Protein A (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

Protein A biosensors enable rapid antibody quantitation from crude lysates, cell culture supernatants and complex matrices. The direct quantitation assay format of the Protein A biosensor 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.
