What sample types are suitable for γ/δ profiling?

Creative Biolabs supports a wide variety of sample types, including PBMCs, tissue-derived T cells, enriched subsets, and low-input samples. Each sample undergoes quality assessment upon receipt, and Creative Biolabs provides detailed guidance on collection, storage, and shipping to preserve T cell viability and RNA/DNA integrity. For tissue samples, we offer protocols for mechanical and enzymatic dissociation, ensuring optimal recovery of γ/δ T cells.

Can Creative Biolabs detect rare γ/δ clones?

Yes. Creative Biolabs employs ultra-deep sequencing enabling reliable detection of rare γ/δ T cell clones, even those comprising less than 0.01% of total T cells. This high sensitivity allows researchers to capture early clonal expansions or subtle immune events that conventional methods might miss.

Are Vγ and Vδ subpopulations distinguished?

Absolutely. Creative Biolabs' computational pipeline can resolve specific Vγ and Vδ subpopulations, such as Vγ9Vδ2 or Vδ1 cells, and provide detailed analyses of clonal distribution, dominance, and diversity. This enables researchers to study subset-specific immune responses and understand the role of distinct γ/δ populations in different tissues or conditions.

Can Creative Biolabs compare repertoires across experimental conditions?

Yes. Creative Biolabs supports comparative analysis across time points, treatment groups, or tissue types. The pipeline can detect clonal expansions, contractions, and shifts in diversity, allowing researchers to track immune dynamics and identify key functional γ/δ clonotypes in different experimental contexts.

Can Creative Biolabs analyze both RNA and DNA-derived TCR sequences?

Yes. Creative Biolabs can process RNA for transcript-based TCR profiling, providing insights into actively expressed clonotypes, or DNA for comprehensive genomic repertoire analysis, including low-frequency and quiescent clones. This flexibility allows researchers to choose the approach that best fits their experimental goals.

TCR γ/δ Repertoire Profiling Service

Platform Workflow Features Testimonials FAQ

T cells expressing γ/δ T cell receptors (TCRs) represent a unique and functionally versatile arm of the immune system, distinct from conventional α/β T cells. γ/δ T cells play important roles in tissue surveillance, early immune responses, and recognition of non-peptide antigens, yet they constitute a minor fraction of the total T cell population, making comprehensive profiling challenging.

At Creative Biolabs, our TCR γ/δ Repertoire Profiling Service is designed to provide high-resolution, quantitative analysis of γ/δ T cell populations. By combining enrichment strategies, next-generation sequencing (NGS), and advanced computational analysis, Creative Biolabs enables researchers to uncover γ/δ T cell diversity, identify clonotypes, and monitor repertoire dynamics across experimental conditions.

This service is particularly valuable for basic research in immunology, infectious disease models, tumor immunology, and developmental studies, offering insights into how γ/δ T cells contribute to overall immune responses.

Platform: Cutting-Edge Tools for γ/δ TCR Profiling

Creative Biolabs' platform integrates multiple technological layers to ensure high sensitivity, accuracy, and reproducibility in γ/δ TCR profiling:

1. Targeted γ/δ TCR Enrichment

Creative Biolabs uses optimized primers and amplification protocols specifically designed to capture both TCR γ and TCR δ chains. This targeted enrichment allows detection of rare clonotypes while minimizing amplification bias. Our platform supports analysis of total γ/δ populations or subset-specific enrichment, including Vγ and Vδ subpopulations, providing a comprehensive overview of γ/δ repertoire composition.

2. Ultra-Deep Next-Generation Sequencing (NGS)

High-depth sequencing ensures detection of low-frequency γ/δ T cell clones, even when these cells represent a minor fraction of total T cells. Sequencing coverage is adjusted according to sample type, expected cell counts, and research goals, guaranteeing reliable identification of rare clonotypes.

3. IMGT-Based Computational Annotation

All sequences are aligned to the IMGT reference database, allowing precise identification of V, D, and J gene segments. This standardized annotation supports consistent clonotype nomenclature, enabling reproducibility and facilitating cross-study comparisons. Researchers receive data that is publication-ready and compatible with downstream bioinformatics analyses.

4. Flexible Sample Compatibility

Creative Biolabs' γ/δ profiling platform accommodates a wide range of sample types, including PBMCs, tissue-derived T cells, enriched subsets, and low-input samples. Protocols are optimized to maintain cell viability and sequence integrity, ensuring high-quality data regardless of input material.
