Uses:
Dextran Sulfate Sodium Salt (DSS)
Dextran Sulfate Sodium Salt (DSS) is a synthetic, polyanionic polysaccharide derived from dextran — a complex glucose polymer — through esterification with chlorosulfonic acid. It exists as the sodium salt form and is typically supplied as a white to off-white, hygroscopic powder that is freely soluble in water, forming a clear, colorless to slightly yellow solution.

Core Uses & Applications
1. Inflammatory Bowel Disease (IBD) Animal Modeling — The Gold Standard
This is by far the most prominent and widely recognized application of DSS. When administered orally via drinking water (typically 2–5% w/v for 5–7 days), DSS reliably induces colonic inflammation in mice and rats that closely mimics human ulcerative colitis (UC) and Crohn's disease (CD).
How it works:
DSS binds to mucosal epithelial cell surface mucins, disrupting the intestinal barrier
It inhibits epithelial cell proliferation and promotes apoptosis, increasing gut permeability
Gut microbiota and their products (e.g., lipopolysaccharide) translocate into the submucosa
This triggers innate immune cells (macrophages, dendritic cells) via pattern recognition receptors (e.g., Toll-like receptors) to release pro-inflammatory cytokines (IL-6, IL-1β, TNF-α)
Neutrophils and lymphocytes infiltrate, creating a cascade of inflammation
Model types achievable:
Acute colitis — single cycle of DSS drinking water (5–7 days)
Chronic/relapsing colitis — multiple cycles of "DSS water → normal water"
Colitis-associated cancer (CAC) — DSS combined with azoxymethane (AOM)
Optimal molecular weight: 36,000–50,000 Da DSS produces the most stable and reproducible colitis induction.
2. Molecular Biology — Nucleic Acid Hybridization Accelerator
DSS (especially high molecular weight, >500 kDa) is widely used in molecular biology as a molecular crowding agent to accelerate nucleic acid hybridization in techniques such as Southern blot, Northern blot, and fluorescent in situ hybridization (FISH).
At 10% concentration, DSS can increase DNA probe hybridization rates by 10- to 100-fold
It works by occupying solution volume, effectively excluding nucleic acids and raising their effective local concentration
3. Lipoprotein Precipitation & Clinical Chemistry
In the presence of Mg²⁺ ions, DSS selectively precipitates low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL) from serum, leaving high-density lipoprotein (HDL) in the supernatant. This is a standard method for HDL cholesterol quantification in clinical diagnostics.
4. Antiviral Research
DSS exhibits antiviral activity by binding to positively charged regions on viral surface proteins, preventing viral adsorption to host cells. It has demonstrated inhibitory effects against:
HIV-1 — blocks viral attachment
Herpes simplex virus
Influenza virus
Lower molecular weight DSS (e.g., 5 kDa) also inhibits complement and coagulation pathways and prevents NK cell-mediated cytotoxicity.
5. Immunology Research
DSS modulates immune responses in several ways:
Polyclonal activation of B lymphocytes (even immature B cells)
Enhancement or suppression of humoral immunity
Modulation of thymocyte reactivity to lectins
Enhancement/suppression of cell-mediated immune responses
Acts as an adjuvant in certain immunization protocols
6. Anticoagulant & Anti-lipemic Agent
DSS has heparin-like activity (~17 international heparin units/mg), acting as an anticoagulant by inhibiting blood coagulation factors and platelet aggregation, and enhancing fibrinolysis. It has been used clinically (under trade names like Aspro and Colyonal) as an antithrombotic and lipid-lowering agent.
7. Drug Delivery & Biomaterials
DSS serves as a polyanionic cross-linker for chitosan, enabling the fabrication of microparticles and nanoparticles for controlled drug delivery systems. It is also used in hydrogel formulations and tissue engineering scaffolds.
8. Cell Culture Additive
In CHO (Chinese Hamster Ovary) cell cultures, DSS has been shown to influence recombinant monoclonal antibody production, affecting cell growth, productivity, and key quality attributes such as aggregation, charge variants, and N-glycosylation profiles.
