This product is a tetramer of biotinylated peptide/MHC complex with streptavidin mainly composed of HPV16-derived peptide of RAHYNIVTF sequence covering 49-57 and H-2Db molecule. The pMHC tetramer recognizes mouse CD8 T cells, and can be used in the analysis of individual antigen-specific T cells.

The study investigates the efficacy of the recombinant gorilla adenovirus HPV therapeutic vaccine, PRGN-2009, targeting HPV-associated malignancies. PRGN-2009 is designed to express multiple cytotoxic T cell epitopes from the HPV 16/18 E6 and E7 proteins, aiming to stimulate strong HPV-specific immune responses. The vaccine was tested in both humanized and syngeneic mouse models bearing HPV16+ tumors. Results showed significant tumor volume reduction and increased infiltration of multifunctional CD8+ and CD4+ T cells in the tumor microenvironment. These findings suggest PRGN-2009's potential as an effective therapeutic vaccine for HPV-associated cancers.
Creative Biolabs provided crucial reagents for this study, including the mouse HPV16 E7 tetramer (CAT#: MHC-LC291). This tetramer was essential for evaluating antigen-specific CD8+ T cell responses in the tumor microenvironment. By facilitating the detailed assessment of immune cell infiltration and functionality, Creative Biolabs' products enabled a comprehensive analysis of PRGN-2009's immunogenicity and antitumor efficacy.
