Technical Data
Catenin, beta
The catenins (a, b and g) are ubiquitously expressed, cytoplasmic proteins associated with E-cadherin at cellular junctions. b-catenin also binds to N-cadherin and coimmunoprecipitates with APC. Cadherin/catenin complexes are linked to the cytoskeleton via a direct association between a-actinin and a-catenin. Increased tyrosine phosphorylation can disrupt catenin-cadherin complexes, influencing cellular adhesion.

Suitable for use in Immunoprecipitation, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunoprecipitation (Native verified): 10ug/mg Use Protein A.
Western Blot: 5-10ug/ml for 2 hours at RT
Immunohistochemistry (Formalin/paraffin): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 minutes followed by cooling at RT for 20 minutes.
Optimal dilutions to be determined by the researcher.

Positive Control:
MCF-7 cells. Breast carcinoma.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. 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.
