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.
