Development of an ammonium sulfate DNA extraction

DNA extraction from microdissected cells has become essential for handling clinical specimens with advances in molecular pathology. Conventional methods have limitations for extracting amplifiable DNA from specimens containing a small number of cells. We developed an ammonium sulfate DNA extraction

Development of an ammonium sulfate DNA extraction

2013-4-17  Briefly, 50 μL of ammonium sulfate DNA extraction buffer solution (16 mM (NH 4) 2 SO 4, 50 mM Tris-HCl pH 8.5, 1 mM EDTA pH 8.0, and 0.5% Tween-20) was added to the dissected cells or tissues in a 0.2 mL PCR tube, and Proteinase K (Takara Bio. Inc., Shiga, Japan) was added to a final concentration of 200 µg/mL and then

Extraction of rat skin DNA with sodium dodecyl sulfate ...

Before extraction of DNA was resumed, the skin was thawed to room temperature. Samples of approximately 100 mg of skin were cut from the larger piece. Each sample of skin was placed into a test tube containing 1 ml of 0.9% NaCl and 0.2 ml of sodium dodecyl sulfate (57o in 45% ethanol). The tube was then shaken vigorously for 1 min in a ...

Protocol: DNA Extraction Method

As a biological engineer, I stitch pieces of genes into circular pieces of DNA (plasmids) to create new cellular pathways. Though many of the protocols I use in the lab take a long time and have a high rate of failure, DNA extraction is simple, works 99% of the time, and takes less than 30 minutes. Creating a new plasmid is an iterative process ...

A phenol/chloroform-free method to extract nucleic acids ...

2019-6-5  Woody tropical plants contain high levels of complex organic compounds that inhibit the chemical procedures needed to extract RNA or DNA, thus compromising downstream applications such as RNA sequencing and analysis of gene expression. To overcome this issue, researchers must use extraction protocols using CTAB/PVP buffer instead of commercially available DNA/RNA extraction kits.

A simple and efficient method for extraction of Taq DNA ...

2015-9-1  Thermostable DNA polymerase (Taq Pol Ι) from Thermus aquaticus has been widely used in PCR, which was usually extracted with Pluthero's method. The method used ammonium sulfate to precipitate the enzyme, and it saved effort and money but not time. Moreover, we found that 30–40% activity of Taq Pol I was lost at the ammonium sulfate ...
