What is the minimum sample requirement for Repertoire Analysis?

Typically, we require at least 1×10^5 to 1×10^6 cells for a robust analysis, but we have optimized protocols for "small lymphocyte" populations with lower counts.

How do you handle PCR bias in NGS sequencing?

We primarily utilize 5' RACE and integrate Unique Molecular Identifiers (UMIs) during library preparation to track and correct PCR amplification bias, ensuring quantitative accuracy.

Can you provide TCR alpha/beta pairing information?

Yes, through our single-cell high-throughput sequencing platform, we can provide native pairing of TCR alpha/beta or BCR heavy/light chains.

Which species do you support?

We offer standard services for Human, Mouse, Rat, and Non-Human Primates (NHP). Custom primer design is available for other species like Camelids, Rabbits, and Chickens.

Do you provide bioinformatic support for data I already have?

Absolutely. Our bioinformatics team offers standalone Repertoire Analysis services for data generated on other platforms.

How deep should I sequence my repertoire?

Depth depends on the sample complexity. For a standard human PBMC sample, we typically recommend 2-5 million reads to capture the majority of the diversity.

Are your services compliant with clinical diagnostic standards?

Our services are intended for research use only (RUO). We provide high-quality data for discovery and preclinical phases but do not offer clinical diagnostic reports.

How do I get a quote for my project?

Cutting-Edge Technologies & Strategies of Our Repertoire Analysis Services

Advanced NGS Sequencing Strategies

We employ diverse NGS sequencing strategies, including 5' RACE (Rapid Amplification of cDNA Ends) and multiplex PCR. The 5' RACE approach is particularly advantageous as it minimizes PCR bias and captures the full V(D)J sequence, including the leader sequence, ensuring an unbiased representation of the Repertoire Analysis Services.

High-Throughput Sequencing Platform

Our facility is equipped with the latest equipment platforms. While this platform provides the high depth necessary for frequency analysis, and offers long-read sequencing that covers the entire transcript, facilitating better assembly of complex regions.

AI-Driven Bioinformatics Pipeline

Raw data is just the beginning. Our bioinformatics team utilizes machine learning algorithms to:

Perform V(D)J germline assignment and CDR3 identification.
Analyze clonal diversity.
Visualize rare clone expansion and public repertoire sharing.
Predict antigen specificity using structural modeling.

Applications of Repertoire Analysis

The insights gained from Repertoire Analysis Services are transformative across multiple biological domains:

Therapeutic Antibody Discovery

By analyzing the antibody repertoire of immunized animals or convalescent patients, we can rapidly identify high-affinity lead candidates. This bypasses traditional hybridoma limitations and accelerates the MemDX™ Therapeutic Antibody Discovery process.

Immunotherapy & Vaccine Development

Monitoring TCR repertoire changes post-vaccination or during CAR-T therapy provides critical data on immune activation, persistence, and clonal dominance.

Autoimmune & Infectious Disease Research

Identifying "public clones" (sequences shared between individuals) helps in understanding the common immune molecular patterns in response to specific pathogens or autoantigens.
