Binding kinetics were measured with the Octet RED96 instrument (ForteBio, Pall Corporation) using wildtype (wt) gp42 protein. Note: A buffer test needs to be conducted to determine the appropriate Assay buffer for each protein. In addition, the Octet® QKe system provides a High Sensitivity acquisition rate setting for both quantitation and kinetics assays, allowing measurement of lower ranges of protein concentrations and smaller molecular weight analytes than Octet® BLI System Quantitation Dynamic Range1 Octet® Biosensor Description Intended Use2 Application Octet ® QKe‡, QK384‡, RH96 ≥32 Channel Octet RED96e ‡, K2 , R2, R4, R8, RH16, RH96 8 or 16 Channel ® N1 Regeneration NTA (Cat. Note: Additional materials are required to run these assays. Bio-layer interferometry (BLI) real-time, label-free technology has greatly contributed to advances in vaccine research and development. The Octet BLI system has played an important role in assessing the CQAs of many monoclonal antibodies. If your binding assay development depends on being able to quickly identify assay conditions that retain membrane protein structure and activity, you need an instrument that will allow you to rapidly screen diverse assay environments and permit the use of a wide range of buffer components and additives. Briefly, biotylated RBD of SARS CoV-2 was diluted to a concentration of 5 μg/mL with PBST (PBS containing. 18-5060, 18-5063, 18-5064) Anti-Human Fc-Capture K Capturing human IgG’s. As for epitope-binding assays, proteins were biotinylated with a biotinylation kit for easy immobilization on streptavidin biosensors, and all experiments were also performed on the Octet Red 96 instrument with shaking at 1000 rpm. The Octet platform ofers an advanced fluidics-free approach with a wide variety of of-the-shelf Dip and Read biosensors for rapid binding kinetics and quantitation analysis. It can be used on the Octet® RH96, RH16 and QK384Octet BLI Discovery and Analysis Studio Software for kinetics and affinity data acquisition for drug-target binding and high-throughput kinetic screening for lead identification or concentration analysis of various biomolecules including IgG, Fab, custom proteins, and viruses. 96-Channel Ultra High Throughput Octet System: Octet ® RH96. The binding of selected sybodies to RBD or binding of RBD to ACE2 proteins was measured by biolayer interferometry (BLI) using the Octet RED96 system (FortéBio). It is ideal for rapidly measuring concentration of proteins and other biomolecules, measuring kinetics and affinity, and screening protein-protein and protein-small molecule interactions. The supernatant was collected after 6 days. The data analysis was done using Octet Data Analysis software,. 10. Eric Martin. ForteBio's new Octet RED96 system is a multi-functional, label-free, real-time analysis instrument. The Octet RED96e system directly measures the presence of specific proteins and other molecules in solution with minimal interference from complex matrices. CytoFLEX SRT Instrument. Available with automated analysis and 21 CFR Part 11 regulation compliance. Formal specification. , Ltd. The Octet platform based on bio-layer interferometry (BLI) technology is a whole set of system including instruments, biosensors, reagents and assay kits to support the evaluation of biomolecular interactions in 96- or 384-well microplates. 5A, SarA could speci c binding to hla promoter sequence which in line with previous report. The molecule of interest (“ligand”) is immobilized on the surface of a sensor, creating the biolayer. The Octet® QKe instrument contains the same high-perfor-mance spectrometer used in the Octet® RED96 system. 96 well ELISA plates were from Greiner bio-one (Germany). These fluidics-free, low-maintenance, sensitive systems. 6 nm was found to be optimal to measure a wide range of binding affinities on Octet HTX biosensor. Residual Protein A Detection Kit.
