1,700+ technical articles by Aladdin Scientific's scientists on reagent selection, reaction mechanisms, assay design and formulation. New every week.
Core Purpose: Ensure safety. It is a mandatory technical document for chemicals classified as hazardous (e.g., flammable, toxic, corrosive). It conveys the hazard information of chemicals, guides staff in safe operation, storage, emergency handling (such as leakage and fire), and disposal of ...
Serine proteases are widespread inside and outside cells and play key roles in proteolysis, signal transduction, and apoptosis. In protein extraction and purification, endogenous or exogenous serine proteases can rapidly cleave target proteins if left unchecked, severely compromising sample ...
In protein biochemistry, salts appear in nearly every recipe. While their role in buffering is familiar, salts themselves can serve as practical tools for protein separation and purification. By tuning salt species and concentration, one can markedly alter protein solubility to achieve selective ...
Glutathione (GSH) is a tripeptide composed of glutamate, cysteine, and glycine. It is one of the most important small-molecule reductants in cells, helping maintain redox balance, scavenge reactive oxygen species, and protect biomacromolecules from oxidative damage. Glutathione S-transferases ...
In prokaryotic hosts such as E. coli, formation of inclusion bodies is common during recombinant protein expression. For many insoluble or structurally complex proteins—especially human proteins rich in disulfide bonds or intrinsically disordered regions—inclusion bodies are often nearly ...
In His-tag affinity purification, Ni²⁺-NTA/IDA resins gradually lose performance due to fouled coordination sites, metal loss, and pore clogging, manifested as reduced binding capacity, increased nonspecific adsorption, and elution tailing. Periodic “strip–clean–recharge” maintenance ...
Ni²⁺–agarose beads (typically Ni-NTA/Ni-IDA) capture recombinant proteins via coordination between multiple immobilized chelation sites and the imidazole rings of His tags.
Ni-agarose beads (commonly Ni-NTA or Ni-IDA) used for His-tag protein purification typically appear blue or blue-green.
Maintaining a stable extracellular pH minimizes nonspecific fluctuations in metabolism and signaling.
