- We purchased this protein to verify the affinity of antibodies during screening. Preliminary ELISA testing indicated that its affinity performance is remarkably stable, bolstering our confidence in subsequent experiments. Shortly thereafter, we conducted SPR testing, and the results were highly satisfactory. We anticipate that this protein will maintain its exceptional performance in future cell experiments, providing invaluable data support for our research.

背景（Background）
Nectin-4 (gene name PVRL4, poliovirus receptor-like 4) is a 66 kDa type I transmembrane glycoprotein belonging to the Nectin family of Ig superfamily proteins. Nectins are cell adhesion molecules that play a key role in various biological processes such as polarity, proliferation, differentiation and migration, for epithelial, endothelial, immune and neuronal cells, during development and adult life. Nectin-4 is a tumor-associated antigen in 50%, 49% and 86%o of breast, ovarian and lung carcinomas, respectively, mostly on tumors of bad prognosis. Its expression is not detected in the corresponding normal tissues.
