Download this application overview which. All measurements were performed using the Octet RED96 system (FortéBio, Molecular Devices) at 30°C and 1000 rpm. The Bio-Layer Interferometry (BLI) technology used in the Octet platform offers a simple Dip and Read ™ microfluidics-free approach to biomolecular interaction analysis. The results obtained by the Octet quantification assay were compared to a commercially available ELISA sandwich assay. Sartorius AG octet red96 device Octet Red96 Device, supplied by Sartorius AG, used in various techniques. For soluble glycopolypeptides, biotinylated ligands (200 nM) in phosphate-buffered saline (PBS) with bovine serum albumin (BSA) (0. Kinetic measurements were performed using an Octet Red 96 System (Pall FortéBio/Sartorius) at 25°C with shaking at 1000 rpm. Don’t miss a eureka moment!

ForteBio, a supplier of label-free technology, has launched Octet RED96 System, as well as its new Dip and Read Protein L Biosensor for use on the Octet platform. The validation of 2D-HFn and HFn binding to integrin α2β1 assayed with BLI. Values of KD (M), ka (1/Ms), and kd (1/s) were determined using the Octet RED96 system. 01 mg/mL) and mutant variants (0.
