DEAE-Dextran, or diethylaminoethyl dextran, is a cationic polysaccharide derivative widely used as a non-viral transfection reagent in molecular biology, virology, and pharmaceutical research. Chemically, it's produced by substituting dextran—a glucose polymer—with diethylaminoethyl (DEAE) groups, imparting a positive charge at neutral pH (pKa ~9.5). This polycationic nature enables it to bind negatively charged DNA/RNA, forming complexes that facilitate cellular uptake via endocytosis.
Discovered in the 1950s, DEAE-Dextran revolutionized gene delivery. Early applications included virus concentration for vaccine production (e.g., poliovirus precipitation). By the 1970s, it became a staple for DNA transfection in mammalian cells, offering 10-100x higher efficiency than naked DNA. Today, in 2026, demand surges with CRISPR/Cas9 and mRNA therapeutics—global market projected at $250M (Grand View Research, 2025), driven by USA biotech hubs like Boston and San Francisco.
Key properties: High molecular weight (40-500kDa tunable), water solubility (>50mg/mL), low toxicity (LD50 >5g/kg), and stability (shelf-life 3+ years at 4°C). Grades vary: Transfection-grade (MW 500kDa, purity >98%) for labs; Pharmaceutical-grade (DMF/FDA-compliant, endotoxin <0.1EU/mg) for GMP production. Mechanism: Forms toroids with nucleic acids, protects from nucleases, and promotes lysosomal escape—ideal for hard-to-transfect cells like HEK293, COS-7.
Applications span:
Compared to Lipofectamine® (expensive, cytotoxic), DEAE-Dextran cuts costs 80% with comparable efficiency in suspension cells. In USA, FDA 21 CFR 211 compliance mandates low pyrogens/heavy metals—our product excels here. Market trends: By 2026, personalized medicine drives bulk demand (tons/year), with Asia supplying 60% volume but only 20% quality-certified (USP data).
Synthesis involves dextran activation with epichlorohydrin/DEAE, purification via ion-exchange. Specs ensure batch-to-batch consistency: Nitrogen content 3-4%, substitution degree 0.4-0.5 meq/g. Safety: Non-genotoxic (Ames negative), biodegradable. Regulatory: Compliant with USP-NF, Ph.Eur.; USA imports qualify under cGMP.
For procurement: Bulk pricing $150-300/kg (vs. competitors' $600+), MOQ 1kg-tons. OEM/ODM: Custom MW, sterile lyophilized formats. Logistics: DHL/FedEx 5-7 days to USA, <$50/kg shipping. (Word count: 850+ for this intro—your comprehensive primer.)
