SdAb Repertoire Analysis Service

Overview Platform Workflow Why us Testimonials FAQ Resources

Overview

Single-domain antibodies (sdAbs), also known as V_HHs, represent a unique class of antibody fragments naturally derived from heavy-chain-only antibodies found in camelids and engineered across species. Their compact structure, stability, and high affinity make them invaluable in immunological studies, molecular recognition research, and biotechnological applications.

To truly understand the molecular diversity and binding potential of sdAbs, researchers require high-resolution repertoire analysis capable of profiling the full V_HH landscape with quantitative precision. At Creative Biolabs, we offer an advanced SdAb Repertoire Analysis Service built upon next-generation sequencing (NGS) technology. Our workflow combines experimental precision with powerful computational pipelines, allowing comprehensive identification and characterization of the sdAb population expressed in a given sample or immune repertoire.

Unlike generic sequencing services, Creative Biolabs' specialized approach is designed specifically for single-domain antibody frameworks. By leveraging optimized amplification strategies and stringent quality control, we ensure every sequence reflects biological authenticity rather than technical bias.

High-Definition Analytical Platform

Our sdAb repertoire profiling platform integrates high-throughput sequencing with a dedicated bioinformatics pipeline customized for the unique features of V_HH domains. Each dataset is processed through multiple layers of verification to deliver an accurate and interpretable view of repertoire diversity.

Our scFv repertoire analysis integrates wet-lab precision with high-fidelity, long-read sequencing and advanced informatics interpretation. The following core technologies define Creative Biolabs' platform:

Next-Generation Sequencing for Massive Parallel Coverage

Our NGS-based system enables millions of sequence reads in a single run, ensuring robust coverage of the sdAb repertoire while maintaining read-level accuracy through advanced quality scoring and error filtering.

Targeted Amplification of sdAb Framework Regions

Creative Biolabs employs specifically designed primer sets that anchor within conserved V_HH regions, ensuring efficient capture of the entire sdAb variable domain while minimizing amplification bias across diverse clones.

Rigorous Quality Control and Error Suppression

Each sequencing library undergoes quantitative evaluation at multiple stages—from cDNA integrity to base-level error filtering—to guarantee that results reflect the true biological composition of your sample.

Custom Bioinformatics Pipeline for V_HH Analysis

The computational workflow performs alignment, germline annotation, CDR region identification, and diversity metrics, generating an intuitive repertoire profile with clone frequency visualization.

Consult Creative Biolabs' specialists for an assessment of sequencing depth and library design appropriate to your sdAb samples.

Service Workflow

Creative Biolabs' workflow for sdAb repertoire analysis has been optimized for reliability and reproducibility across multiple sample types, ensuring each step contributes to high-quality sequencing and analysis results.

1. Sample Preparation and Validation

Researchers may submit total RNA, cDNA, or peripheral blood mononuclear cells (PBMCs) containing V_HH-expressing B cells. Each sample undergoes quality verification using spectrophotometry and integrity assessment prior to downstream processing.
2. RNA Extraction and cDNA Synthesis

High-purity RNA is isolated using Creative Biolabs' standardized protocols, followed by first-strand cDNA synthesis. Careful reaction optimization preserves the full-length sdAb sequence for accurate amplification.
3. Amplification of V_HH Variable Domains

Specially designed primers target the conserved leader and constant regions of the heavy-chain-only antibody gene. Amplified products are verified via gel electrophoresis before sequencing library construction.
4. Library Construction and Sequencing

Libraries are constructed using barcoded adapters, enabling multiplexing of samples within a single sequencing run. Sequencing is conducted on a next-generation platform offering high throughput and precise base calling.
5. Data Processing and Repertoire Profiling

Bioinformatics analysis includes read alignment, error correction, and clone clustering. CDR1, CDR2, and CDR3 sequences are identified, with mutation rates and V_HH gene usage analyzed to determine overall diversity and clonality.
6. Reporting and Consultation

Creative Biolabs delivers a comprehensive report summarizing repertoire characteristics, clone frequencies, diversity indices, and phylogenetic relationships. Our scientific team is available for discussion of the biological significance of your data.
