Empty Tetramers

Faster, brighter, more flexible and down to €/$17 per antigen specificity using Empty MHC tetramers.


Our Empty Loadable Tetramer solution is an easy, fast, cost-effective product.


Our Empty Loadable Tetramers are not dependent on a peptide exchange factor and exchange of peptide or UV cleavage and exchange of UV-labile peptides.


Our Empty Tetramers are truly empty and ready to accept a peptide antigen – just add peptide and stain within minutes.


Our technology was recently published in Science Immunology.

What can Empty Loadable Tetramers be used for?

Empty Loadable Tetramers can be used just like conventional MHC Tetramers. However, they are supplied empty of peptide antigen and you have to add peptide before you can stain your T cells.


What is the advantage of Empty loadable Tetramers?

Besides the improved stability and brighter staining the major advantage is that you can instantly DIY your own Tetramer specificities just by adding a specific peptide antigen (See protocol). This is a dramatic increase in flexibility and can decrease your Tetramer expenses significantly.


The flexibility of Empty Loadable Tetramers make these reagents ideal for multi-color flow cytometry or combinatorial encoding and detection of multiple T cell specificities in a single sample. This is in particular advantageous when you are staining for multiple T cell specificities for neoantigens or proprietary peptide antigens.


MHC Tetramers for immunotherapeutic development.

Immunotherapy and vaccine development is largely dependent on tetramer technologies for epitope detection, monitoring of disease and progression of disease, monitoring of immunotherapeutic effect on disease-specific T cells and the aforementioned isolation, expansion and re-introduction of disease specific T cells into the patient.

Advantages of Tetramer assays

Tetramer assays allow physical isolation of the cells by fluorescence-activated cell sorter (FACS) and subsequent further study of sorted cells. As a flow-cytometry-based application, tetramers are also easy to use and have a short assay time. Tetramers also allow the antigen specific immune response to be analyzed in both animal models and in human.
