UL1-ACTIVA™ and UL1-HCE™ Frits contain a catechol-based universal linker (UL1) (J. O.C, 2007, 72 (26), pp 9875–9880)

 

UL1-ACTIVA™ frit

UL1- ACTIVA™ is the only commercial solid support featuring an amidite activating surface:

• ≥ 99.5% coupling efficiency
• Reagents Saving:
  • Up to 50 % lower reagent consumption relative to CPG columns
  • Up to 50 % amidite and activator saving
• Very low failure rate
• Direct desalting

UL1-HCE frit:

• A low cost frit using traditional reagents with 50mM Amidite and 250mM Activator for coupling.
• Same properties as ACTIVA™ frit with the exception of Amidite and Activator saving
