BCA protein assay in a 96 well plate. The bicinchoninic acid assay (BCA assay), also known as the Smith assay, after its inventor, Paul K. Smith at the Pierce Chemical Company, [1] now part of Thermo Fisher Scientific, is a biochemical assay for determining the total concentration of protein in a solution (0.5 μg/mL to 1.5 mg/mL), similar to Lowry protein assay, Bradford protein assay or ...
Protein detection can monitor soybean protein labeling system in processed foods to protect consumers in a reliable way. [8] The labeling for soybean protein declaimed by protein detection has indicated to be the most important solution. [8] Detailed labeling description for the soybean ingredients in refined foods is required to protect the ...
Whereas the concept of water activity is widely known and utilized in the applied biosciences, its complement—the protein activity which quantitates protein–protein interactions—is much less familiar to bioscientists as it is more difficult to determine in dilute solutions of proteins; protein activity is also much harder to determine for ...
Example conversion factors, known as N factors, for foods range from 6.38 for dairy and 6.25 for meat, eggs, maize (corn) and sorghum to 5.83 for most grains; 5.95 for rice, 5.70 for wheat flour, and 5.46 for peanuts. [7] In practice, 6.25 is used for almost all food and feed regardless of applicability.
Austin, Texas. The Lone Star State's capital gets plenty of coverage for being one of the best food truck park cities in the nation. Among the more popular is The Picnic, which is located near ...
After initial purification, protein solutions may need to be concentrated to increase the protein's concentration for downstream applications. This can be achieved through various methods, including ultrafiltration, which uses semi-permeable membranes to separate proteins from smaller molecules and salts, and lyophilization (freeze-drying ...
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.
