CpG ODNs
CpG Oligodeoxynucleotide Manufacturing
What are CpG ODNs?
CpG oligodeoxynucleotides (CpG ODNs) are synthetic short single-stranded DNA molecules that contain unmethylated CpG motifs. These sequences mimic bacterial DNA and are recognized by the immune system via Toll-like receptor 9 (TLR9). Upon activation, CpG ODNs stimulate immune responses, making them valuable for enhancing vaccines, cancer therapies, and autoimmune disease treatments.
How CpG ODNs work
CpG ODNs bind to TLR9, which is predominantly found in certain immune cells like B-cells and plasmacytoid dendritic cells. This interaction triggers a cascade of immune responses, including the production of cytokines like interferon-alpha and interleukin-10. These immune responses help enhance the body's ability to fight infections, tumors, or respond to vaccines.
Key applications
- Vaccine Adjuvants: Enhancing the efficacy of vaccines by boosting antigen-specific immune responses.
- Cancer Therapy: Stimulating the immune system to recognize and attack tumor cells.
- Autoimmune Diseases: Modulating immune responses to potentially alleviate conditions like lupus.

CpG 7909
CpG 7909, also known as ODN 2006, PF-3512676, or Agatolimod, is a synthetic oligodeoxynucleotide immunostimulant composed of unmethylated CpG motifs with the power to activate the immune system through Toll-like receptor 9 (TLR9) signaling. Originally developed for cancer treatment and as an adjuvant for vaccines, CpG 7909 has shown promising properties.
CpG 7909 is commonly used as an adjuvant in a clinical setting for the testing of novel immunotherapeutic approaches. This compound can stimulate human B-cell proliferation, enhance antigen-specific antibody production, and induce interferon-alpha production, interleukin-10 secretion, and natural killer cell activity. This comprehensive immunomodulation makes it a valuable candidate in immunotherapy.
At BioSpring, CpG 7909 is manufactured using an established, multi-kilogram manufacturing process, ensuring reliability, safety, and consistency. It is produced following GMP standards to meet regulatory requirements and ensure the safety and efficacy of the therapeutic or vaccine candidate.
A DMF is available to speed up your IND. Customer access is facilitated by an authorization letter.
