Product Details

The VK8 monoclonal antibody reacts with human MUC16 also known as CA125. MUC16 is a large transmembrane glycoprotein primarily expressed on the surface of epithelial cells in various tissues. MUC16 is known for its clinical significance as a tumor marker for ovarian cancer. MUC16 has also been shown to play a role in cell adhesion, immune regulation, and protection of the ocular surface. Due to its complex structure and diverse functions, MUC16 is an area of ongoing research in both cancer biology and immunology.

MUC16, the mucin that contains the CA125 epitopes, suppresses the cytolytic responses of human NK cells and inhibits the efficacy of therapeutic antibodies. Here, we provide further evidence of the regulatory role of MUC16 on human and murine NK cells and macrophages.

"Mesothelin-MUC16 binding is a high affinity, N-glycan dependent interaction that facilitates peritoneal metastasis of ovarian tumors" Mol Cancer 5(1):50. PubMed

The mucin MUC16 and the glycosylphosphatidylinositol anchored glycoprotein mesothelin likely facilitate the peritoneal metastasis of ovarian tumors. The biochemical basis and the kinetics of the binding between these two glycoproteins are not clearly understood. Here we have addressed this deficit and provide further evidence supporting the role of the MUC16-mesothelin interaction in facilitating cell-cell binding under conditions that mimic the peritoneal environment.
