Accurate quantification of a biotherapeutic, typically an antibody, is needed from cell line development and clone selection through to bioprocess development and production. To maximize productivity and efficiency, the assay format must therefore be reliable over a broad working range.

Data examples

Measure from picogram to milligram
Results demonstrate the broad dynamic range covered by two Gyrolab Bioaffy CDs. This ensures that the immunoassay platform can be used to quantify small amounts at low concentration during early development through to high concentration IgG titers in large-scale batch manufacturing.
Scalable assay format

Monitor IgG production during clone selection

Monitor IgG production during optimization of cell culture conditions
This work determined the effect of parameters such as temperature and media on the production of target IgG as well as HCP contaminants.
Efficient use of a multi-application platform
High reproducibility
Low coefficient of variation values demonstrated the high reproducibility achieved throughout the monitoring process.

Correlate with existing assay formats
Results correlate well with existing assays. Compared to conventional formats, the Gyros immunoassay platform consumes less sample and reagent, avoids the need for significant dilution before analysis and often offers greater throughput or automation capability.

Assay selectivity for IgG subclasses
Flexible assay format enables use of the optimal anti-IgG antibody to capture the target antibody of appropriate IgG subclasses.
Capture anti-IgG antibody selective for IgG1, IgG2 and IgG4, lacks significant affinity for IgG3 or IgM
