Human immunodeficiency virus type 1 (HIV-1) pol mutations are responsible for HIV-1 resistance to current antiretroviral drugs. HIV-1 RNA extraction with QIAamp HCV kit spin columns (Qiagen, Chatsworth, Calif.) followed by reverse transcription-PCR successfully recovered a 1,008-bp pol fragment from the plasma of 31 of 34 HIV-1-infected patients that was suitable for sequencing and recombinant-...
A large quantity of high quality RNA is often required in the analysis of gene expression. However, RNA extraction from samples taken from woody plants is generally complex, and represents the main limitation to study gene expression, particularly in refractory species like conifers. Standard RNA extraction protocols are available but they are highly time consuming, and not adapted to large sca...
Nucleic acid extraction is an attractive alternative to labor-intensive manual methods. In this report, a few methods of total RNA Extraction from Edible mushroom (Agaricus bisporus) compared. This methods consist AGPC(Acid Guanidinium-Phenol-Chloroform), The method according by Lithium chloride and RNx total RNA isolation Kit (CinnaGen). Best method selected for the preparation of high quality...
The emergence of a novel coronavirus (CoV) as the cause of severe acute respiratory syndrome (SARS) catalyzed the development of rapid diagnostic tests. Stool samples have been shown to be appropriate for diagnostic testing for SARS CoV, although it has been recognized to be a heterogeneous and difficult sample that contains amplification inhibitors. Limited information on the efficiency of ext...
We demonstrate the application of a rapid pre-concentration protocol and magnetic bead-based RNA extraction method for detection SARS-CoV-2 from raw wastewater without need extensive sample treatment.
Gastric tissue biopsy and gene expression analysis are important tools for disease diagnosis and study of the physiology of the equine stomach. However, RNA extraction from gastric biopsy samples is a complex procedure because the samples contain low quantities of RNA and are contaminated with mucous protein and bacterial flora. The objectives of these studies were to compare the performance of...
