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.

Clone 2G2 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects IKKa/β phosphorylated on serine 176 and 180.

KLH-conjugated linear peptide corresponding to 13 amino acids surrounding phosphoserine 176 and 180 from human IKKa.

Quality Control Testing

Evaluated by Western Blotting in a construct containing GST-tagged recombinant IKK /β protein fragment phosphorylated on Ser176/180.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected a construct containing GST-tagged recombinant IKK /β protein fragment phosphorylated on Ser176/180, but did not detect in non-phosphorylated construct.

Tested applications

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected phospho-IKK /β-Ser176/180 in human colon cancer tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound Phospho-IKK /β- Ser176/180 peptide with a KD of 3.2 x 10-7 in an affinity binding assay.

Peptide Inhibition Assay: Target band detection in a construct containing GST-tagged recombinant IKKa protein fragment phosphorylated on Ser 176/180 was prevented by pre-blocking of a representative lot with the immunogen phosphopeptide, but not the corresponding non-phosphopeptide.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Inhibitor of nuclear factor kappa-B kinase subunit alpha (UniProt: O15111; also known as EC:2.7.11.10, I-kappa-B kinase alpha, IKK-A, IKK-alpha, IkBKA, IkappaB kinase, Conserved helix-loop-helix ubiquitous kinase, I-kappa-B kinase 1, IKK1, Nuclear factor NF-kB inhibitor kinase alpha, NFKBIKA, Transcription factor 16, TCF-16) is encoded by the CHUK (also known as IKKA, TCF16) gene (Gene ID:1147) in human. The activation of NF-kB by extracellular inducers depends on the phosphorylation and subsequent degradation of IkkB proteins. Activation of NF-kB is achieved through the action of a family of kB kinases (IKK). IKK contain two catalytic subunits (IKKa and IKKβ) and a regulatory/adapter protein IKK (NEMO). IKK and IKKβ play an essential role in NF-kB signal transduction that is activated by multiple stimuli. Their protein kinase domains are localized in amino acids 15-302 (IKK ) and 15-300 (IKKβ). Their leucine-zipper, localized in amino acids 455-476 (for IKKa) and 458-479 (for IKKβ), is important to allow for their homo- and hetero-dimerization. IKKa/IKKβ act as part of the canonical IKK complex in the conventional pathway of NF-kB activation and phosphorylate serine residues on IkBa and IkBβ. Although IKK and IKKβ share about 50% sequence homology, they can interchangeably phosphorylate Ser32/36 of IkBa and Ser 19/23 of IkBβ. These phosphorylation events lead to immediate polyubiquitination and degradation of IkB proteins and allow NF-kB to translocate to the nucleus where it activates the transcription of hundreds of genes involved in immune response, growth control, and protection against apoptosis. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.

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.

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.
