Octet^® ProA Biosensors

For Determination of Antibody Concentration

• Direct measurement of immunoglobulins (IgG)
• Assay samples without centrifugation
• Fast turnaround of results
• Broad dynamic range
• Correlates to HPLC
• Direct measurement of immunoglobulins (IgG) 25ng – 2mg/mL

Octet^® ProA biosensors are coated with Protein A and enable rapid antibody quantitation from crude lysates, cell culture supernatants and complex matrices. The direct quantitation assay format of the Octet^® ProA biosensors provides ELISA data in less than 2 minutes and can be automated for high throughput screening efforts. Using an established pH-based regeneration protocol, the biosensors can be regenerated multiple times to provide a cost-effective and time-saving assay format.
