Aptamer Screening Services for Metal Ion

Unlocking Precision Detection with Aptamer Screening Services for Metal Ions

In an era where precise detection and quantification of metal ions are critical for environmental monitoring, biomedical research, and industrial safety, KMD Bioscience offers cutting-edge Aptamer Screening Services for Metal Ions. Our specialized services harness the power of aptamer technology to deliver highly specific, sensitive, and reliable solutions for metal ion detection and analysis.

Why Aptamers for Metal Ion Detection?

Aptamers are single-stranded DNA or RNA molecules that bind to specific targets with high affinity and selectivity. When it comes to metal ions, aptamers offer distinct advantages over traditional methods like atomic absorption spectroscopy or ion-selective electrodes:

• Exceptional Specificity: Aptamers can distinguish between metal ions with similar chemical properties (e.g., different oxidation states of the same metal or ions of similar size and charge).

• High Sensitivity: They enable detection at very low concentrations, often in the nanomolar or picomolar range.

• Versatility: Aptamer-based sensors can be engineered into various formats, including colorimetric, fluorescent, and electrochemical platforms, for adaptable application.

• Robustness and Stability: Aptamers are chemically stable, easily synthesized, and modifiable, making them ideal for development into field-deployable detection kits.

Our Comprehensive Aptamer Screening Service

At KMD Bioscience, we provide an end-to-end service to develop custom aptamers tailored to your target metal ion. Our process leverages the Systematic Evolution of Ligands by Exponential Enrichment (SELEX) technology, enhanced by our proprietary advanced screening and optimization platforms.

Our Service Workflow:

1. Project Consultation & Target Definition: We collaborate with you to define the specific metal ion target (e.g., Pb²⁺, Hg²⁺, Cd²⁺, As³⁺, Cu²⁺) and the desired performance parameters (sensitivity, specificity, buffer conditions).

2. Library Design & SELEX Selection: Our experts design and synthesize a diverse random oligonucleotide library. Using state-of-the-art SELEX procedures, we iteratively select and enrich sequences that bind tightly to your target metal ion.

3. High-Throughput Sequencing & Bioinformatics Analysis: Next-generation sequencing (NGS) of enriched pools is combined with advanced bioinformatics to identify candidate aptamer families and predict their binding structures.

4. Characterization & Validation: The binding affinity (Kd), specificity (against interfering ions), and sensitivity of lead aptamer candidates are rigorously validated using techniques like isothermal titration calorimetry (ITC), surface plasmon resonance (SPR), or fluorescence-based assays.

5. Sensor Development & Delivery: We deliver the fully characterized aptamer sequences. Furthermore, we offer optional downstream development services to integrate the aptamer into a functional detection platform (biosensor) tailored to your application needs.
