Low molecular weight dextrans stabilize nonviral vectors during lyophilization at low osmolalities: concentrating suspensions by rehydration to reduced volumes.

Journal of Pharmacy and Science, 2005
Stabilization of nonviral vectors during freezing and drying requires formulation with protective excipients such that transfection rates and physical characteristics are maintained upon reconstitution. While many studies have demonstrated the ability of

Effect of crowding by dextrans and Ficolls on the rate of alkaline phosphatase-catalyzed hydrolysis: a size-dependent investigation.

Biopolymers, 2006
The cell cytosol is crowded with macromolecules such as proteins, nucleic acids, and membranes. The consequences of such crowding remain unclear. How is the rate of a typical enzymatic reaction, involving a freely diffusing enzyme and substrate, affected

Regional small-intestinal permeability in vitro to different-sized dextrans and proteins in the rat.

Scandinavian Journal of Gastroenterology, 1993
Molecular weight-dependent passage over different regions of the rat small intestine, using different-sized proteins/peptides and fluorescein isothiocyanate-dextrans in the 1- to 70-kDa range, was studied in vitro in modified Ussing chambers. The mucosal

The Effect of DEAE Dextran, Dextran Sulfate and Dextran on Porcine Mixed Lymphocyte Reaction

Zentralblatt für Veterinärmedizin Reihe B, 2010
Summary The polycation DD moderately stimulated lymph node lymphocytes from pigs and considerably enhanced MLR. The latter effect was especially marked when the reaction was in the descending phase. The MLR was dependent on cell number, and there was a strong correlation between optimal effective DD dose and cell number.

Studies on dextran and dextran derivatives. I. Properties of native dextran in different solvents

Biopolymers, 1964
AbstractLight‐scattering, sedimentation, viscosity, and reducing power measurements have been carried out on a sample of native dextran from Leuconostoc mesenteriodes B‐512. The results are discussed in relation to the structure, polydispersity, and branching of the polysaccharide.

Polylactide-Grafted Dextrans: Synthesis and Properties at Interfaces and in Solution

, 2004
A large variety of amphiphilic polylactide-grafted dextrans has been synthesized with controlled architecture through a three-step procedure:  partial protection of the dextran hydroxyl groups by silylation; ring-opening polymerization of D,L-lactide ...

Carboxymethyl benzylamide sulfonate dextrans (CMDBS), a family of biospecific polymers endowed with numerous biological properties: a review.

Journal of Biomedical Materials Research, 1999
The functionalized dextrans termed carboxymethyl benzylamide sulfonate dextran (CMDBS) represent a family encompassing a wide range of polymers. These soluble macromolecular compounds, which are substituted with specific chemical functional groups, are ...
