Bio-Rad Laboratories, Inc. is an American developer and manufacturer of specialized technological products for the life science research and clinical diagnostics markets. The company was founded in 1952 in Berkeley, California , by husband and wife team David and Alice Schwartz , both graduates of the University of California, Berkeley.
Fast protein liquid chromatography (FPLC) is a form of liquid chromatography that is often used to analyze or purify mixtures of proteins. As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the mobile phase) and a porous solid (the stationary phase).
An example Gel documentation system, showing the results of gel electrophoresis on a connected monitor.. A gel doc, also known as a gel documentation system, gel image system or gel imager, refers to equipment widely used in molecular biology laboratories for the imaging and documentation of nucleic acid and protein suspended within polyacrylamide or agarose gels.
Since version 5, Unity has been offering its WebGL bundle compiled to JavaScript using a 2-stage language translator (C# to C++ and finally to JavaScript). [94] Unity was the default software development kit (SDK) used for Nintendo's Wii U video game console , with a free copy included by Nintendo with each Wii U developer license.
Chelex 100 is a chelating material from Bio-Rad [1] used to purify other compounds via ion exchange. It is noteworthy for its ability to bind transition metal ions. It is a styrene -divinylbenzene co-polymer containing iminodiacetic acid groups.
The instrument can also optionally be calibrated with a stock solution of a sample at a concentration known to have an absorbance of 2 or else vendor supplied standards, using the light absorption knob in the diagram shown at right. [3] After calibration, the user places a 1/2 inch test tube or cuvette containing the sample solution to be ...
For transistors, the current-gain–bandwidth product is known as the f T or transition frequency. [4] [5] It is calculated from the low-frequency (a few kilohertz) current gain under specified test conditions, and the cutoff frequency at which the current gain drops by 3 decibels (70% amplitude); the product of these two values can be thought of as the frequency at which the current gain ...
Shows the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) to 3,3',5,5'-tetramethylbenzidine diimine. The resulting one-electron oxidation product is a diimine-diamine complex, which causes the solution to take on a blue colour, [2] and this colour change can be read on a spectrophotometer at the wavelengths of 370 and 650 nm.
