متن کاملMethod for recovering viruses from river water solids.
Small numbers of virions (poliovirus 1) that had been adsorbed to river water solids were eluted by mixing the solids for 30 min with a 10% solution of beef extract that contained sufficient Na2HPO4 to bring the molarity of the salt to 0.05 and sufficient citric acid to bring the pH to 7. The virions were recovered by inoculating the beef extract onto cell cultures. With this method, 39 to 63% ...
متن کاملA REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA
Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...
متن کاملIdentification of Cryptosporidium oocysts in river water.
Water samples were collected from four rivers in Washington State and two rivers in California and examined for the presence of Cryptosporidium oocysts. Oocyst-sized particles were concentrated from 20-liter samples of water by membrane filtration, centrifugation, and differential sedimentation. The particle concentrate was then deposited on a 25-mm-diameter membrane filter for oocyst identific...
