Description :Rabbit Polyclonal Antibody
Specificity :Recognizes the IKK alpha protein with no cross response to IKKb or IKKg
Cited Applications :WB, ELISA, ICC, IF
Cross Reactivity :Human
Host / Isotype / Clone# :Rabbit, IgG
Immunogen :IKK alpha antibody was raised against a peptide corresponding to amino acids 716 to 734 of human IKK alpha, which differs from corresponding murine sequence by four amino acids.
Purification :Affinity chromatography
Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
Sample Data :Western blot analysis of IKK alpha in HeLa whole cell lysate with IKK alpha antibody at 1:1000 dilution.
Sample Data :Immunocytochemistry of IKK alpha in Jurkat cells with IKK alpha antibody at 1ug/ml.
Scientific Background :IKKalpha is a serine/threonine protein kinase that phosphorylates the I-kappa-B protein which is an inhibitor of the transcription factor NF-kappa-B complex. Phosphorylation of I-kappa-B protein triggers the degradation of the inhibitor via the ubiquitination pathway, thereby activating NF-kappa-B complex (1). IKKalpha is an essential regulator of NF-kappa-B-dependent gene expression through control of promoter-associated histone phosphorylation after cytokine exposure (2). IKKalpha is a critical component of the cytoplasmic transductional-transcriptional processor leading to induction of IFNalpha production. IKKalpha is also involved in the epidermis where it antagonizes mitogenic and angiogenic signals and represses tumor progression and metastases.
