Phosphate CPG 500 solid support is a solid support for the synthesis of 3′-phosphorylated oligonucleotides. The phosphate group can be used as a blocking functionality to prevent 3′-5′ exonuclease activity of some polymerases.Upon cleavage from the support, a phosphate group remains at the 3′ end of the oligonucleotide. It does not require any changes in oligo synthesis and deprotection protocols.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
