ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 5F3 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects NFkB2 (p100/p52). It targets an epitope within 16 amino acids from the N-terminal region.

Immunogen

KLH-conjugated linear peptide corresponding to 16 amino acids from the N-terminal region of human Nuclear factor NF-kappa-B p100 subunit.

Application

Quality Control Testing

Evaluated by Western Blotting in HeLa cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected NFkB2 (p100/p52) in HeLa cell lysate.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected NFkB2 (p100/p52) in Jurkat and HepG2 cell lysates.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected NFkB2 (p100/p52) in human small intestine and human testis tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound NFkB2 peptide with a KD of 4.5 x 10-8 in an affinity binding assay.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected NFkB2 (p100/p52) in HepG2 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-NFkB2 (p100/p52), clone 5F3 ZooMAb®, Cat. No. ZRB1250, is a recombinant Rabbit monoclonal antibody that targets p100/p52 of NFkB2 and is tested in Affinity Binding Assay, Immunocytochemistry, and Immunohistochemistry (Paraffin), and Western Blotting

Target description

Nuclear factor NF- kB p100 subunit (UniProt: Q00653; also known as DNA-binding factor KBF2, H2TF1, Lymphocyte translocation chromosome 10 protein, Nuclear factor of kappa light polypeptide gene (Gene ID: 4791) in human. NF kB is a pleiotropic transcription factor 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 the NF- kB family have been identified 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. In most resting cells, NF- kB is sequestered in the cytoplasm in an inactive form associated with inhibitory molecules, which blocks the ability of NF- kB to translocate to the nucleus and bind to DNA. In a conventional activation pathway, IkB is phosphorylated and degraded thereby liberating NF- kB to translocate to the nucleus. In a non-canonical activation pathway, CHUK/IKKA homodimer phosphorylates NFkB2/p100 associated with RelB, inducing its proteolytic processing to NFkB2/p52 and the formation of RelB-p52 complex that serves as a transcriptional activator. However, the p52-p52 homodimer acts as a transcriptional repressor. NFkB2 has dual functions such as cytoplasmic retention of attached NF- kB proteins by p100 and generation of p52 by a co-translational processing. p52 is shown to bind to the kB consensus sequence 5′-GGRNNYYCC-3′, located in the enhancer region of genes involved in immune response and acute phase reactions. Clone 5F3 detects both the p100 and p52 units. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form
