A dextran sulphate gel column removed anti-double-stranded DNA antibodies (anti-dsDNA) selectively, efficiently, and safely from the circulation of a patient with systemic lupus erythematosus (SLE). The mechanism of the removal is thought to be due to cross reactivity of anti-dsDNA with dextran sulphate, which has negatively charged units. Selective removal of anti-dsDNA is expected to contribu...

The renal clearance of [3H]dextran sulphate by the isolated perfused rat kidney was associated with desulphation of the molecule, as demonstrated by ion-exchange and affinity chromatography of material resident in both glomeruli and urine samples. This process also occurred in vivo. The molecular size distribution of glomerular dextran sulphate in the perfused kidney was indistinguishable from ...

The natural and semisynthetic carbohydrates scleroglucan, locust bean gum, tamarind gum (glyloid) and its three sulphate derivatives (GP4311, GP4327 and GP4324), glycogen and its two sulphate derivatives (GP4427 and GP4435), alginic acid and dextran sulphate, were investigated for their inhibitory effect on rubella virus (RV) infection of Vero cells. The neutral polymer scleroglucan and two hig...

This review deals with the layer-by-layer (LbL) assembly of polyelectrolyte multilayers of biopolymers, polypeptides (i.e., poly-l-lysine/poly-l-glutamic acid) and polysaccharides (i.e., chitosan/dextran sulphate/sodium alginate), onto thermo- and/or pH-responsive micro- and nano-gels such as those based on synthetic poly(N-isopropylacrylamide) (PNIPAM) and poly(acrylic acid) (PAA) or biodegrad...

This paper describes a simple purification procedure for protease nexin, a serine proteinase inhibitor secreted by cultured human fibroblasts that regulates proteinase activity at and near the cell surface. The first step in the procedure takes advantage of the high-affinity binding of protease nexin to dextran sulphate-Sepharose. This step eliminates the need for prior concentration of the ser...
