assay kits protein a
SKU: AK-AB-001

Format: Up to 320 Tests (5 Sensor Strips included)
Assay Format: Inverse occupancy using Protein A capture

Built for consistent, quantitative analysis of human IgG, this kit uses Protein A affinity capture and an inverse occupancy signal format. The design supports accurate performance across a broad dynamic range, even in crude cell culture supernatants.

With strong reproducibility and reduced setup burden, it’s ideal for antibody screening and early-stage process development.

This kit uses a dip-sensor format with Protein A pre-coating. During incubation, antibodies bind via Fc interaction, followed by detection of unoccupied binding sites to generate an inverse signal.

Parameter Typical Value
Sample throughput Up to 64 samples per run
Total run time ~75 – 200 min (format and setup dependent)
Hands-on time ~15 – 30 min
Detection range High: 1.88–240 µg/mL
Mid: 0.23–30 µg/mL
Low: 0.05–6.4 µg/mL
Format Inverse Occupancy (Protein A capture)
Assay Workflow Schematic. (1) Sensor surface coated with Protein A or Protein G. (2) Antibody (analyte) binds via Fc interaction. (3) Detection molecule binds remaining unoccupied Fc-binding sites, generating an inverse signal.

This assay supports reproducible mAb quantification across high, mid, and low concentration ranges. Performance is maintained in both clarified and crude matrices, ideal for decision-making in clone selection, screening, or upstream development.
