Assay formats: Recommendation for best practices and harmonization from the global bioanalysis consortium...

Area of Science:

• Bioanalytical science
• Assay development
• Biopharmaceutical analysis

Background:

• Ligand binding assays (LBAs) are crucial for biotherapeutic detection.
• The Global Bioanalysis Consortium (GBC) L3 assay format team reviewed common LBAs.
• International experts collaborated to harmonize practices.

Purpose of the Study:

• To review and compare major LBA platforms.
• To provide recommendations for platform selection and integration.
• To facilitate international harmonization of LBA practices.

Main Methods:

• Overview of discussions and global expert presentations.
• Analysis of common platforms including Gyrolab, Erenna, RIA, AlphaLISA, Delfia, Immuno-PCR, Luminex, BIAcore, and ELISAs.
• Focus on supporting bioanalysts in platform decision-making.

Main Results:

• Identified key platforms for biotherapeutic detection.
• Provided suggestions for platform integration and use.
• Highlighted the importance of analyte-specific needs in platform selection.

Conclusions:

• Harmonized practices and recommendations are essential for LBA implementation.
• Informed platform selection supports efficient biotherapeutic analysis.
• Integration into Good Laboratory Practice (GLP) environments is facilitated by expert recommendations.
