CpG Oligonucleotides (CpG ODN)

Inquiry

BOC RNA provides a variety of CpG oligonucleotides (CpG ODN) to help improve the immune stimulation response. All products are purified by HPLC and provided as lyophilized powder.

What is CpG ODN?

CpG oligonucleotides (CpG ODN) are short synthetic single-stranded DNA sequences that contain a relatively high proportion of cytidine-guanosine-dinucleotides (CpG). A typical CpG sequence motif consists of at least six nucleotides and a central CpG dinucleotide. Adjacent bases may be arbitrary and may include palindrome sequences.

CpG motifs are common in bacterial and viral DNA, but very rare invertebrates and cytosine is also mainly in methylated form. This difference in the structure of bacterial/viral DNA and vertebrate DNA can be recognized by the immune system, which means that due to its different DNA structures, potential pathogens can be identified very quickly and effectively.

Application and Classification of CpG ODN

Oligodeoxynucleotide (CpG ODN) containing unmethylated cytosine-guanine dinucleotide is a synthetic agonist of Toll-like receptor 9 (TLR9), which can activate humoral and cellular immunity and has been developed as a vaccine adjuvants to prevent or treat cancer, infectious diseases, and allergies.

Different types of CpG ODNs have different structural characteristics and immune functions. They are generally divided into three types: Type A, Type B, and Type C.

Type A
  • With a palindromic sequence containing CpG dinucleotide as its core
  • Poly G tails at both ends
  • Partial phosphorothioated modifications on the phosphodiester bond skeleton
  • Forming a high-level structure through the palindrome sequence and poly G tail to activate plasmacytoid dendritic cells and induce a large number of type I interferons
Type B
  • Linear CpG ODN modified with full phosphorothioates
  • Have strong immunostimulatory activity on B cells, but cannot activate plasmacytoid dendritic cells
Type C
  • Modified with full phosphorothioates
  • Form a dimer through the palindromic sequence, and have the activity of Class A and Class B CpG ODNs
  • Activate both plasmacytoid dendritic cells and B cells

Almost all CpG ODNs used in clinical trials are class B CpG (CpG-B) ODN (also known as K-type ODN). Class A CpG (CpG-A) ODN (also known as D-type ODN) has also been used, but in fewer clinical trials.
