At Creative Peptides, we provide integrated custom MHC-peptide tetramer services for research teams that need a coordinated workflow from antigen peptide selection to tetramer-based T cell analysis. Our service scope covers peptide antigen design, T-cell epitope identification, custom peptide synthesis, pMHC monomer preparation, biotinylated monomer generation, MHC class I and class II tetramer assembly, fluorescent labeling, and tetramer-based detection or sorting support. This page serves as an overview of the full service chain and helps users identify the most suitable entry point based on their antigen information, peptide status, allele requirements, and downstream study goals.
MHC-peptide tetramer projects often involve more than a single reagent preparation step. Many research teams begin with a target antigen but still need support in narrowing peptide candidates, confirming peptide quality, selecting a suitable pMHC format, and aligning tetramer preparation with downstream staining or sorting plans.
An integrated service workflow helps reduce these handoff gaps by connecting each stage of the project from the start.
We provide a connected suite of MHC-peptide tetramer services covering antigen peptide design, custom peptide synthesis, pMHC monomer generation, biotinylated monomer preparation, MHC class I and class II tetramer assembly, fluorescent labeling, and tetramer-based T cell detection and sorting support. Each module can be used as a standalone service or combined into a more complete workflow depending on project stage, antigen information, allele requirements, and downstream assay goals.
MHC-peptide tetramer projects often start with practical questions rather than a finalized reagent specification. We help define a workable service route based on the target antigen, available peptide information, MHC allele, intended species, and the downstream use of the final reagent.
For projects that begin from a target protein or antigen rather than a validated peptide, we support antigen peptide design and epitope prioritization to improve the chances of obtaining useful downstream tetramer reagents.

For projects that go beyond detection and require viable antigen-specific cell recovery, we support tetramer-positive T cell sorting workflows that can connect with downstream functional or molecular analysis.
Different MHC-peptide tetramer projects start from different points. Some users already have a validated epitope and only need peptide synthesis or tetramer preparation, while others require support from antigen review through downstream T cell detection. The table below helps match common research needs with the most suitable service module and typical next step.
| Project Need | Recommended Service Module | Typical Starting Input | Main Deliverable | Typical Next Step |
|---|---|---|---|---|
| Need to identify candidate peptides from a target antigen | Epitope Design | Antigen or protein sequence, species, allele information if available | Prioritized peptide candidates for downstream tetramer development | Custom antigen peptide synthesis |
| Need research-grade peptide material for tetramer preparation | Peptide Synthesis | Defined peptide sequence, purity expectation, quantity requirement | Custom antigen peptide with analytical confirmation | pMHC monomer production or direct tetramer preparation |
| Need a flexible intermediate before multimerization | pMHC Monomers | Peptide sequence and matched MHC allele | Peptide-loaded pMHC monomer reagent | Biotinylation, tetramer assembly, or custom downstream format selection |
| Need a streptavidin-compatible intermediate for downstream assembly | Biotinylated Monomers | Peptide sequence, allele, and intended labeling strategy | Biotinylated pMHC monomer for tetramerization | Fluorescent or application-specific tetramer preparation |
| Need to detect antigen-specific CD8+ T cells | MHC-I Tetramers | Class I-restricted peptide epitope and matched allele | MHC class I peptide tetramer reagent | Flow cytometry staining and downstream phenotyping |
| Need to detect antigen-specific CD4+ T cells | MHC-II Tetramers | Class II-relevant peptide region and matched allele | MHC class II peptide tetramer reagent | Flow cytometry detection and helper T cell analysis |
| Need a flow-ready reagent for multicolor analysis | Fluorescent Labeling | Tetramer format requirement and preferred detection channel | Fluorescently labeled MHC-peptide tetramer | Tetramer staining and flow panel integration |
| Need to quantify or phenotype antigen-specific T cells | T Cell Detection | Tetramer reagent, sample type, and staining workflow goal | Tetramer-based detection strategy for flow cytometry analysis | Comparative immune profiling or rare-population analysis |
| Need viable tetramer-positive cells for downstream studies | Cell Sorting | Tetramer reagent, expected target frequency, and downstream use plan | Tetramer-positive T cell sorting workflow support | Functional assays, sequencing, or ex vivo expansion studies |
Not every project should begin with the same reagent format. Some teams need upstream design support, some need a peptide-loaded monomer for a flexible downstream workflow, and others need a fully labeled tetramer ready for direct flow cytometry use. The table below connects common project goals with the most suitable service route.
| Research Goal | Recommended Format | Typical T Cell Focus | Key Input Needed | Main Technical Consideration |
|---|---|---|---|---|
| Screen candidate epitopes first | Epitope design support plus custom antigen peptide synthesis | CD8+ or CD4+ depending on allele strategy | Antigen sequence, species, target allele set | Peptide-MHC fit should be reviewed before reagent manufacturing |
| Keep downstream format flexible | pMHC monomer or biotinylated pMHC monomer | CD8+ or CD4+ pathway planning | Peptide sequence, allele, intended labeling route | Monomer format should match later tetramer assembly and assay needs |
| Detect antigen-specific CD8+ T cells | MHC class I peptide tetramer | CD8+ T cells | Class I allele and short peptide epitope | Peptide affinity and control design affect staining quality |
| Detect antigen-specific CD4+ T cells | MHC class II peptide tetramer | CD4+ T cells | Class II allele and target peptide region | Low-frequency populations often need careful staining strategy |
| Run multicolor phenotyping panels | Fluorescently labeled tetramer | CD8+ or CD4+ subsets | Instrument channels and antibody panel plan | Fluorochrome choice should fit compensation and marker layout |
| Recover viable positive cells | Tetramer-based detection plus sorting workflow support | Antigen-specific T cell populations | Sample type, expected frequency, downstream use | Rare-cell recovery and viability planning should be built in early |
End-to-End Continuity
