This antibody specifically recognizes β-catenin phosphorylated at tyrosine 654 at 90 kDa and gamma-catenin at 70 kDa. Due to sequence homologies of the phospho-epitope surrounding pY 654 there may be crossreactions with other proteins (e.g. Annexin A11 at 56 kDa, gamma-catenin at 70 kDa, Desmoplakin at 81 kDa, TNFalpha-induced protein 2 at 73 kDa, Ribosomal protein S6 kinase alpha 6 at 90 kDa).
Western Blot. Recommended blocking buffer: Casein/Tween 20 based blocking and blot incubationbuffer. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
Restrictions
For Research Use only
Concentration
0.5 mg/mL
Buffer
PBS/0.09 % Na-Azide/PEG and Sucrose
Preservative
Sodium azide
Precaution of Use
WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Storage
4 °C/-80 °C
Storage Comment
Store the antibody (aliquote in liquid nitrogen) at -80 °C. Avoid repeated freezing and thawing. Thaw aliquots at 37 °C. Thawed aliquots may be stored at 4 °C up to 3 months. Shelf life: one year from despatch.
The α-, β- and γ-catenins are cytoplasmic proteins mediating the interaction of Ca2+-dependent transmembrane adhesion molecules (cadherins) with the cytoskeletal network. Additionally, β-catenin is a substrate of both receptor and non-receptor tyrosine kinases. Tyrosine 86 and tyrosine 654 are substrates of EGF receptor and src family kinases while tyrosine 142 is a substrate of fer tyrosine kinases.Synonyms: Beta-catenin, CTNNB, CTNNB1
