Anti-Phospho-IκBα-Ser32/36 Antibody, clone 1I11 ZooMAb^® Rabbit Monoclonal

Quality Control Testing

Evaluated by Western Blotting with a construct containing N-terminal MBP-and C-terminal His-tagged recombinant I B protein fragment phosphorylated on serine 32 and 36.

Western Blotting Analysis (WB): A 1:10,000 dilution of this antibody detected a construct containing N-terminal MBP-and C-terminal His-tagged recombinant I B protein fragment phosphorylated on serine 32 and 36, but did not react with non-phosphorylated I B .

Tested applications

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Phospho-I B -Ser32 and 36 in HeLa cells treated with TNF .

Affinity Binding Assay: A representative lot of this antibody bound Phospho-IkB -Ser32/36 peptide with a KD of 8.4 x 10-6 in an affinity binding assay.

Peptide Inhibition Assay: Target band detection in a construct containing construct containing N-terminal MBP-and C-terminal His-tagged recombinant I B protein fragment phosphorylated on serine 32 and 36 was prevented by preblocking 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

NF-kappa-B inhibitor alpha (UniProt: P25963; also known as I-kappa-B-alpha, IkB-alpha, IkappaB alpha, Major histocompatibility complex enhancer-binding protein MAD3) is encoded by the NFKBIA (also known as IKBA, MAD3, NFKBI) gene (Gene ID: 4792) in human. I B is known to inhibit the activity of dimeric NF- B/REL complexes by trapping Rel dimers in the cytoplasm through masking of their nuclear localization signals. In most resting cells, NF- B is sequestered in the cytoplasm in an inactive form associated with I B , which blocks the ability of NF- B to translocate to the nucleus. However, following exposure to pro-inflammatory cytokines, UV light, reactive oxygen species, or bacterial and viral toxins, I B is phosphorylated by I B kinases (IKK) on serine 32 and 36 that allows its polyubiquitination and proteasomal degradation. This unmasks the nuclear localization signal of NF- B and allows it to translocate to the nucleus where it binds to NF- B response elements in target genes and regulates their transcription. In the nucleus, it can bind to NF- B and facilitate its nuclear export. I B can shuttle between the cytoplasm and nucleus through its nuclear import signal (aa 111-120) and nuclear export signal (aa 45-54). This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

KLH-conjugated linear peptide corresponding to 10 amino acids surrounding phosphoserines 32 and 36 in human I B .

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.

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
