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.
A concentrated solution of metals is obtained by eluting the resin with a small volume of 2 M nitric acid, which protonates the iminodiacetate groups. Chelex resin is often used for DNA extraction in preparation for polymerase chain reaction by binding to cations including Mg 2+ , which is an essential cofactor for DNases .
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.
Turn on and adjust a spectrophotometer to a wavelength of 595 nm, and blank the spectrophotometer using 1.5 mL cuvettes or use a mobile smartphone camera (RGBradford method). [9] Wait 2 minutes and read the absorbance of each standard and sample at 595 nm. Plot the absorbance of the standards vs. their concentration.
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 ...

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.
[4] [5] The first clinical study of vosilasarm, a small (n=22) phase 1 study in women with metastatic breast cancer, was started in 2017 and completed in 2020, with results published in 2019, 2020, and 2022. [10] [3] [2] [17] [15] As of March 2023, vosilasarm is in phase 1/2 clinical trials for the treatment of breast cancer. [4] [18]
