CQY684
Based on 1 Customer Validation
CQY684 (PCA062 antibody) is a monoclonal antibody targeting CDH3/P-cadherin, which locks P-cadherin in an X-dimer conformation and enhances the stability of this adhesion structure. CQY684 induces P-cadherin phosphorylation and promotes its dissociation from the cytoplasmic region of P-cadherin. As an endocytosis inducer and lysosome-targeting agent, CQY684 facilitates the internalization of the P-cadherin-CQY684 complex and improves the turnover efficiency of P-cadherin. CQY684 serves as a platform for the delivery of intracellular anticancer compounds, which is achieved through the targeted lysosomal transport of the antibody-P-cadherin complex. CQY684 is applicable to the research of breast cancer, esophageal cancer, and head and neck cancer.

Biological Activity
Human IgG1 kappa
Human
CDH3/P-cadherin
CQY684 (200 nM; overnight) impairs Pcad-mediated intercellular adhesion and aggregation in A431 cells expressing wild-type Pcad[1].
CQY684 (administered when cells reach 70% confluence at 200 nM) promotes the endocytosis of Pcad and its trafficking to lysosomes in A431 cells expressing wild-type Pcad, and reduces the level of Pcad on the cell surface[1].
CQY684 (administered during cell culture) induces phosphorylation of p120 catenin in A431 cells expressing wild-type Pcad, and promotes the dissociation of p120-catenin from Pcad[1].
CQY684 (200 nM; 24+ h) increases the dynamics of Pcad-containing intercellular junctions in A431 cells expressing wild-type Pcad[1].

Cell Line:A431 E-cadherin/Pcad double knockout cells rescued with full-length WT Pcad-mCherry
-
Concentration:200 nM
-
Incubation Time:During cell growth to 70% confluence
-
Result:Increased internalization of Pcad, resulting in significantly higher colocalization with LAMP1 (Pearson's coefficient elevated compared to no-antibody conditions).

-
Concentration:200 nM
-
Incubation Time:During cell growth to confluence
-
Result:Reduced the amount of cell surface Pcad compared to no-antibody conditions, though the ratio of surface to total Pcad remained similar across conditions.
