Buy now Advancing antibody discovery The First Regenerable Streptavidin Biosensor Break free from costly, one-sample-per-sensor workflows with the Gator® Regen SA (RSA) Biosensor. Regenerate, reuse, and reduce cost without compromising performance. Streptavidin biosensors have always been one-and-done. Load your biotinylated target, run the interaction, discard the probe. Regen SA (RSA) probes change that. Built on an engineered streptavidin, RSA regenerates with the same standard protocol you’d use on any reusable capture surface, so a single probe measures up to 10 interactions. Paired with Gator Bio’s XT optics, RSA delivers up to 4x higher signal at up to 8x lower cost per interaction than non-reusable SA sensors. Download Flyer Consistent recapture across a wide dynamic range RSA probes demonstrate robust regeneration performance using the proprietary Regeneration Solution for RSA which effectively removes both the bound ligand and analyte while leaving the streptavidin layer intact. Consistent loading height with recovery of 90-110% is achieved across 10 recapture cycles. 10 recapture cycles of hIgG labeled with biotin-LC-LC on RSA probes at concentrations of 0.625 – 80 μg/mL demonstrating 1.3-5.8% CV on signal loading with 90-110% recovery across all concentrations. Kinetic characterization of biotinylated CRP and PD-L1 with their respective antibodies on the same set of RSA probes with alternating recapture cycles. Capture and screen multiple biotinylated samples with a single reusable biosensor Move through your screening libraries more efficiently by capturing up to 10 different biotinylated samples on the same probe with reliable results. Maintain consistent kinetic performance by using same biosensor for multiple samples. Up to 4x higher signal enabled by XT optics technology XT optics technology increases the signal per bound molecule, improving total signal up to 4x and allowing users to use load fewer ligand molecules to get the same amount of signal as traditional BLI biosensors. This allows users to limit mass transport and avidity effects with ease. Comparison of signal height for CRP/antiCRP kinetics interaction on (A) SA probes and (B) RSA probes. “The Regen SA probes have been an absolute game-changer for our kinetics screening workflows. What we love most is the streamlined, simple workflow; it operates exactly like any other reusable capture assay, allowing us to increase our sample throughput and save us valuable time. We’ve been so impressed that we plan to adopt Regen SA as our primary probe for biotin-tag capture assays.” Sr. Scientist, Commercial Discovery group Key Features Reuse for up to 10 recapture cycleswith consistent loading height performance (≤ 6% CV) Decrease cost per interaction by up to 8xcompared to non-reusable streptavidin biosensors Screen up to 960 samples with a single tray of 96 RSA probes Up to 4x higher signal compared to standard streptavidin sensors Uses a standard regeneration workflow with the kit’s regeneration reagent, maximizing throughput Convenient kit provides all required regeneration reagents and protocols Previous Next Ready to see Regen SA in your lab?
