Additional Information: This antibody is specific to beta-catenin phosphorylated at Tyr 489. Beta-1 Catenin is a Key downstream component of the canonical Wnt signaling pathway whose function is affected by differential phosphorylation. Specificity tested on Y489F beta-catenin. See mAb PY654-B-catenin (IgG) for an antibody specific to beta-catenin phosphorylated at Tyr 654. The catenin target of PY489-B-catenin has been described as nuclear-bound/active beta-catenin, and the target of PY654-B-catenin (IgG) has been described as membrane-bound/cytoplasmic beta-catenin.

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable.
To ensure retention of antibody activity, we recommend aliquotting the product into two parts:
1) a volume of antibody stored at 4°C to be used within two weeks.
2) the remaining product diluted with an equal volume of molecular grade glycerol and stored at -20°C.
While optimal Ig concentration for an application will vary, a good starting concentration for immunohistochemistry (IHC),
immunofluorescence(IF) and staining is 2-5 µg/ml.
For Western blots, the concentration is decreased by one order of magnitude (that is, 0.2-0.5 µg/ml).
All cell products contain the antimicrobial ProClin. See our FAQ section for additional information.
