    High-Affinity Target BindingScalable Diagnostic & Biosensor Solutions

    We specialize in delivering end-to-end biotin aptamer services that empower researchers, diagnostic developers, and biosensor innovators to achieve precise and reliable results. By combining advanced SELEX technology, proprietary oligonucleotide chemistry, and proven biotin-streptavidin conjugation strategies, we create aptamers with superior affinity, stability, and versatility. Whether you need aptamers for small molecules, proteins, peptides, or complex targets, our custom development pipeline ensures rapid turnaround, reproducible performance, and seamless integration into your workflows-helping you accelerate innovation while reducing costs.

    What Problems Can Biotin Aptamers Solve?

    Low binding specificity in assays

    Aptamers selected and optimized for your target ensure strong affinity and minimal cross-reactivity.

    Challenges in immobilization or signal amplification

    Biotin-labeled aptamers leverage the biotin-streptavidin system for stable, efficient surface attachment and signal enhancement.

    Time-consuming antibody development

    Aptamers can often be generated faster, at lower cost, and with greater stability than conventional antibodies.

    Limited diagnostic sensitivity

    Aptamer-biotin conjugates improve detection limits in ELAA, LFA, biosensor chips, and other platforms.

    Scalability issues

    Synthetic aptamers are chemically defined and easily reproduced, ensuring consistent performance from R&D to production.
