The Octet Protein G (ProG) Biosensors provide rapid and direct quantification of mammalian IgGs, enhancing bioprocess efficiency. With pre-immobilized Protein G, they outperform Protein A, making them ideal for applications like hybridoma screening. Their regenerable format ensures cost-effectiveness and minimal sample handling, delivering precise results quickly. Compatible with Octet systems, they facilitate seamless antibody concentration determination, offering a dynamic range from 0.05 to 2000 µg/mL.
