What type of canine samples can Creative Biolabs' accept for TCR repertoire profiling?

Creative Biolabs' accepts a broad range of canine-derived materials suitable for TCR sequencing, including peripheral blood mononuclear cells (PBMCs), splenocytes, lymph node suspensions, and tissue biopsies from experimental models. Both fresh and cryopreserved specimens can be processed, provided they meet minimum quality thresholds for RNA or DNA integrity. When possible, Creative Biolabs' recommends submitting freshly isolated PBMCs to ensure optimal template quality and accurate clonotype recovery. If samples must be frozen, our technical specialists can advise on the best storage and shipping conditions to minimize degradation.

What is the minimum sample input required for high-quality TCR profiling?

The minimal input depends on the experimental purpose and cell subset complexity. Generally, Creative Biolabs' sequencing pipeline can successfully analyze as few as several tens of thousands of T cells, thanks to optimized extraction and amplification protocols designed for limited material. However, for studies requiring in-depth repertoire coverage—such as monitoring rare or antigen-specific T cell populations—a higher number of cells is recommended to achieve sufficient sequencing depth and clonotype diversity.

Can formalin-fixed or low-viability samples be used?

While formalin fixation can significantly affect nucleic acid quality, Creative Biolabs has developed specialized workflows that can recover informative TCR sequence data even from partially degraded or low-viability samples. For FFPE-derived tissues, we employ a tailored extraction process and bioinformatics correction pipeline to enhance recovery of meaningful TCR information. Nonetheless, for the highest sensitivity and reproducibility, high-integrity RNA or DNA remains preferred.

How does Creative Biolabs ensure the accuracy of TCR diversity quantification?

Creative Biolabs employs a multi-step validation process combining molecular-level redundancy reduction, statistical modeling, and cross-sample normalization to ensure accurate quantification of clonotype abundance and diversity metrics. Each read is rigorously filtered to remove potential amplification artifacts and sequencing errors, allowing the resulting data to faithfully reflect the biological TCR repertoire. Additionally, Creative Biolabs' proprietary computational framework supports cross-study comparability, ensuring results are consistent and reproducible even when different experiments or cohorts are analyzed.

What kind of deliverables can I expect at the end of the service?

Clients receive a comprehensive data package that includes raw sequence files, clonotype abundance tables, diversity index summaries, V/J gene usage analysis, and visualizations. Optional add-ons include cross-sample comparison plots, diversity heatmaps, and hierarchical clustering of clonotypes across experimental groups. Each report is accompanied by a detailed methodological summary to facilitate transparent interpretation and reproducibility.

Canine (Dog) TCR Repertoire Profiling Service

Platform Workflow Features FAQ

Understanding the diversity and structure of the canine T cell receptor (TCR) repertoire is fundamental for advancing veterinary immunology, infectious disease studies, and vaccine development. As dogs are valuable translational models for immune-related research, analyzing their TCR landscape provides essential insights into how their immune systems respond to pathogens, allergens, and immunomodulatory interventions.

Creative Biolabs' offers a specialized Canine TCR Repertoire Profiling Service based on high-throughput next-generation sequencing (NGS). This approach allows for an unbiased and comprehensive examination of TCR diversity and clonality in dog samples, helping researchers uncover immune dynamics with precision and confidence. Our scientists at Creative Biolabs' combine molecular expertise with rigorous bioinformatics workflows to deliver reliable, publication-ready results.

Stepwise Service Workflow

Step 1. Sample Collection and Assessment

Samples such as peripheral blood mononuclear cells (PBMCs), spleen, or lymph node tissues are accepted for profiling. Upon arrival, each specimen undergoes integrity and RNA quality evaluation to guarantee that only high-quality material proceeds to library construction.
Step 2. RNA/DNA Isolation

Our extraction workflow is optimized for canine immune tissues, ensuring high-purity nucleic acids with minimal degradation. Creative Biolabs' employs tailored buffers and gentle purification steps to maintain template quality for downstream amplification.
Step 3. TCR Library Preparation

Target-specific amplification strategies are applied to capture the canine TCR α and β chains comprehensively. Each library is carefully balanced to reflect native clonal distributions without overamplification, maintaining an unbiased repertoire profile.
Step 4. Sequencing and Data Capture

High-throughput sequencing generates millions of reads per sample, allowing for deep coverage across variable, diversity, and joining gene segments. This enables accurate reconstruction of CDR3 regions—the key determinants of TCR specificity.
Step 5. Bioinformatics and Data Interpretation

Creative Biolabs' proprietary analysis pipeline processes raw sequence data through quality trimming, alignment to reference databases, clonotype clustering, and diversity index computation. The resulting dataset provides a detailed snapshot of TCR composition, frequency, and complexity in each sample.
Step 6. Deliverables and Reporting

Final outputs include summary statistics, visualizations (clonotype frequency plots, diversity curves, and gene usage maps), and annotated sequence tables. Optional comparative analyses between treatment groups or time points are available upon request.
