This assay is one of the fastest assays performed on proteins. [12] The total time it takes to set up and complete the assay is under 30 minutes. [13] The entire experiment is done at room temperature. The Bradford protein assay can measure protein quantities as little as 1 to 20 μg. [14] It is an extremely sensitive technique.

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.
[3]: 21–119 Following this testing the sample at 420 nm for specific interaction with ONPG and at 595 for a Bradford Assay the amount of purification can be assessed quantitatively. [ 3 ] : 21–119 In addition to this spectrophotometry can be used in tandem with other techniques such as SDS-Page electrophoresis in order to purify and isolate ...
Bradford was born October 28, 1946, in Rome, Georgia, US, and received his B.A. from Shorter College there in 1967. [1] In 1971 he married Janet Holliday. [1] [8] He obtained his Ph.D. in biochemistry from the University of Georgia in 1975, and his use of the Coomassie Brilliant Blue G-250 dye to detect proteins, which became known as the Bradford assay, was patented in 1976.
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 ...
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.

A mobility shift assay is electrophoretic separation of a protein–DNA or protein–RNA mixture on a polyacrylamide or agarose gel for a short period (about 1.5-2 hr for a 15- to 20-cm gel). [4] The speed at which different molecules (and combinations thereof) move through the gel is determined by their size and charge, and to a lesser extent ...
