CDH1 Antibody - E-cadherin Antibody for IHC, WB, IF

Introduction

Cadherin 1 (CDH1), also known as E-cadherin, is a calcium-dependent cell adhesion protein that plays a central role in epithelial tissue architecture and maintenance. CDH1 is localized to the cell membrane where it mediates homophilic cell-cell adhesion through adherens junctions, supporting tissue integrity and polarity. Loss or dysfunction of E-cadherin is strongly associated with epithelial-to-mesenchymal transition (EMT), tumor progression, and metastasis, making CDH1 antibody tools essential for cancer research and epithelial biology studies.

CDH1 antibody reagents are widely used to evaluate epithelial differentiation status, tumor classification, and changes in cell adhesion. E-cadherin expression is typically strong in normal epithelial tissues and reduced or absent in invasive carcinomas, particularly in diffuse gastric cancer and lobular breast carcinoma. This makes CDH1 antibody a critical marker in both diagnostic pathology and mechanistic studies of tumor progression.

CDH1 Antibody for Immunohistochemistry (IHC)

CDH1 antibody for IHC is one of the most widely used approaches for assessing epithelial cell adhesion and tumor differentiation in formalin-fixed, paraffin-embedded tissues. Immunohistochemical staining of E-cadherin typically shows strong membranous localization in epithelial cells, reflecting its role in adherens junctions.

In normal tissues, CDH1 antibody highlights organized epithelial layers with crisp cell membrane staining. In cancer tissues, loss, reduction, or cytoplasmic redistribution of staining can indicate disrupted adhesion and increased invasive potential. CDH1 IHC antibody staining is especially important in distinguishing ductal versus lobular breast carcinoma and in evaluating gastric cancer subtypes.

CDH1 Antibody for Western Blot (WB)

CDH1 antibody for western blot is used to detect E-cadherin protein expression levels and to study changes in protein stability, cleavage, or regulation. Western blot analysis typically identifies CDH1 as a band corresponding to the full-length membrane protein, with additional bands sometimes observed due to proteolytic processing or post-translational modification.

This application is particularly useful in EMT studies, where loss of E-cadherin expression is a hallmark event. CDH1 western blot antibody allows researchers to quantify protein downregulation and correlate it with transcriptional changes and signaling pathway activation

CDH1 Antibody for Immunofluorescence (IF)

CDH1 antibody for IF enables high-resolution visualization of E-cadherin localization within cells. Immunofluorescence staining typically reveals distinct membrane-associated signal outlining cell-cell contacts in epithelial monolayers.

This application is valuable for studying cell polarity, junction assembly, and dynamic changes in adhesion during processes such as migration or EMT. CDH1 IF antibody is frequently used in co-localization studies with cytoskeletal or junctional proteins to better understand epithelial organization.

CDH1 Antibody Applications and Research Utility

CDH1 antibody products support a wide range of experimental workflows focused on epithelial biology, cancer progression, and cell adhesion mechanisms. Because E-cadherin plays a central role in maintaining tissue structure, its detection provides insight into both normal physiology and disease states.

Researchers use CDH1 antibody reagents to:

• Assess epithelial differentiation and tissue organization
• Identify tumor subtypes and invasive potential
• Study epithelial-to-mesenchymal transition (EMT)
• Evaluate cell-cell adhesion and junctional integrity
• Monitor signaling pathways linked to adhesion loss

Key Targets and Related Proteins

CDH1 functions within a broader network of adhesion and signaling proteins. Related targets often studied alongside CDH1 antibody include:

• Beta-catenin (CTNNB1) - links E-cadherin to the actin cytoskeleton
• Alpha-catenin (CTNNA1) - stabilizes adherens junctions
• N-cadherin (CDH2) - associated with mesenchymal transition
• Vimentin (VIM) - marker of EMT and cytoskeletal remodeling

These markers are frequently used together to characterize epithelial versus mesenchymal phenotypes.

Conclusion

CDH1 antibody remains a cornerstone tool for studying epithelial biology and cancer progression. Whether used for immunohistochemistry, western blot, or immunofluorescence, E-cadherin detection provides critical insight into cell adhesion, tissue integrity, and disease mechanisms. Selecting the appropriate CDH1 antibody for each application ensures accurate and reproducible results across experimental systems.
