Ruby spectra R1, R2 lines. The ruby fluorescence pressure scale is an optical method to measure pressure within a sample chamber of a diamond anvil cell apparatus. [1] Since it is an optical method, which fully make use of the transparency of diamond anvils and only requires an access to a small scale laser generator, it has become the most prevalent pressure gauge method in high pressure ...
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.
The density of RAD tags in a genome depends on the restriction enzyme used during the isolation process. [5] There are other restriction site marker techniques, like RFLP or amplified fragment length polymorphism (AFLP), which use fragment length polymorphism caused by different restriction sites, for the distinction of genetic polymorphism.
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.
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.
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 ...
However, recent studies using fluorescent labeled Rad51 [11] have indicated that Rad51 fragments elongate via multiple nucleation events followed by growth, with the total fragment terminating when it reaches about 2 μm in length. However, disassociation of Rad51 from dsDNA is slow and incomplete, suggesting that there is a separate mechanism ...
The lanthanide contraction is the greater-than-expected decrease in atomic radii and ionic radii of the elements in the lanthanide series, from left to right. It is caused by the poor shielding effect of nuclear charge by the 4f electrons along with the expected periodic trend of increasing electronegativity and nuclear charge on moving from left to right.
