|Application ||WB, IHC, IP|
|Calculated MW||35609 Da|
|Application & Usage||Western blotting (0.5-4 µg/ml) and immunoprecipitation (1-4 µg/ml). However, the optimal conditions should be determined individually. The antibody detects both phosphorylated and non-phosphorylated forms of IkBα.|
|Other Names||IkappaBalpha , MAD3, MAD-3, IKBA, NFKBI, IKB-alpha, I-kappa-B-alpha|
|Formulation||100 µg (0.25 mg/ml) immunoaffinity purified mouse monoclonal antibody in phosphate buffered saline (PBS), pH 7.2, containing 50% glycerol, 1% BSA, 0.02% thimerosal.|
|Handling||The antibody solution should be gently mixed before use.|
|Reconstitution & Storage||-20 °C|
|Precautions||IkBalpha Antibody (Clone 6A055) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||IKBA, MAD3, NFKBI|
|Function||Inhibits the activity of dimeric NF-kappa-B/REL complexes by trapping REL dimers in the cytoplasm through masking of their nuclear localization signals. On cellular stimulation by immune and proinflammatory responses, becomes phosphorylated promoting ubiquitination and degradation, enabling the dimeric RELA to translocate to the nucleus and activate transcription.|
|Cellular Location||Cytoplasm. Nucleus. Note=Shuttles between the nucleus and the cytoplasm by a nuclear localization signal (NLS) and a CRM1-dependent nuclear export.|

NF-kB is silenced in the cytoplasm by an inhibitory protein, IkB. IkB proteins are phosphorylated by IkB kinase complex consisting of at least three proteins, IKK1/α, IKK2/β, and IKK3/g. External stimuli such TNF-α or other cytokines results in phosphorylation and degradation of IkB releasing NF-kB dimers. NF-kB dimer subsequently translocates to the nucleus and activates target genes. Six members of IkB family members have been identified. One of the first gene induced following NF-kB activation is IkBα.
