In vitro Labeling of Neural Stem Cells with Poly-L-Lysine Coated Super Paramagnetic Nanoparticles for Green Fluorescent Protein Transfection
Background: The magnetic nanoparticle-based transfection method is a relatively new technique for delivery of functional genes to target tissues. We aimed to evaluate the transfection efficiency of rat neural stem cell (NSC) using poly-L-lysine hydrobromide (PLL)-coated super paramagnetic iron oxide nanoparticles (SPION). Methods: The SPION was prepared and coated with PLL as transfection agent...
متن کاملInhibition of tumor growth in mice by endostatin derived from abdominal transplanted encapsulated cells.
Endostatin, a C-terminal fragment of collagen 18a, inhibits the growth of established tumors and metastases in vivo by inhibiting angiogenesis. However, the purification procedures required for large-scale production and the attendant cost of these processes, together with the low effectiveness in clinical tests, suggest that alternative delivery methods might be required for efficient therapeu...

Nanofibers canbe used to deliver drugs and are capable of controlled release for a continued periodof time. Poly (Lactic Acid) (PLA) is the lastly interesting employed synthetic polymer in biomedical application owing to its well categorized biodegradable prop...
متن کاملStudy of the inhibitory effects of N-heterocycles, magnesium oxide nanoparticles, nisin and poly-L-lysine on Enterobacter aerogenes (hospital pathogen)
Background: Enterobacter aerogenesis one of the causes of hospital-acquired infections, which its standard strains quickly become resistant to the antibiotics. The discovery of new inhibitory agents against this pathogen is constantly expanding. In this study, the inhibitory effects of several synthetic chemical compounds including magnesium oxide nanoparticles and thiazole, imidazolidine and t...
متن کاملAffinity partitioning. A method for purification of proteins using specific polymer-ligands in aqueous polymer two-phase systems.
We describe a method, called affinity partitioning, for the purification of proteins containing specific ligand binding receptor sites. This method adds specificity to the procedures for protein purification with aqueous polymer two-phase systems by introduction of a polymer derivative, coupled to an appropriate ligand. The addition of a polymer-ligand that partitions predominantly into one pha...
