Whole cell extracts (15 µg total protein) from the indicated cell lines were resolved on a 4-12% Bis-Tris gel, transferred to a PVDF membrane, and probed with 0.5 µg/mL of purified anti-FAP (clone A21107A) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP Goat anti-rat IgG (Cat. No. 405405) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:10000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

    IHC staining of purified anti-FAP (clone A21107A) on formalin-fixed paraffin-embedded human bladder tissue. Following antigen retrieval using Sodium Citrate H.I.E.R., 1x (Cat. No. 928502), the tissue was incubated with 5 µg/mL of primary antibody followed by incubation with Alexa Fluor® 647 Goat anti-rat IgG (Cat. No. 405416) (panels A and B) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801) (panel A). Images were captured with a 40X objective. Scale bar: 50 µm

Description

Fibroblast activation protein (FAP) is a cell surface and soluble protein with diverse functions in tissue homeostasis and diseases. As a prolyl peptidase, FAP cleaves peptide bonds following a proline residue. Primarily expressed by activated fibroblasts, FAP plays a crucial role in tissue remodeling and repair. Capable of being shed into the cellular milieu, FAP is involved in the breakdown and modification of the extracellular matrix, which is essential for tissue regeneration during wound healing and tissue repair. Moreover, FAP has been found to be overexpressed in the tumor microenvironment, where it potentially promotes tumor growth, invasion, and metastasis. This association with cancer has led to investigations exploring FAP as a potential therapeutic target for cancer treatment. FAP is inactive when monomeric and must form a homodimer to become functional for both the cell surface and soluble forms.
