Phase Detail
Clarity QSP
Clarity QSP 96-well plate and buffer system allows for purification of trityl on synthetic RNA and DNA

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.

  • Formats offer easy high-throughput processing for parallel purifications
  • Simple three step process delivers highly purified DNA/RNA in minutes
  • For oligos 10-100 mer
  • Economical and disposable format

U.S. Patent No. 7,119,145
