Clarity SPE
The Clarity BioSolutions sample preparation portfolio is composed of unique solid phase extraction chemistries packed in 96-well plate and cartridge formats designed to efficiently and effectively purify oligonucleotides.
- Works for desalting and clean up of biological samples
- Specially formulated buffer solutions available for optimal performance
- Quick protocols for rapid LC-MS/MS results
- No liquid-liquid extractions (LLE)
Oligonucleotide Purification Products
Clarity OTX™ Extraction Kits
Prior to LC-MS analysis, therapeutic oligonucleotides must be isolated from interferences such as salts, sugars, large proteins, and genomic DNA. Using a mixed-mode solid phase extraction (SPE) sorbent in conjunction with carefully formulated buffers, Clarity OTX consistently delivers high recoveries.
Clarity QSP™ High-Throughput Purification
Purify trityl-on synthetic DNA or RNA samples in 20 minutes using Clarity QSP 96-well plate and buffer system. Final elution delivers >90 % typical purities/recoveries for in vivo applications and downstream analysis by LC-MS or CE.
Clarity RP-Desalting™ Quick Salt Removal
Clarity RP-Desalting tubes utilize reversed phase, in lieu of size exclusion, to eliminate salt and reagent from trityl-off synthetic oligo mixtures in order to capitalize on the speed and loading capacity benefits.
