Product Specifications

Immunogen

IkB-alpha (Tyr-305) synthetic peptide (coupled to KLH) corresponding to amino acid residues around tyrosine 305 of human IkB-alpha. This peptide sequence has low homology to other IkB proteins. [UniProt# P25963]

Modification

p Tyr305

Specificity

This antibody was cross-adsorbed to phospho-tyrosine coupled to agarose then affinity purified using phospho-IkB-alpha (Tyr-305) peptide (without carrier). The antibody detects a 38 kDa protein on SDS-PAGE immunoblots of A431 and Jurkat cells treated with pervanadate, but does not detect this band in control cells.

Clonality

Polyclonal

Host

Rabbit

Isotype

IgG

Theoretical MW

38 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Description

Stable for at least 1 year at -20°C.

Western Blot: IkB-alpha [p Tyr305] Antibody [NBP3-23390] -

Western Blot: IkB-alpha [p Tyr305] Antibody [NBP3-23390] - Western blot analysis of A431 cells treated with pervanadate (1 mM) for 30 min. Blots were probed with anti-IkB-alpha (lane 1), anti-IkB-alpha (Tyr-42) (NBP3-23389; lanes 2-5), or anti-IkB-alpha (Tyr-305) (NBP3-23390; lanes 6-9). In some lanes, the antibodies were used in the absence (lane 2 & 6) or presence of IkB-alpha (Tyr-42) (lane 3 & 8) or IkB-alpha (Tyr-305) (lane 4 & 7) blocking peptides, or BSA conjugated to phospho-tyrosine (lane 5 & 9).

Background: IkB-alpha

NF-kB is silenced in the cytoplasm by an inhibitory protein, IkB (1). Synthesis of IkBa is autoregulated (2). IkB proteins are phosphorylated by IkB kinase complex consisting of at least three proteins, IKK1/a, IKK2/b, and IKK3/g (3-6). External stimuli such as tumor necrosis factor 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 (1). One of the first gene induced following NF-kB activation is IkBa.
