Western Blot AnalysisThe target protein is extracted from the cell or tissue sample and then separated by SDS-PAGE electrophoresis. Then, the separated proteins are transferred to a membrane and immunoblotted with ubiquitin-specific antibodies. ...
This includes sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and two-dimensional gel electrophoresis (2-DE).Features: High sensitivity and resolution, good separation effect, it's mainly used to determine the presence of specific proteins in the sample or to determine the types of proteins in the sample; but the operation is relatively ...
To carry out effective proteomic analysis, the preparation of the sample must meet certain requirements. Here are some common proteomics sequencing sample requirements. Purity of the Sample The purity of the protein in the sample should be as high as possible to reduce interference from non-target proteins. It may be necessary to ...
Winkler Titration: This traditional method involves adding reagents to a water sample to precipitate oxygen, which is then titrated to determine its concentration. ...
There will be differences observed for some solvent combinations and for some samples. Remember that there are at least four reasonable ways to prepare 50:50 Methanol: Water. ...
Based on the observed data of monthly precipitation and runoff from 1960 to 2011 in the catchment controlled by the Sandaohezi hydrological station, the double mass curve of precipitation-runoff and Kolmogorov–Smirnov dual sample test were applied to divide the years 1960–2011 into four periods: 1960–1979, 1980–1991, 1992–1999 and 2000–2011. ...
The greater the purged volume the longer time to achieve a sample and the more questionable the representative quality of the sample. ...
Viruses were recovered from the samples using a glass wool adsorption-elution method and then further concentrated using polyethylene glycol/sodium chloride precipitation. After automated nucleic acid extraction, samples were analysed for HAV by real-time reverse-transcriptase polymerase chain reaction. ...
Furthermore, we conducted an initial investigation on how well retention soil filters reduce certain micropollutants on large-scale plants. There was little precipitation during the 1-year sampling phase, which led to fewer samples than expected. ...
Biweekly during the rice‐growing season, tissues of rice plants, corresponding soil, precipitation, and irrigation water samples were collected. The sampling data support the following: (1) the atmosphere is the principal source of IHg to the aboveground parts of the rice plant; (2) both the atmosphere and soil contribute to IHg content in ...
In order to assess the fate of salmonellae in supposedly pristine environments, water and natural biofilm samples along with snails (Tarebia granifera) and crayfish (Procambarus clarkia) were collected before and up to 7 days following four precipitation events from sites within the headwater springs of Spring Lake, San Marcos, TX. ...
The kinetic curve of hydrogen generation of some hematite morphology samples was examined by redox cycle and the hydrogen fuel was formed by oxidation with water vapour. Although the nanorod morphology of hematite samples was damaged during redox cycles, the samples demonstrated high activity for hydrogen generation in comparison with ...
Flue gases were simultaneously sampled at the selective catalytic reduction (SCR) inlet, the SCR outlet, the electrostatic precipitator (ESP) outlet, and the stack. Samplings of coal, lime, bottom ash/slag, fly ash, and gypsum slurry were also conducted. ...
Sulfate determination with the Ca ISE PrincipleThe basic principle for the determi¬nation of sulfate using the calcium ISE (Ca ISE) is really very simple. Sulfate present in the sample is pre¬cipitated with an excess of barium chloride at pH 4. The barium still present in the solution after com¬plete precipitation of the sulfate is then back titrated at pH 10 ...
This paper describes a comparative evaluation of collectors for metal removal by precipitation/flotation in samples of wastewaters from an electroplating industry. Precipitation/flotation was found to be successful over a great range of pH (3-12). The toxic metal ions lead (II), nickel (II), tin (II), iron (II) and aluminium (III) were ...
The sequentially collected samples are analysed for major ions concentrations and pH estimations. The pH values for all samples vary from 5.1-7.6. In general, the concentration of all rainwater samples decrease with time. Furthermore, it is estimated that the average Ca2+) (1943.0 µeql-1) and SO42- (887.3 µeql-1) concentrations are ...
