2e5 of transient transfected anti- GUCY2C ScFv CAR-293 cells were stained with 0.01ug Alexa Fluor 647-Labeled GUCY2C Fc Chimera Protein, Human, (Cat. No. UA011282) and unlable respectively (Fig. C and B), and non-transfected 293 cells were used as a control (Fig. A). Alexa Fluor 647 signal was used to evaluate the binding activity.
2e5 of transient transfected anti- GUCY2C ScFv CAR-293 cells were stained with isotype and Whitlow/218 Linker-Alexa Fluor® 488 (Fig. D and E). Alexa Fluor® 488 signal was used to evaluate the binding activity.

Background
Guanylyl Cyclase C (GUCY2C), also known as heat-stable enterotoxin receptor, is a type I transmembrane protein of the guanylate cyclase (GC) family expressed by intestinal epithelial cells from the duodenum to rectum. Mature human GUCY2C consists of an extracellular domain (ECD) with a ligand binding domain, a transmembrane segment and a cytoplasmic region possessing a kinase and GC catalytic domain. Endogenous ligands of GUCY2C include guanylin and uroguanylin. GUCY2C in epithelial cells plays an important role in cell dynamics and homeostatic balance of proliferation, metabolism, and differentiation that organizes the guanylyl cyclase C hormone axis. GUCY2C is also expressed in the brain and is implicated in attention deficiency and hyperactive behavior. The activation of cyclic guanosine monophosphate (cGMP), a second intracellular messenger, can stimulate the production of cyclic guanosine monophosphate (CGMP), which plays a role in regulating homeostasis, maintaining intestinal barrier function, and exerting anti-inflammatory activity.
