Validation Data Gallery

• 

  WB analysis of NIH/3T3 using 66221-1-Ig (same clone as 66221-1-PBS)

  NIH/3T3 cells were subjected to SDS PAGE followed by western blot with 66221-1-Ig (Alpha E catenin antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66221-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human stomach using 66221-1-Ig (same clone as 66221-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human stomach tissue slide using 66221-1-Ig (Alpha E catenin antibody at dilution of 1:200 (under 10x lens). This data was developed using the same antibody clone with 66221-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human stomach using 66221-1-Ig (same clone as 66221-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human stomach tissue slide using 66221-1-Ig (Alpha E catenin antibody at dilution of 1:200 (under 40x lens). This data was developed using the same antibody clone with 66221-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human colon using 66221-1-Ig (same clone as 66221-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human colon tissue slide using 66221-1-Ig (Alpha E catenin antibody at dilution of 1:200 (under 10x lens). This data was developed using the same antibody clone with 66221-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human colon using 66221-1-Ig (same clone as 66221-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human colon tissue slide using 66221-1-Ig (Alpha E catenin antibody at dilution of 1:200 (under 40x lens). This data was developed using the same antibody clone with 66221-1-PBS in a different storage buffer formulation.

• 

  FC experiment of MCF-7 using 66221-1-Ig (same clone as 66221-1-PBS)

  1X10^6 MCF-7 cells were intracellularly stained with 0.4 ug Anti-Human Alpha E-Catenin (66221-1-Ig, Clone:2B7B8) and CoraLite®488-Conjugated AffiniPure Goat Anti-Mouse IgG(H+L) at dilution 1:1000 (red), or 0.4 ug Mouse IgG1 Isotype Control (MOPC-21) (65124-1-Ig, Clone: MOPC-21) (blue). Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C). This data was developed using the same antibody clone with 66221-1-PBS in a different storage buffer formulation.

Background Information

Alpha catenin is an essential component of adherens junctions that connects E-cadherin-β-catenin complexes with the actin cytoskeleton. It also recruits a range of other important proteins to developing intercellular junctions. Three alpha catenins exist in human: alpha-E-catenin, alpha-N-catenin, and alpha-T-catenin, which share substantial amino-acid sequence similarity but have distinct tissue distribution. alpha-E-catenin is ubiquitously expressed, alpha-N-catenin is restricted to neuronal tissue, and alpha-T-catenin is primarily expressed in heart tissue. Reduced levels of alpha-E-catenin protein seem to be characteristic of many different human cancers, including malignant tumours of the breast, colon, stomach, oesophagus, bladder and liver. In addition, the loss of alpha-E-catenin often correlates with the degree of tumour differentiation and metastasis.
