Plasmid DNA was encapsulated within poly(d,l-lactic-co-glycolic acid) (PLGA) nanospheres by using polyethylene glycol (PEG) assisted solubilization technique of plasmid DNA in organic solvents. Plasmid DNA was solubilized in an organic solvent mixture composed of 80% methylene chloride and 20% DMSO by producing PEG/DNA nano-complexes having an average diameter less than 100 nm. DNA could be sol...
Fructose-1,6-bisphosphate aldolase from Drosophila melanogaster has been crystallized from polyethylene glycol 6000 by vapor diffusion technique against buffered polyethylene glycol solutions at 2-4 degrees C. The insect enzyme crystallizes in the orthorhombic system, heretofore unknown for aldolases. The crystals have the space group P212121 (a = 86.3 A, b = 115.7 A, and c = 151.4 A) and conta...
Up to 80% of the cost of vaccination programmes is due to the cold chain problem (that is, keeping vaccines cold). Inexpensive, biocompatible additives to slow down the degradation of virus particles would address the problem. Here we propose and characterize additives that, already at very low concentrations, improve the storage time of adenovirus type 5. Anionic gold nanoparticles (10-8-10-6 ...
