DSP30
Based on 1 Customer Validation
DSP30 is a phosphorothioate cpG-oligodeoxynucleotide and a TLR9 agonist. DSP30 can activate immune system cells, including B cells and dendritic cells, by inducing proliferation and cytokine production.DSP30 can enhance the immunosuppressive function of bone marrow-multipotent mesenchymal stromal cells (BM-MSC). DSP30 combined with interleukin 2 (IL2) is an effective mitotic stimulant in B-cell disorders. DSP30 can be used for the genetic characteristic research and analysis of chronic lymphocytic leukemia (CLL).

Biological Activity
DSP30 (1 μM, 5 days) enhances the immunosuppressive function of BM-MSCs by promoting their proliferation, upregulating anti-inflammatory factors such as TGF-β1, maintaining high expression of IFN-γ and IL-10 in co-cultured T cells, and increasing the level of adenosine[1].
DSP30 (10 μg/mL, 5 days) enables CRTH2+ allergen-stimulated TH2 cells to produce IFN-γ[4].
DSP30 (0.1-1 μM, 0-72 h) significantly upregulates the expression of CD25 in B-CLL cells[5].
DSP30 (0.01-1 μM, 48-120 h) significantly enhances the killing effect of LMB-2 on B-CLL cells[5].
