What types of samples do you accept for the service?

We accept a wide range of input materials, including peripheral blood mononuclear cells (PBMCs), purified B-cell populations, fresh or frozen tissues, and high-quality total RNA. Our team can provide detailed guidance on optimal sample collection and preservation.

How does your method for eliminating PCR bias compare to 5' RACE-based approaches?

While 5' RACE is an improvement over multiplex PCR, it can still be subject to biases during the template-switching step and subsequent amplification. Our approach, integrating identifiers-based error correction and J-region priming, provides a more direct and robust method for absolute molecular counting, systematically correcting for biases introduced at multiple stages.

What is the typical turnaround time for a project?

The standard turnaround time, from sample receipt to delivery of the final analysis report, is typically 4-6 weeks. This may vary depending on the project scope and number of samples.

Can your platform perform paired VH-VL chain analysis?

Yes, our platform and expertise can be adapted for paired heavy (VH) and light (VL) chain sequencing from single B cells, providing complete information on the antigen-binding site. Please inquire for more details on this specialized service.

What are the key deliverables I will receive?

You will receive a comprehensive data package that includes the raw sequencing data (FASTQ files), processed and annotated clonotype tables, and a detailed final report. The report features publication-quality visualizations of key repertoire metrics, such as clonality, V(D)J gene usage, CDR3 length distribution, and SHM analysis, along with a thorough interpretation of the findings.

Revealing True Immune Diversity: The Imperative for Unbiased Profiling

The B-cell receptor (BCR) repertoire represents the complete collection of B-cell receptor sequences within an organism, forming the cornerstone of humoral adaptive immunity. Its immense diversity, generated through somatic V(D)J recombination and subsequent somatic hypermutation (SHM), endows the host with the capacity to recognize and neutralize a virtually limitless array of foreign antigens.

Key roles of the BCR repertoire:

Serves as a molecular chronicle of immunological history.
Provides a dynamic indicator of current immune status.
Perturbations in repertoire architecture are linked to infectious diseases, autoimmune disorders and malignancies.
Precise profiling is indispensable for Fundamental immunology research, Biomarker discovery, Next-generation antibody therapeutics.

However, conventional methodologies for BCR repertoire analysis, predominantly reliant on multiplex PCR amplification coupled with next-generation sequencing (NGS), are beset by significant technical biases.

Source of Bias	Impact on Repertoire Data
Differential primer affinities	Preferential amplification of certain V(D)J segments
PCR amplification skew	Overrepresentation of specific clones
Sequencing errors	Artificial diversity or false clonotypes
Stochastic sampling	Loss of rare but biologically significant clones

These biases distort the true frequency and diversity of BCR clonotypes, leading to skewed and unreliable results.
Recognizing this gap, Creative Biolabs' Unbiased BCR Repertoire Profiling Services are designed to overcome these challenges and provide a faithful representation of BCR diversity.
