The Sartorius Octet Anti-Penta-HIS Biosensors are high-affinity, fiber optic biosensors designed for the rapid, label-free quantitation and kinetic analysis of His-tagged proteins. Their exceptional specificity and ability to directly capture proteins in complex samples distinguish them from traditional methods, enabling efficient workflows in protein analysis. Compatible with Octet BLI systems, they provide significant advantages in kinetic applications and can be regenerated, making them a cost-effective solution for researchers.
