Technical Data
C2069-39F
Catenin, p120, phosphorylated (Tyr291)
Description:
Catenins are proteins that are linked to the cytoplasmic domain of transmembrane cadherins. p120 Catenin is one member of this Armadillo gene family of junctional plaque proteins (1-3). The association of catenins to cadherins produces a complex which is linked to the actin filament network, and which seems to be important for cadherins cell-adhesion properties. Recently it became clear that some catenins also mediate nuclear signaling (1). p120 Catenin is implicated both in cell transformation by SRC and in ligand-induced receptor signaling through the EGF, PDGF, CSF-1 and ERBB2 receptors.

Applications:
Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:10,000-1:20,000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Manufactured incorporating RabMAb® technology under Epitomics US patents, No 5,675,063 and 7,429,487, owned by Abcam.
