Determination of polycyclic aromatic hydrocarbons in waters by ultrasound-assisted emulsification-microextraction and gas chromatography–mass spectrometry An ultrasound-assisted emulsification-microextraction (USAEME) procedure was developed for the extraction of US EPA 16 polycyclic aromatic hydrocarbons (PA......
A rapid and efficient procedure for purifying bacteriophage λ DNA is described. This small-scale purification involves isolation of bacteriophage particles on cesium chloride gradients. Using an Airfuge ultracentrifuge, the centrifugation step can be readily achieved in 90 minutes. The method allows a ...
This procedure, known as ultracentrifugation, can be applied for the separation of macromolecules from a solution, and the separation takes place differentiating macromolecules by their molecular weight [19]. For a homodisperse solute in ideal conditions, the relation between the molecular weight M, ...
The simple procedure, a continuous-step density gradient technique, was developed to selectively concentrate progressively motile sperm. The ejaculated semen was placed on 6.0 ml of 80% Percoll solution, and the density gradient was formed by mixing the semen and Percoll with an L-shaped rod for...

The method by which this volume was determined is described. The procedure itself has no measurable effect on viability or permeability of the cells and permits recovery of about 90% of the cells from the aqueous environment. With this method, it has been found that the intracellular water ...
4.2. The following modification of the density gradient procedure may sometimes be used even with angle rotors for initial concentration of a virus without pelleting at the bottom of the tube. A cushion of a few millilitres of dense sucrose is placed in the bottom of the tube, this being ...
