Capable of maintaining cell health over long periods for multiple microplates

The oxygen radical absorbance capacity (ORAC) assay is an analytical method to determine the antioxidant potential of nutraceutical, pharmaceutical and food ingredients.

Automated biological testing can take on many forms, ranging from individual instruments performing a single task to large, room-sized, custom-robotic systems capable of automating very complex tasks. In between these two extremes are simple modular automated systems designed to automate a select series of tasks necessary for a specific assay technology.

Microplate-based multiplex assays, where microspheres are used as solid support matrices, provide simultaneous analyte analysis per well with lower background noise and reagent, consumable and sample costs compared to traditional ELISAs. Specifi

While other common types of contamination are usually quickly identified and/or treated, mycoplasma contamination often provides no clear symptoms but can wreak havok on assay results.
