BLI Technology for Monoclonal Antibody Assay

BLI Technology for Monoclonal Antibody Assay

The use of monoclonal antibodies is gradually changing the landscape of tumor treatment due to their specificity and efficacy. Cell lines capable of secreting highly effective monoclonal antibodies are usually obtained by transient or stable transfer, and cell expression needs to be monitored in real time during cell line selection. Biofilm interference is a non-labeled analytical detection technique based on optical interference signals for rapid detection of biomolecules. The principle is that the bottom end of the biosensor is covered by a biofilm layer, and when the biofilm layer is in contact with another molecule, the thickness of the biofilm layer increases, and after contact, the optical interference spectral shift changes at the sensor membrane layer, and the sample concentration is quantified by monitoring the shift change. CD BioSciences provide BLI technology for monoclonal antibody assay service to help customers complete biofilm related research.

Specific Monoclonal Antibody Assay Approaches We Offer

Specific Antibody Content Detection Approaches We Offer

  • CD BioSciences has developed a method for high throughput quantitative detection of monoclonal antibody concentrations using Biological Membrane Interference (BLI) technology.  We used OctetRed96 molecular interaction analyzer to detect antibody concentration based on the change of optical relative interference shift after binding of the sample to the protein A sensor, and to examine the methodology of this assay. The methodological investigation of this assay was carried out.
  • The protein A sensor binds specifically to the monoclonal antibody, and we can help determine whether the concentration of the antibody working standard shows a good regression with the binding rate by calculating the following data.
    • Correlation coefficient
    • Recovery rate
    • Relative Standard Deviation (RSD) of Repeatability
    • RSD of Intermediate Precision
