objective: dna vaccines have been widely used to develop immunity against various pathogens including parasites and viruses. the potential of dna vaccine to induce an effective immune response is related to the expression levels of the encoded protein in eukaryotic cells. therefore, optimization of plasmid dna delivery system is a major concern in protein expression in order to make an efficien...

Objective(s): PEI based nanoparticle (NP) due to dual capabilities of proton sponge and DNA binding is known as powerful tool for nucleic acid delivery to cells. However, serious cytotoxicity and complicated conditions, which govern NPs properties and its interactions with cells practically, hindered achievement to high transfection efficiency. Here, we have tried to optimize the properties of ...

epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant dna techniques. the aim of this study was to sub-clone the peroxisomal protein (pep) cdna into a mammalian expression vector leading to the formation of a  chimeric pep-cdna containing the flag epitope. the flag-pep recombinant cdna was construc...

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...

Alteration of adipocyte function contributes to the pathogenesis metabolic diseases including Type 2 diabetes and insulin resistance. This highlights need better understand molecular mechanism involved in dysfunction develop new therapies against obesity-related diseases. Modulating expression proteins micro-RNAs adipocytes remains highly challenging. paper describes a protocol differentiate mu...

Background: Baculovirus expression system is one of the most attractive and powerful eukaryotic expression systems for the production of recombinant proteins. The presence of a biomarker is required to monitor transfection efficiency or protein expression levels in insect cells. Methods: The aim of this study was to construct a baculovirus expression vector encoding a copepod super green fluore...

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...
