Modified Oligos
The addition of modification groups with various functions during oligo synthesis can support molecular biology studies for a variety of different purpose. There are five types according to the position of primer modification：5’-end modifications；3’-end modifications；2’-end modifications；Intermediate m🤡odifications；Nucleotide variant modifications.
DNA Modification Types Information
Here is a list of DNA modification and modification position that Generay can provide，Other modifications can be evaluated based o♐n the availability of raw materials.
