Detects human Fibroblast Activation Protein alpha/FAP in ELISAs and Western blots. In sandwich immunoassays, less than 0.2% cross-reactivity with recombinant human DPPIV is observed.FAP (fibroblast activation protein-alpha; also known as seprase) is a type II transmembrane serine protease that degrades gelatin, Type I collagen, and N-terminal prolines. FAP is induced on reactive stromal fibroblasts in epithelial cancers, sarcomas, and granulation tissue, and may play roles in tumor invasion, tissue remodeling, and wound repair.Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
