Beta-Catenin Antibody Cervical Carcinoma IHC. Immunohistochemistry of human cervical carcinoma using Beta-Catenin Antibody (clone CTNNB1/2030R) demonstrates strong membranous and cytoplasmic staining in tumor epithelial cells, consistent with CTNNB1 / Catenin beta-1 expression in adherens junctions, with focal areas suggesting increased cytoplasmic accumulation. Nuclear counterstain highlights tissue architecture, and stromal regions show comparatively minimal signal. This staining pattern reflects the dual role of beta-catenin in cell adhesion and Wnt signaling-associated redistribution. HIER: boil FFPE tissue sections in 10 mM citrate buffer, pH 6, for 10-20 min followed by cooling at RT for 20 min.
Beta-Catenin Antibody Tonsil IHC. Immunohistochemistry of human tonsil tissue using Beta-Catenin Antibody (clone CTNNB1/2030R) shows distinct membranous staining outlining epithelial cell borders within crypt regions, consistent with CTNNB1 / Catenin beta-1 localization at adherens junctions, with mild cytoplasmic signal in select epithelial cells. Lymphoid compartments display minimal staining, highlighting tissue-specific expression patterns. Hematoxylin counterstain provides nuclear contrast for structural context. HIER: boil FFPE tissue sections in 10 mM citrate buffer, pH 6, for 10-20 min followed by cooling at RT for 20 min.
Beta-Catenin Antibody HeLa Cell IF. Immunofluorescence analysis of PFA-fixed human HeLa cells using Beta-Catenin Antibody (clone CTNNB1/2030R) shows prominent membranous and cytoplasmic green fluorescence consistent with CTNNB1 / Catenin beta-1 localization at cell-cell junctions, outlining cell borders with additional intracellular signal. Reddot nuclear stain (red) clearly marks nuclei, providing contrast to the peripheral beta-catenin distribution. The observed pattern reflects the role of beta-catenin in adherens junction organization and cytoplasmic signaling pools.
Beta-Catenin Antibody HeLa Cell FACS. Flow cytometry analysis of PFA-fixed human HeLa cells using Beta-Catenin Antibody (clone CTNNB1/2030R) shows a clear rightward shift of the blue population relative to the red isotype control, indicating specific detection of CTNNB1 / Catenin beta-1 expression. The signal distribution supports intracellular localization consistent with beta-catenin’s cytoplasmic and membrane-associated pools following fixation and permeabilization. Red represents isotype control and blue represents recombinant beta-catenin antibody staining.
Beta-Catenin Antibody HeLa WB. Western blot analysis of human HeLa cell lysate using Beta-Catenin Antibody (clone CTNNB1/2030R) detects a prominent band at approximately 90-95 kDa, consistent with the predicted molecular weight of Catenin beta-1 / CTNNB1 at ~85 kDa with a modest upward shift commonly observed in SDS-PAGE. This migration difference is consistent with known phosphorylation of beta-catenin, which can alter electrophoretic mobility. The single dominant band supports specific detection of CTNNB1 in HeLa cells.
Beta-Catenin Antibody HuProt Microarray Specificity. Protein microarray analysis using Beta-Catenin Antibody (clone CTNNB1/2030R) demonstrates highly specific binding to CTNNB1 / Catenin beta-1, with the target protein ranked as the top hit and showing a strong Z score relative to all other proteins on the array. Signal intensity drops sharply for non-target proteins, supporting selective recognition with minimal off-target interaction. Z score represents the strength of signal in standard deviations above the mean of all array signals, while S score reflects the separation between the top-ranked target and the next highest signal, indicating relative specificity.
SDS-PAGE analysis of purified, BSA-free recombinant b-Catenin antibody (clone CTNNB1/2030R) as confirmation of integrity and purity.
Beta-Catenin Antibody Brain WB. Western blot analysis of human brain tissue lysate using Beta-Catenin Antibody (clone CTNNB1/2030R) detects a clear band at approximately 90-95 kDa, consistent with the predicted molecular weight of Catenin beta-1 / CTNNB1 at ~85 kDa with a commonly observed upward shift during SDS-PAGE. This shift is consistent with known phosphorylation of beta-catenin, which can affect electrophoretic mobility. The band pattern aligns with expected expression of CTNNB1 in neural tissue.

Description

Beta-catenin (CTNNB1) is a multifunctional protein that plays central roles in both cell adhesion and transcriptional regulation, functioning as a key effector of the Wnt signaling pathway and a structural component of cadherin-based adherens junctions. The Beta-Catenin Antibody / CTNNB1 Antibody is widely used to detect this dual-function protein across diverse biological systems, where it exhibits dynamic localization between the cytoplasm, nucleus, and cell membrane. CTNNB1 is encoded on chromosome 3p22.1 and belongs to the armadillo repeat protein family, characterized by multiple armadillo domains that mediate protein-protein interactions with cadherins, transcription factors, and regulatory complexes.

Beta-Catenin antibody, also referred to as CTNNB1 antibody and Catenin beta-1 antibody in the literature, recognizes a protein that integrates signaling and structural functions. At the plasma membrane, beta-catenin binds to E-cadherin and other classical cadherins, stabilizing cell-cell adhesion and maintaining epithelial tissue architecture. In this context, it anchors cadherin complexes to the actin cytoskeleton through interactions with alpha-catenin. Loss or redistribution of membranous beta-catenin is frequently associated with epithelial-to-mesenchymal transition and tumor progression, making CTNNB1 antibody detection valuable for studying changes in tissue organization.

In the cytoplasm, beta-catenin levels are tightly regulated by the destruction complex, which includes APC, AXIN, GSK3beta, and CK1. In the absence of Wnt signaling, beta-catenin undergoes phosphorylation-dependent degradation, maintaining low cytoplasmic levels. Upon Wnt pathway activation, this degradation is inhibited, leading to cytoplasmic accumulation and subsequent nuclear translocation. Within the nucleus, beta-catenin interacts with TCF/LEF transcription factors to regulate gene expression programs involved in proliferation, differentiation, and stem cell maintenance. This regulated shuttling between compartments highlights the importance of detecting CTNNB1 across multiple cellular contexts.

The recombinant rabbit monoclonal CTNNB1/2030R antibody is designed to detect beta-catenin expression with high specificity and consistency, supported by protein microarray specificity validation data that demonstrates selective binding to the intended target. This Beta-Catenin Antibody / CTNNB1 Antibody is suitable for detecting beta-catenin expression in a wide range of research applications where both structural and signaling roles are relevant. Its performance supports evaluation of subcellular localization patterns, including membranous staining in epithelial tissues and cytoplasmic or nuclear accumulation in signaling-active states.

Alterations in CTNNB1 are implicated in numerous cancers, including colorectal carcinoma, hepatocellular carcinoma, endometrial cancer, and melanoma. Mutations that stabilize beta-catenin or disrupt its regulation result in constitutive activation of Wnt signaling, contributing to oncogenesis. As a result, beta-catenin antibody detection is frequently used to assess pathway activation, tumor differentiation status, and disease progression. The ability to distinguish membranous versus nuclear localization further enhances its utility in cancer research and diagnostic pathology contexts. This antibody targets beta-catenin for research applications requiring reliable detection of CTNNB1 across adhesion and signaling states.
