Abstract
The impetus to develop non-viral gene delivery vectors has led to examination of synthetic polycationic polymers as plasmid DNA (pDNA) condensing agents. Previous reports have highlighted superiority (up to x 10-fold) in the in-vitro transfection of pDNA complexes formed by poly-(L)-ornithine (PLO) compared to those formed with poly-(L)-lysine (PLL). The apparent basis for this consistent superiority of PLO complexes remains to be established. This comparative study investigates whether physico chemical differences in the supramolecular properties of polycation:pDNA complexes provide a basis for their observed differential gene transfection. Specifically, particle size distribution and zeta potential of the above complexes formulated over a wide range of polycation:pDNA ratios were found to be consistent with a condensed (150-200 nm) cationic ( + 30-40 mV) system but not influenced by the type of cationic polymer used. A spectrofluorimetric EtBr exclusion assay showed that polycation:pDNA complexes display different pDNA condensation behaviour, with PLO able to condense pDNA at a lower polycation mass compared to both polylysine isomers, and form complexes that were more resistant to disruption following challenge with anionic counter species, i.e. poly-(L)-aspartic acid and the glycosaminoglycan molecule. heparin. We conclude that particle size and surface potential as gross supramolecular properties of these complexes do not represent, at least in a non-biological system, the basis for the differential transfection behaviour observed between these condensing polymers. However, differences in the ability of the polylysine and polyornithine polymers to interact with pDNA and to stabilise the polymer-pDNA assembly could have profound effects upon the cellular and sub-cellular biological processing of pDNA molecules and contribute to the disparity in cell transfection efficiency observed between these complexes.

Abstract
The occurrence of high concentrations of ATP in certain cell organelles prompted us to study the self-association of ATP via the concentration dependence of the 1H-NMR chemical shifts for H2, H8 and H1' in D2O at pD 8.4 (25 degrees C) in the range 0.0025-0.4 M in the presence and absence of poly(alpha, L-lysine), where [Lys units] was 0.4 M. The experiment in the presence of poly(Lys) was repeated at pD 12.1. At pD 8.4, the poly(amino acid) is protonated, i.e. poly(H.Lys)n+, whereas at pD 12.1 only approximately 10% of the epsilon-amino groups are positively charged. The results in all three systems are consistent with the isodesmic model of indefinite non-cooperative stacking. The stacking tendency follows the series: ATP4- (K = 1.3 M-1; pD 8.4) < ATP4-/poly(H.Lys)n+ (K = 11.5 M-1; pD 8.4) > ATP4-/90% poly(Lys)/10% poly(H.Lys)n+ (K = 3.1 M-1; pD 12.1). It is evident that poly(H.Lys)n+ assists the association of ATP by a factor of approximately 10, and it is suggested that, via its positively charged epsilon-ammonium groups, poly(H.Lys)n+ acts as a matrix by aligning ATP4- ions via ionic interactions with the negatively charged phosphate residues. The intragranular concentrations of various constituents of several storage or secretory cell organelles, as reported in the literature, are tabulated. The chromaffin granules of the adrenal medulla and the dense granules of blood platelets contain particularly high concentrations of nucleotides ([ATP] is approximately 0.14 M in the chromaffin granules and 0.5 M in the dense granules of rabbit blood platelets) and amines, such as epinephrine or 5-hydroxytryptamine. These granules, and probably also the storage vesicles of certain neurons (which seem to have a similar composition), appear, if the total concentrations of the various solutes are considered, to be osmotically unstable, which means that the intragranular solutes must be associated. This aggregation is discussed, especially with regard to the nucleotides.

Abstract
The complexes of synthetic polymer ligands, i.e. poly-L-lysine, poly-4-vinyl-pyridine, poly-N-vinyl-2-methylimidazole and the higher branched polyethyleneimine, with ferri- or ferro-protoporphyrin IX were studied from the standpoint of polymer ligand effects by comparison with those of their monomeric model ligand complexes and poly-gamma-benzyl-L-glutamate containing an imidazole nucleus at the chain end. The coordination numbers and formation constants were determined optically and their structures were also estimated. The coordination number of a poly-L-lysine complex was two, but those of other polymer ligand complexes were one. One of the polymer effects, which was indicated by the large formation constants of the polymer complexes, was caused by the increment of the local ligand concentration around the polymer chain. Another was caused by the conformational effect of an alpha-helical structure in the poly-L-lysine complexes. The interaction of a poly-L-lysine-heme complex with molecular oxygen was also studied. An observed pseudo-allosteric phenomenon may be due to the specific structure of a poly-L-lysine complex which is different from those of other polymer ligand complexes.
