Octet^® GST Biosensors

For Quantitation and Kinetic Characterization of GST-tagged Biomolecules

• Direct and rapid quantitation of GST-tagged biomolecules
• Easy and reliable capturing of GST-tagged biomolecules for rapid kinetic analysis
• Designed for use in buffer or complex media

Glutathione-S-transferase (GST) is commonly fused to recombinant proteins to facilitate detection and purification, and to increase solubility. The Octet^® GST biosensors are coated with a high affinity anti-GST antibody. In conjunction with the Octet^® System, the GST biosensors provides a rapid and label-free method for GST-tagged protein quantitation and kinetic analysis. The high specificity of the antibody-based biosensor enables the direct quantitation of GST analytes in crude lysates, column eluents, cell lysates and cell culture supernatants, serving as an alternative to traditional time-consuming analytical methods.
