Small interfering RNA; principles, applications and challenges--

Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...

Isolation and detection of small RNA molecules

The article describes in detail methodical procedures for isolation of small RNA molecules, their electrophoresis, northern blotting and finally detection by hybridization with radioactively labeled riboprobes. The presented protocols were successfully introduced and used in our laboratory.

Optimization of RNA Extraction from Rat Pancreatic Tissue

Background: Optimized RNA extraction from tissues and cell lines consists of four main stages regardless of the method of extraction: 1) homogenizing, 2) effective denaturation of proteins from RNA, 3) inactivation of ribonuclease, and 4) removal of any DNA, protein, and carbohydrate contamination. Isolation of undamaged intact RNA is challenging when the related tissue contains high levels of ...

Magnetic nanoparticles: a promising component in RNA extraction process

Magnetic nanoparticles separation technology is a method for quick and easy extraction biomolecules such as proteins, DNA and RNA. The present work describes total RNA isolation procedure from transformed rose petals in our laboratory using magnetic nanoparticles as a solid phase absorbant. Petals are the main sources of secondary metabolites, i.e. carotenoids, anthocyanins, flavonoids and phen...
