Background Information
Cadherins are a family of transmembrane glycoproteins that mediate calcium-dependent cell-cell adhesion and play an important role in the maintenance of normal tissue architecture. N-cadherin (neural cadherin), also known as CDH2 (cadherin 2), is a 130-kDa transmembrane protein and a classical member of the cadherin superfamily which also include E-, P-, R-, and B-cadherins. Expression of N-cadherin has been reported on various cell types including neurons, endothelial cells and cardiac myocytes (PMID: 11282032; 9508779; 8125202). N-cadherin has functions in early brain morphogenesis, synaptogenesis and synaptic plasticity (PMID: 23321619). The N-cadherin ectodomain can be cleaved, leading to the generation of a 90 kD N-terminal fragment (PMID: 16998833; 17028923).

Reviews
What customers say
Across three reviews, results are mixed. One user reported a clear 140 kD band by Western blot at 1:2000 dilution in U2OS cells. For immunofluorescence, one user noted acceptable staining in iPSC-derived cardiomyocytes at 1:400 but observed less distinct membrane localization compared to an alternative rabbit pan-cadherin antibody. Another user found no detectable signal in 3D cholangiocyte organoids at 1:100 and suggested trying different concentrations or an alternative antibody. Overall, the antibody performs well for WB but IF results vary by cell type and protocol.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Kiara (Verified Customer) (07-28-2025) | This primary antibody was not internally validated for IF, but there was a paper published that it worked on 4% PFA-fixed H9 ESCs, so I gave it a shot anyway. However, the staining did not show a nice membrane localization that our lab usually sees when using a different rabbit pan-cadherin primary antibody.
 |
Davide (Verified Customer) (06-13-2023) | The antibody didn't produce any signal in 3d primary human cholangiocyte organoids. I would recommend either to try other antibody concentration or to try another Ab. It was tried on a cell condition which was recently reported to stimulate the CDH2 protein expression. However it should also be present in control condition at low levels.

Udesh (Verified Customer) (10-13-2022) | Used the Ab at 1:2000 dilution in 5% NFDM and observed a band at 140 kD. Blocked in 5% NFDM for 1H at RT.
