The Universal CPG type II, 500A is used for oligonucleotides synthesis to increase rate of dephosphorylation of the 3' end oligonucleotide during deblocking due to a rigid bicyclic molecule on the support.

The Universal CPG type II, 500A is suitable for use in harsh conditions and makes cleavage and deprotection with anhydrous ammonia gas-phase, ammonium hydroxide/methylamine (AMA) mixture or other basic reagents faster compared to universal Controlled Pore Glass (CPG) supports. Pore size of 500 Å is recommended for the synthesis of oligonucleotides up to 120 bases. For oligos up to 120 bases universal support 1000 Å can be used.

Usage

Coupling: Standard conditions for universal CPG.

Deprotection: 2 hours at 80°C or 8 hours at 55°C using concentrated ammonia; 15 minutes at 65°C using AMA mixture, ammonium hydroxide - 40% methylamine (1:1).
