Product Details

  • Synonym

    GUCY2C, GUC2C, STAR, STA receptor, hSTAR, GC-C

  • Source

    APC-Labeled Human GUCY2C Protein, His Tag (GUC-HA2H7) is produced via conjugation of APC to Human GUCY2C Protein, His Tag with a new generation site-specific technology under Star Staining labeling platform. Human GUCY2C Protein, His Tag is expressed from human 293 cells (HEK293). It contains AA Ser 24 - Gln 430 (Accession # P25092-1).

    Predicted N-terminus: Ser 24

    FACS Analysis of Anti-GUCY2C CAR Expression

     GUCY2C CAR_T

    5e5 of anti-GUCY2C CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of APC-Labeled Human GUCY2C Protein, His Tag (Cat. No. GUC-HA2H7) and negative control protein respectively (Fig. C and B), and non-transfected 293 cells were used as a control (Fig. A). APC signal was used to evaluate the binding activity (QC tested).

  • FACS Analysis of Non-specific binding to PBMCs

     GUCY2C CAR_T

    5e5 of PBMCs were stained with APC-Labeled Human GUCY2C Protein, His Tag (Cat. No. GUC-HA2H7) and anti-CD3 antibody, washed and then analyzed with FACS. FITC signal was used to evaluate the expression of CD3+ T cells in PBMCs, and APC signal was used to evaluate the non-specific binding activity to PBMCs (QC tested).

Background

GUCY2C (Guanylyl Cyclase C), also known as heat-stable enterotoxin receptor, is a type I transmembrane protein of the guanylate cyclase (gc) family that signal by producing cGMP. Guanylate cyclase C (GUCY2C) and its hormones guanylin and uroguanylin have recently emerged as one paracrine axis defending intestinal mucosal integrity against mutational, chemical, and inflammatory injury. GUCY2C murine CAR-T cells recognized and killed human colorectal cancer cells endogenously expressing GUCY2C. Thus, we have identified a human GUCY2C-specific CAR-T cell therapy approach that may be developed for the treatment of GUCY2C-expressing metastatic colorectal cancer.
