Sample Types Tested
R&D Systems Biomarker Testing Service most often performs analysis using sample types that are typically evaluated during development of the R&D Systems assays. These include:
- Cell culture supernates
- Cell lysates
- Human breast milk
- Human saliva
- Other (custom evaluation available for unique sample types)
If a desired assay has not been validated for your sample type, custom sample-type evaluation is available by Biomarker Testing Service. Typical sample type evaluation includes:
- Spike and recovery to identify matrix interference
- Linearity of sample dilution
- Inter-assay precision & reproducibility (between different plates)
- Intra-assay precision & reproducibility (within a plate)
Sample type evaluations confirm that a particular assay is suitable for the sample type in question. Our Biomarker Testing Service team will also perform assays using kits that are not manufactured by R&D Systems.
