lipofectamine ltx is a cationic based transfection reagent that offers high levels of different transgenes expression in a huge number of cell types in vitro utilizing an easy and rapid protocol. the level of transgenes expression depend on some experimental variables containing cell density, lipofectamine and dna concentrations, lipofectamine -dna complexing time, and the presence or absence o...
The solid-phase synthesis of a library of arginine-containing lipid transfection agents on high-loading beads is described. The transfection activity of the cationic lipids was determined using compound cleaved from single beads (single-bead screening) and showed, in some cases, comparable or higher DNA transfection activities as compared to commercially available reagents. Lipids with one argi...
objective(s): carbon nanotube (cnt) has been widely applied at molecular and cellular levels due to its exceptional properties. studies based on conjugation of cnts with biological molecules indicated that biological activity is preserved. polyethylenimine (pei) is explored in designing novel gene delivery vectors due to its ability to condense plasmid dna through electrostatic attraction. in t...
The effect of tripeptide, Arg-Gly-Asp (RGD), on the transfection activity of Bacillus phage M2 DNA was examined. The transfection activity decreased when M2 DNA was preincubated with RGD before it was added to competent cells.
total protein and dna extracted from histologically diagnosed normal nonmalignant and esophageal tumor tissues were used for analysis of polypeptides pattern by two-dimensional gel electrophoresis and dna transforming activity in nih 3t3 cell transfection assay, respectively. in comparison to normal tissues, eight polypeptides underwent down-regulation or disappeared, while seven polypeptides w...
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...
establishment of a novel muscle cell line from wallago attu for in vitro study of pesticide toxicity
background fish cell lines are advantageous alternatives to mammalian cell lines for carrying out in vitro research. they are used extensively for the study of fish biology, physiology and toxicology, and more recently for germplasm conservation of important fish species. objectives the present study aims to establish and characterize a novel fish cell line from muscle tissue of wallago attu ca...
Survivin, an inhibitor of apoptosis protein is highly expressed in most cancers and considered as an attractive target for cancer antisense therapy. To vectorize antisense molecules, cationic nanoliposomes are generally used; however, their complexes are too instable, during shelf-life and upon exposure to blood components and extracellular matrix, to be used in-vivo. The present study a...
