On the wet basis the value is the ratio of the weight of water to the total weight of the solution (1 / 5 = 20% in the example), so the moisture content is always below 100% (in the previous examples the moisture content was specified on this "moisture content wet basis"). For the moisture content dry basis the ratio of the weight of the water ...
An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
If the measured response is binary, the assay is quantal; if not, it is quantitative. [3] A bioassay may be used to detect biological hazards or to give an assessment of the quality of a mixture. [4] A bioassay is often used to monitor water quality as well as wastewater discharges and its impact on the surroundings. [5]
Dextrose equivalent (DE) is a measure of the amount of reducing sugars present in a sugar product, expressed as a percentage on a dry basis relative to dextrose. The dextrose equivalent gives an indication of the average degree of polymerisation (DP) for starch sugars. As a rule of thumb, DE × DP = 120.
C 0 t analysis, a technique based on the principles of DNA reassociation kinetics, is a biochemical technique that measures how much repetitive DNA is in a DNA sample such as a genome. [1]
Dried blood spot: gives high quality DNA and RNA Fingerstick: stores easily for years at room temperature organ tissue gives high quality DNA, RNA, Mitochondrial DNA, and source of disease Biopsy: many uses shared with blood; also suitable for proteomic analysis; may be difficult to obtain Plasma: limited DNA and RNA content Blood plasma ...
The Bradford protein assay (also known as the Coomassie protein assay) was developed by Marion M. Bradford in 1976. [1] It is a quick and accurate [2] spectroscopic analytical procedure used to measure the concentration of protein in a solution. The reaction is dependent on the amino acid composition of the measured proteins.
The purpose of this technique is to analyze the activity of a gene transcription promoter (in terms of expression of a so-called reporter gene under the regulatory control of that promoter) either in a quantitative manner, involving some measure of activity, or qualitatively (on versus off) through visualization of its activity in different cells, tissues, or organs.
