Target description

Transcription factor p65 (UniProt: Q04206; also known as Nuclear factor NF-kappa-B p65 subunit, Nuclear factor of kappa light polypeptide gene enhancer in B-cells 3, NF-kB p65) is encoded by the RELA (also known as NFKB3) gene (Gene ID: 5970) in human. NF-kB is a pleiotropic transcription factor that is present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. Five members of NF-kB family have been described in mammalian cells: NF- B1 (p50/p105), NF- B2 (p52/p100), RelA (p65), RelB, and c-Rel that associate to form various homodimeric or heterodimeric combinations. They share a highly conserved Rel homology domain (RHD), which is responsible for DNA binding, dimerization, and interaction with IkBs. The p50/RelA (p65) heterodimer is the major NF- B complex in most cells. The activity of NF- B is tightly regulated by its interaction with inhibitory I B proteins. In most resting cells, NF- B is sequestered in the cytoplasm in an inactive form associated with inhibitory molecules such as I B , I Bβ, I B , p105, and p100. This interaction blocks the ability of NF- B to translocate to the nucleus and bind to DNA. Following exposure to proinflammatory cytokines, UV light, reactive oxygen species, or bacterial and viral toxins, the NF- B signaling cascade is activated, leading to the proteasomal degradation of I B. This allows the translocation of unmasked NF- B from the cytoplasm to the nucleus where it binds to NF- B response elements in target genes and regulates their transcription. In a conventional activation pathway, IkB is phosphorylated by I B kinases (IKKs) and degraded thereby liberating NF- B to translocate to the nucleus. The inhibitory effect of IkB on NF- B through retention in the cytoplasm is exerted primarily through the interaction with RelA (p65). Beside its activity as a direct transcriptional activator, p65 can also modulate promoters accessibility to transcription factors and thereby indirectly regulate gene expression. RelA (p65) undergoes phosphorylation at Ser 536, which stimulates acetylation on Lys 310 and interaction with CBP. This phosphorylated and acetylated form of p65 displays enhanced transcriptional activity. Although acetylation at Lys 122 can enhance its DNA binding activity, but acetylation at Lys 310 is required for its full transcriptional activity. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
