PE-H-2Kb/OVA (SIINFEKL) MHC Tetramer

CAT#: MHC-LC649

This product is a tetramer of biotinylated peptide/MHC complex with streptavidin mainly composed of OVA-derived peptide of SIINFEKL sequence covering 257-264 and H-2Kb molecule. The pMHC tetramer recognizes mouse CD8 T cells, and can be used in the analysis of individual antigen-specific T cells.

Target

  • Antigen Introduction
  • Ovalbumin (abbreviated OVA) is the main protein found in egg white, making up approximately 55% of the total protein. Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine protease inhibitor. The function of ovalbumin is unknown, although it is presumed to be a storage protein.
  • Alternative Names
  • OVA; Ovalbumin

    This study explores the use of a novel IL-2 mutant retargeted to NKG2D for the adoptive transfer of tumor-infiltrating leukocytes (TILs) in a murine model of malignant melanoma. Traditional IL-2 protocols for TIL expansion support the growth of both cytotoxic and regulatory T cells, leading to inconsistent therapeutic outcomes. The research demonstrates that the novel NKG2D-retargeted IL-2 (OMCPmutIL-2) preferentially expands cytotoxic T cells, including CD8+ T cells, NK cells, and γδ T cells, enhancing their tumor-homing abilities and providing superior tumor control compared to wild-type IL-2-expanded TILs.
    Creative Biolabs significantly contributed to this research by providing the H-2kb/OVA (SINFEKL) MHC Tetramer (Cat#: MHC-LC649). This product was essential for the detailed flow cytometric analysis and characterization of the TILs. The tetramer allowed for the precise identification and sorting of OVA-specific CD8+ T cells within the tumor microenvironment, facilitating the study of their expansion and function under the influence of the novel OMCPmutIL-2 cytokine. This contribution was crucial for demonstrating the superior tumor control achieved with the retargeted IL-2 therapy.
