What is Diisopropyl Phthalate?

<P>  <STRONG><A href="http://www.chemical-raw-material.com/products/Materials-chemistry/Diisopropyl-Phthalate/">Diisopropyl Phthalate</A></STRONG> is a phthalate used as a plasticizer. Diisopropyl Phthalate is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid.</P>

Development of Dioctadecyldimethylammonium Monoolein Liposomes for Gene Delivery

  The electrostatic abhorrence amid the phosphodiester anionic accuse of nucleic acids (NA) and the negatively-charged headgroups of corpuscle film phospholipids hinders naked NA to charge the claret membrane. Additionally, nucleases present in the beef and in biological fluids enzymatically abase NA, attached their biofunctionality. Although abounding another methods accept been developed to bear NA to cells, factors such as versatility, account and ability accept beat their broadcast use in gene therapy.


pH determination by pyranine: medium-related artifacts and their correction

  Pyranine is a water-soluble, membrane-impermeable fluorophore accepting beaming action and discharge spectra that are awful abased on average pH. This aggregate makes it one of the a lot of frequently acclimated pH-sensitive beaming probes to adviser pH and pH changes in biochemical and biophysical research. The pK(a) of this delving is appear to be about 7.3, but several studies (including the accepted one) accept credible that this amount varies with average composition.
