Redbud Labs - Model STR -Cartridge-Ready Sample Prep
Redbud Labs’s STR is the only cartridge-ready™ sample prep solution for microfluidic cartridges. STR (“sorter”) is a solid-phase affinity sorter that enables immuno-capture of analytes from complex samples such as whole blood. It supports sample volumes from microliters to milliliters and target sizes from nanometers to microns. STR streamlines sample prep in cartridge-based assays, enabling superior performance in applications across the life sciences industry.
Purify fast.
STR binds to your targets of interest, fast. The microfluidic agitation of Redbud Posts rapidly drives analytes to the binding surface, while off-target species are maintained in suspension, eliminating contamination. The result is unmatched purity and processing rates, across a wide range of target sizes, from molecules to cells, and across a wide range of sample types, from blood to growth media.
Concentrate low-level analytes.
STR has the power to concentrate analytes from larger concentrations of biospecimens. More analyte means higher sensitivity. Send a large sample through STR to concentrate rare analytes by 100x or more. Wash away then detect in place or release and elute for downstream analysis.
Customize by target.
Sample prep tools including microfuge tubes and magnetic beads are not amenable to cartridge development. STR delivers the flexibility of beads in an intrinsically microfluidic solution. STR features an easy-to-customize surface chemistry bound to our patented Redbud Posts enabling the assay developer to capture a variety of target sizes from a range of complex biospecimen volumes.
Minimize risk.
From biomarker discovery to diagnostic test production, whatever your application, STR is cartridge-ready. Choose to develop your assay using our modular starter kits. Design a protocol that fits your needs, whether it uses static chambers or continuous flow. Integrate sample prep wherever it’s needed, from a sample collection device to a detection system. Assemble your consumable in high-volume using standard equipment. STR enables both assay and system developers to work at the microfluidic level with the same component and get the same performance throughout thereby mitigating assay rework risks that are common in porting a benchtop assay.
