Reversed-phase chromatography (C18/C8) excels at separating neutral analytes with clear hydrophobicity differences. But when a sample contains many charged or highly polar components (e.g., amine salts, quaternary ammonium salts, carboxylates, phosphates, nucleotides/oligonucleotides), these ...
A solid oxide fuel cell (SOFC) is an electrochemical device that converts a fuel’s chemical energy directly into electricity. Instead of relying on the traditional chain of “combustion → heat → mechanical work → power generation,” it uses electrochemical reactions to drive electrons ...
Under denaturing conditions such as 6–8 M urea, proteins unfold and expose charged residues, enabling ion-exchange chromatography (IEX) to separate species by differences in net charge while maintaining solubility.
Soluble sugars are important physiologically active substances in plants. They are not only the major products of photosynthesis and core carriers of energy metabolism, but also participate in key processes such as cellular structural construction, signal transduction, and stress-response ...
Rare earths are a group of elements. The most common definition includes the 15 lanthanides (La–Lu) plus yttrium (Y) and scandium (Sc).
Many people feel confused the first time they encounter “NO donors”: isn’t NO simply a gas—nitric oxide (Nitric Oxide, NO)? How can a gas be “purchased as a reagent,” and why are there so many categories?
Epigenetic regulation at the chromatin level is a key link between genomic sequence and cellular phenotype. With the rapid development of high-throughput sequencing, a series of methods for profiling protein–DNA interactions and chromatin accessibility have emerged.
The core of protein chromatographic purification is to maintain the target protein in a conformationally stable state under operating conditions, while enabling controllable interactions and reproducible separation behavior. Buffers do not only define pH; through temperature coefficients, ionic ...
Phthalocyanines (Pc, phthalocyanine) are a class of macrocyclic, highly conjugated molecules. You can think of Pc as an exceptionally stable “conjugated macrocycle disk”: the periphery can be decorated with different substituents, and a metal can be inserted at the center to form a metal ...
