The primary purpose of a buffer is to control the pH of the solution. Buffers can also play secondary roles in a system, such as controlling ionic strength or solvating species, perhaps even affecting protein or nucleic acid structure or activity. Buffers are used to stabilize nucleic acids, ...
(Application) the product can be used for the preparation of buffer solution in biochemistry and molecular biology experiment, pharmaceutical intermediate, surfactant and curing accelerator, water-soluble polymer containing Tris structure unit as paint dispersant, formaldehyde adsorptio...
forcing a nucleic acid solution through a small hole in a nebulizer. The aerosolized sample with fragmented DNA is then collected. The level of fragmentation can be controlled by the compressed gas pressure and can also be affected...

Process liquid and buffer manufacturing for upstream and downstream bioprocessing requires weighing, dispensing, and hydrating (formulation) a wide range of chemicals to support all aspects of bioproduction unit operations. Process liquid manufacturing requires significant investments in dedicated cGMP space, ...
However, the significant fluorescence quenching of 1 was observed after adding 10 equiv. of Cu2+. In UV/vis experiment, upon addition of Cu2+ to the solution of 1, the absorption of 1 at ca. 250–350 nm increased remarkably, but other cations had no similar influence on the ...
