Figure 1. Accurate and rapid IgG titer determination is critical in the selection of cell lines and culture development for antibody production. ForteBio’s Octet QK and Octet RED Systems provide rapid and accurate IgG quantitation in a label-free format that is easy to use. The Octet family of instruments offers analytical capabilities that provide greater value in applications where existing methods such as HPLC and ELISA have limitations in throughput, performance, workflow, and ease of use. Principle Different protein concentrations…

Figure 1. Select promising leads earlier in the development process with the Octet RED system’s rapid, highly sensitive detection and label-free analysis of small peptides and small molecules. The Octet RED system’s rapid data acquisition and high sensitivity means that even the fastest reactions and smallest binders will be easily characterized. The Octet RED system shares the advantages of the Octet QK system: BLI technology, no microfluidics, eight-channel parallel processing, walk-away automation of up to 96 samples, and affordability —…

Figure 1. There are a variety of affinity tag-protein strategies, and the use of affinity tags depends on the target protein, the expression system, and the application. The Octet QK and Octet RED systems provide an easy-to-use, label-free, high-throughput system to capture affinity-tagged biologics for quantitative or kinetic biomolecular interaction analysis. Kinetic characterization of biologics during clone selection, screening, and development is critical at all stages of therapeutic engineering and bioprocessing. Key Applications Quantitative kinetic characterization (kobs′ ka′ kd′ KD…
