The Universal CPG (Controlled Pore Glass) type II, 1400 Å, is a universal support used to immobilize nucleosides for synthesizing oligonucleotides and to increase the rate of dephosphorylation of the 3′ end oligonucleotide during deblocking.
For the cleavage from the support and oligonucleotide deprotection, anhydrous ammonia gas-phase, ammonium hydroxide/methylamine mixture (AMA), and other basic reagents can be used in a short time. The Universal CPG type II 1400A is suitable for use in harsh conditions and makes cleavage and deprotection faster compared to universal supports. A pore size of 1400 Å is recommended for the synthesis of oligonucleotides 120-180 base pairs in length. For shorter oligos, use universal support universal support 500 Å and 1000 Å.
