Product Specific Information

Description: The 15B8 monoclonal antibody reacts with human and mouse beta-catenin, one member of a family of catenins, which are intracellular proteins that interact with cadherins to mediate cellular adhesion. More specifically, beta-catenin binds to the cytoplasmic tail of E-cadherin. In addition, this molecule is a component of the canonical Wnt signaling pathway. In the absence of Wnt binding its receptor, beta-catenin is phosphorylated and resides in the cytoplasm where it is eventually targeted for degradation by ubiquitination. Upon Wnt binding, beta-catenin becomes dephosphorylated, translocates to the nucleus, and modulates gene expression in partnership with the transcription factors T cell factor (TCF) and lymphocyte enhancer binding factor (LEF). Expression of beta-catenin is found in a wide variety of non-immune and immune tissues, including thymocytes and T and B lymphocytes. The Wnt and beta-catenin signaling pathway has been demonstrated to play a crucial role in the development of T, B, and hematopoietic stem cells.

Applications Reported: This 15B8 antibody has been reported for use in intracellular staining followed by flow cytometric analysis.

Applications Tested: This 15B8 antibody has been pre-titrated and tested by intracellular staining and flow cytometric analysis of Jurkat cell line using the Foxp3/Transcription Factor Staining Buffer Set (Product # 00-5523-00). This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

Excitation: 488 nm; Emission: 519 nm; Laser: Blue Laser.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

Beta-catenin, an adherens junction (AJ) protein, was originally identified as a component of cell-cell adhesion structures. AJs are necessary for the creation and maintenance of epithelial cell layers by regulating cell growth and adhesion between cells. Beta-catenin interacts with the cytoplasmic domain of E-cadherin and links E-cadherin to alpha-catenin, which in turn mediates anchorage of the E-cadherin complex to the cortical actin cytoskeleton. Studies show that Beta-catenin also binds to another cytoskeletal complex containing the adenomatous polyposis coli protein and microtubules, and interacts with several signaling pathways that include tyrosine kinases, phosphatases and Wnt/Wingless. The interplay between beta-catenin, cytoskeletal complexes and signaling pathways may regulate morphogenesis. Beta-catenin is expressed in several hair follicle cell types, basal and peripheral matrix cells, and cells of the outer and inner root sheats. A pathological role of beta-catenin has been identified in pilomatrixoma (PTR), medulloblastoma (MDB), colorectal cancer (CRC), ovarian cancer, and tumor development. In the nucleus, beta-catenin serves to co activate a family of Lef/Tcf transcription factors that stimulate transcription of target genes including those encoding cyclin D and c-myc that promote cell proliferation. The influence on cell proliferation is the molecular basis for the role of beta-catenin in tumorgenesis, specifically, solid tumors of the breast, colon, liver, lung, gastric, prostate, and skin.
