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

CAT#: MHC-LC653

This product is a tetramer of biotinylated peptide/MHC complex with streptavidin mainly composed of OVA-derived peptide of SIIGFEKL 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

Breast cancer biomarkers at key points during disease progression
Great for Immunology Studies
I have been using the PE-H-2Kb/OVA MHC Tetramer for some time, and it's been invaluable in my immune response studies. Its specificity and high fluorescence allow detailed analysis of CD8+ T cell populations, which is crucial for my research on immune therapies.
Breast cancer biomarkers at key points during disease progression
Highly Effective for T Cell Analysis
We employed this tetramer in our lab's studies on T cell responses to cancer. It worked seamlessly with our flow cytometry setup, providing clear, distinct results. The PE fluorescence was notably strong, making it easier to differentiate specific T cell populations.
Breast cancer biomarkers at key points during disease progression
Enhanced Flow Cytometry Experience
Transitioning to using this tetramer improved our flow cytometry results substantially. The added sensitivity and specificity for CD8+ T cell recognition have been apparent in the clarity of our data outputs, even in complex samples.

Q&As

  1. What is the primary application of the PE-H-2Kb/OVA MHC Tetramer?

    A: The PE-H-2Kb/OVA MHC Tetramer is primarily used in flow cytometry to analyze antigen-specific CD8+ T cells in mouse models. Researchers utilize this tool to measure immune responses, particularly in studies involving ovalbumin as a model antigen.

  2. What are the typical research areas where this tetramer is used?

    A: The PE-H-2Kb/OVA MHC Tetramer is often used in immunology studies, including cancer research, vaccine development, and autoimmune disease exploration, among others. Its applications are broad, given its role in tracking T cell responses.

  3. What controls should I consider using with this tetramer in assays?

    A: Appropriate controls include staining with a non-specific tetramer or using cells known to lack the T cell receptor specificity for SIIGFEKL. Isotype controls and unstained cells are also recommended for accurate analysis.
