inducer of antiapoptotic genes, which may blunt the therapeutic efficacy

Resistance to endocrine therapies remains a major problem in the management of estrogen receptor-alpha (ER)-positive breast cancer. We show that inhibition of NF-kappaB (p65/RELA), either by overexpression of a mutant IkappaB (IkappaBSR) or a small-molecule inhibitor of NF-kappaB (parthenolide; IC(50)=500
