Product Type Specific: Protein kinase phosphosite-specific antibody

Antibody Code: PK659

Antibody Target Type: Phosphosite-specific

Antibody Phosphosite: T179+S180

Protein UniProt: O15111

Protein SigNET: O15111

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human IKKa (IkBKA) sequence peptide Cat. No.: PE-04AMV99

Antibody Immunogen Sequence: CC(pT)(pS)FVGT

Antibody Immunogen Description: Corresponds to amino acid residues C177 to T184; In the protein kinase catalytic domain activation T loop region between subdomains VII and VIII.

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Antibody Concentration: 1 mg/ml

Storage Buffer: Phosphate buffered saline pH 7.4, 0.05% Thimerasol

Storage Conditions: For long term storage, keep frozen at -40°C or lower. Stock solution can be kept at +4°C for more than 3 months. Avoid repeated freeze-thaw cycles.

Product Use: Western blotting | Antibody microarray

Antibody Dilution Recommended: 2 µg/ml for immunoblotting

Antibody Potency: Strong immunoreactivity of a target-sized protein by Western blotting in human lung. Medium-weak immunoreactivity of a target-sized protein by Western blotting in Jurkat, A431, A549, Hek293 and T98G cells. Very strong immunoreactivity with immunogen peptide on dot blots.

Antibody Species Reactivity: Human
Antibody Positive Control: The observed molecular mass of the processed target protein on SDS-PAGE gels is reported to be around 85-95 kDa.

Antibody Specificity: Medium-high

Antibody Cross Reactivity: In A549 cells, EGF increases an 85 kDa immunoreactive protein (probably target) and EGF decreases 75 kDa immunoreactive protein. In HEK-293 cells, phenylarsine oxide (PAO) decreases 100, 80 + 35 kDa immunoreactive proteins; in HeLa cells, phenylarsine oxide (PAO) decreases 110 +80 kDa immunoreactive proteins; in Jurkat cells, phenylarsine oxide (PAO) decreases 110 + 75 kDa immunoreactive proteins.

Scientific Background: IKKa (IKBKA, CHUK)) is a protein-serine/threonine kinase of the Other group and IKK family. It is involved in NF-kappa-B pathway, which activates multiple stress stimuli including inflammatory cytokines, infection, and DNA damage. The activity of the kinase enables for NF-kappa-B to enter the nucleus and stimulate the transcription of genes involved in the immune response, control of cell growth, and cellular protection against apoptosis. It is Inhibited by phosphorylation at S733, S740, and S750.
