General description

Fibroblast activation protein alpha (FAP), also known as Seprase, is a 97 kDa, type II cell surface glycoprotein belonging to the serine protease family. Although FAP is considered fibroblast specific, it is not found in normal healthy fibroblasts. FAP is most commonly found in stromal, tumor fibroblasts, and is likely involved in ECM pericellular proteolysis, endothelial cell migration and invasion into the ECM. The presence of FAP in human epithelial carcinoma is increased, particularly in breast, colorectal, lung, and ovarian carcinomas. FAP is also transiently observed in developing cells, or in tissues that are undergoing wound healing or suffering from chronic inflammatory conditions. Due to its specific distribution both to tumor fibroblasts and to inflammed tissue, FAP makes a promising target for research in tumor-stromal studies and in therapeutic studies.

Specificity

The antibody recognizes the extracellular domain of Fibroblast activation protein alpha

Immunogen

Epitope: Extracellular domain
Histidine-tagged recombinant protein corresponding to human FAP.

Application

Detect Fibroblast activation protein alpha (FAP) using this Anti-Fibroblast activation protein alpha (FAP) Antibody validated for use in WB, IH.
Immunohistochemistry: A 1:750 dilution of a previous lot of FAP antibody was used to immunohistochemically stain frozen tissue sections of HEK-FAP or HT-29 xenograft tumors from C.B17 mice (Cheng, 2002).

Inhibition: Inhibition of dipeptidyl peptidase activity with a previous lot of FAP antibody on HT-29 xenograft tumors was demonstrated by an independent laboratory (Cheng, 2002).

Val-boroPro (Talabostat, PT-100), a nonselective inhibitor of post-proline cleaving serine proteases, stimulates mammalian immune systems through an unknown mechanism of action. Despite this lack of mechanistic understanding, Val-boroPro has attracted substantial interest as a potential anticancer agent, reaching phase 3

KRAS mutant pancreatic ductal adenocarcinoma (PDAC) is characterized by a desmoplastic response that promotes hypovascularity, immunosuppression, and resistance to chemo- and immunotherapies. We show that a combination of MEK and CDK4/6 inhibitors that target KRAS-directed oncogenic signaling can suppress PDAC

Biomechanical changes in the tumor microenvironment influence tumor progression and metastases. Collagen content and fiber organization within the tumor stroma are major contributors to biomechanical changes (e., tumor stiffness) and correlated with tumor aggressiveness and outcome.
