Designed for scientists working across antibody discovery, cell line development, and process optimisation, the Protein A and Protein G kits provide ready-to-use solutions for quantitative antibody measurement.
Each kit includes pre-coated sensor strips, assay plates, and reagents for seamless integration with the Amperia™ system. Protein A enables robust IgG quantification across subclasses, while Protein G extends coverage to a broader range of species and isotypes. Both kits use an inverse-occupancy assay format with electrochemical detection, ensuring reliable performance across users, runs, and sample types.
Key Features:
- Ready-to-use format tailored for the Amperia™ system
- Fc-based capture with inverse-occupancy detection
- Up to 320 tests per kit (5 sensor strips, 10 plates included)
- Compatible with crude harvests and clarified samples
- Extended subclass and species coverage with Protein G
- Validated for reproducibility across runs and users
Applications:
- Antibody titre monitoring in R&D and process development
- Clone screening and cell line selection
- Comparative analysis of antibodies across subclasses
- Bioprocess optimisation
Supporting antibody quantification in biologic development
Monoclonal antibodies (mAbs) remain one of the most widely used therapeutic modalities across oncology, autoimmune diseases, and infectious diseases.
In this application note, Abselion demonstrates the Amperia™ platform, offering a streamlined alternative, enabling consistent, sensor-based mAb quantification directly from cell culture supernatants using an inverse occupancy assay format, with adaptable throughput and simplified setup.
TechTalk: Fast, accurate, accessible quantification across diverse biologics
Friday, January 23 at 16:00 GMT | 17:00 CET | 11:00 EST | 08:00 PST
Quantifying antibodies, AAV capsids, and tagged proteins directly from crude or partially clarified samples remains a common bottleneck in many biologics workflows.
In this 20-minute SelectScience TechTalk, Dr. Paolo Romele, VP of Science, Abselion will introduce the electrochemical approach used in the Amperia™ benchtop platform, which combines affinity-based capture with Redox Electrochemical Detection (RED) to provide quantitative measurements without relying on optical readouts.
Join this educational and technology-focused session to learn practical examples illustrating how these assays operate across biologics applications.
