ICC shows positive staining in MCF7 cells. Anti-E-Cadherin (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. The cells were fixed with 100% ice-cold methanol and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).

Background
E-cadherin is a transmembrane glycoprotein which connects epithelial cells together at adherens junctions. In normal cells, E-cadherin exerts its tumour suppressing role mainly by sequestering β-catenin from its binding to LEF (Lymphoid enhancer factor)/TCF (T cell factor) which serves the function of transcribing genes of the proliferative Wnt signaling pathway. Despite the ongoing debate on whether the loss of E-cadherin is the cause or effect of epithelial-mesenchymal transition (EMT), E-cadherin functional loss has frequently been associated with poor prognosis and survival in patients of various cancers. The dysregulation of E-cadherin expression that leads to carcinogenesis happens mostly at the epigenetic level but there are cases of genetic alterations as well. E-cadherin expression has been linked to the cellular functions of invasiveness reduction, growth inhibition, apoptosis, cell cycle arrest and differentiation.

Immunocytochemistry
Negative control: ICC shows negative staining in MDA-MB-231 cells. Anti-E-Cadherin (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution and incubated overnight at 4°C. The cells were fixed with 100% ice-cold methanol and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
Immunofluorescence
IF shows positive staining in paraffin-embedded human colon cancer. Anti-E-Cadherin (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
IF shows positive staining in paraffin-embedded mouse stomach. Anti-E-Cadherin (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
IF shows positive staining in paraffin-embedded rat stomach. Anti-E-Cadherin (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
