Scientific Data

Western Blot Detection of Human Fibroblast Activation Protein a/FAP antibody by Western Blot. View Larger

Detection of Human Fibroblast Activation Protein alpha /FAP by Western Blot. Western blot shows lysates of WI-38 human lung fibroblast cell line. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human Fibroblast Activation Protein a/FAP Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF3715) followed by Streptavidin-HRP (Catalog # DY998). A specific band was detected for Fibroblast Activation Protein a/FAP at approximately 97 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Fibroblast Activation Protein alpha/FAP

FAP (also known as seprase) is a Type II transmembrane serine protease that is structurally related to dipeptidyl peptidase IV (1). FAP has substrate specificity similar to dipeptidyl peptidase IV, which is specific for N-terminal Xaa-Pro sequences, but FAP is also an endopeptidase able to degrade gelatin and Type I collagen (2). The enzymatically active form of FAP is a dimer (3). FAP has a restricted tissue distribution. It is not detectable in normal tissues or resting fibroblasts, but is highly expressed on reactive stromal fibroblasts in epithelial cancers (4), in granulation tissue during wound healing, and in bone and soft tissue sarcomas (5). Because of its expression patterns and enzymatic activities, FAP is believed to play roles in tumor invasion, tissue remodeling, and wound repair.

Human Fibroblast Activation Protein  alpha /FAP Biotinylated Antibody
By Marco Carretta on 11/10/2017
Application: Flow Sample Tested: Tumor cell lyastes Species: Mouse

Since the mouse FAP shares ~90% of the human protein sequence, in our hands this antibody works good also mouse cells.
We are using it for flow cytometry on primary mouse cells in combination with APC Streptavidin (Biolegend, 405207). The staining works properly with a concentration of 1:20 of FAP Biotinylated Antibody and 1:100 of APC Streptavidin.
