Simultaneous extraction from bacterioplankton of total RNA and DNA suitable for quantitative structure and function analyses.

The challenge of getting a high quality of RNA from oocyte for gene expression study

The extraction of intact RNA from oocyte is quite challenging and time-consuming. A standard protocol using commercial RNA extraction kit, yields a low quantity of RNA in oocytes. In the past, several attempts in getting RNA for gene expression study ended up with a few different modified methods. Extraction of high-quality RNA from oocyte is important before further downstream analyses such as...

Comparison study of three methods for genomic DNA extraction from fresh and herbarium leaf specimens of Achillea wilhelmsii C.Koch

DNA extraction from plant tissues often causes most problems. For example, unsuccessful removal secondary metabolites during extraction, such as phenolic compounds in aromatic and medicinal plants, cause to some mistakes in result of molecular experiments by using of the extracted DNA. Achillea wilhelmsii is a medicinal plant belong to Asteraceae family and native to Iran, there is little infor...

Isolation of high-quality RNA from a wide range of woody plants

Isolation of high-quality RNA is one of the most crucial methods in molecular biology. RNA extraction from woody plants has been problematic due to the presence of rigid and woody tissues, large amounts of polysaccharides, polyphenols and other secondary metabolites. Here we present a suitable protocol for RNA isolation from a wide range of woody plants that includes eight gymnosperms and four ...

Extraction of total RNA and DNA from bacterioplankton

Effect of Matrigel on Function and Morphology of Human Endometrial Epithelial Cell in vitro

The importance of extra cellular matrix (ECM) in development and function of different cells has been reported but little is known about its role in human endometrial epithelial cells. The aim of the present study was to examine effects of artificial ECM (Matrigel) and progesterone on the function and morphology of human endometrial epithelial cells in vitro. Methods: Endometrial samples were ...
