A rapid method to quantitatively screen bispecific antibody using protein A and His1K biosensors

Download the app note

Recent biotechnological advances have fueled development bispecific antibodies (bsAbs) in the last 10 years. However, the functional analysis of bsAbs during bioprocessing adds a challenge for scientists given the wide array of bsAbs populated by many different species, comprising many different formats, and that traditional SPR and ELISA methods for bsAbs evaluation are time consuming. Furthermore, cell line screening during bsAb production is based only on Protein A titer, where good pools and clone candidates might be discarded given the many antibody conformations that can be produced by cells.
