The MHC glycoprotein may be preloaded with a second agonist to optimize the assay. Alternatively, the method employs the displacement of a preloaded, labeled peptide from the MHC glycoprotein by the candidate of interest. The level of agonist in the complex may be determined by the effect of ...
PBMC from LTBI donors were incubated with 10 mg/ml peptides from ESAT-6, and the number of IFN-g-producing cells was enumerated in an ELISPOT assay. ESAT-6 has four antigenic regions, indicated by capped lines. The numbers of donors tested for each region were n = 7 for Regions 1 ...

The features of peptide antigens that contribute to their immunogenicity are not well understood. Although the stability of peptide-MHC (pMHC) is known to be important, current assays assess this interaction only for peptides in isolation and not in the
Firstly, peptides deemed as antigenic were processed to extract their binding sites. These correspond to positive epitopes from IEDB as classified by their qualitative labels “Positive High”, “Positive Intermediate” and “Positive Low” for each MHC class I haplotype in mice irrespective of the...

3. Dissecting immune T-cell responses using MHC-peptide tetramers The efficiency and specificity of MHC-peptide tetramers are now firmly established. BIAcore binding analysis of soluble MHC to TCRs has shown that MHC multimerization indeed compensates for the low affinity of this interaction: MHC...
A pharmaceutical composition comprises (a) a peptide of between 8 and 20 amino acids comprising at least 8 consecutive amino acids residues with a sequence present in SEQ ID NO 22 o
The binding of a peptide of interest to MHC is assessed based on its ability to inhibit the binding of a radiolabeled probe peptide to purified MHC molecules. This unit includes protocols for the purification of Class I and Class II MHC molecules by affinity chromatography, and for the ...
