Bathophenanthroline is a nitrogen-containing organic ligand that can form stable complexes with transition metal ions such as Ru 2+. In proteomics, Bathophenanthroline is often used for in-gel protein staining. The negatively charged sulfonic acid groups of Bathophenanthroline interact electrostatically with the positively charged amino acid residues of proteins, thereby achieving specific binding to proteins and enhancing the fluorescent signal of detection. Bathophenanthroline can be used for protein separation and detection in SDS-PAGE gels in the field of proteomics, as well as other fluorescence studies[1]. Ex/Em=532 nm/610 nm[1].

Sodium polyphosphate, crystal,+200 mesh, 96% is an inorganic polyphosphate that also serves as a stabilizer, dispersant, chelating agent, and coacervate-forming agent. Sodium polyphosphate provides electrostatic stabilization for mineral and material suspensions, but its dispersing efficacy decreases under acidic pH, high temperature, high calcium concentration, or a combination of these conditions. Sodium polyphosphate can chelate alkaline earth metals, reduce solution pH, and alter the rate of pH decline at a divalent cation/phosphorus molar ratio of 0.18. Sodium polyphosphate forms coacervates with smaller divalent cations and precipitates with larger divalent cations, where the functional requirements of cations depend on polyphosphate concentration, average degree of polymerization, and cation type .

Synonyms: Sodium stearyl sulfate
Sodium octadecyl sulfate (Sodium stearyl sulfate) is a long-chain alkyl sodium sulfate that functions as an emulsifier, crosslinking agent, and regulator. Sodium octadecyl sulfate has high safety, with a LD50 greater than 3.00 Gm./Kg for both intraperitoneal injection in mice and oral administration in rats. Sodium octadecyl sulfate enhances continuous contraction of the gastrocnemius muscle in frogs and boosts intestinal smooth muscle activity in albino rats. However, Sodium octadecyl sulfate exerts no significant effect on isolated tortoise myocardium and does not alter the conduction function of frog sciatic nerves. Sodium octadecyl sulfate can also be used to coat the surface of starch aggregates, promote crosslinking and increase aggregate size through hydrophobic and electrostatic interactions, and further form a coexistent B-V type crystalline structure with acid-hydrolyzed gelatinized starch, thereby effectively modifying the structure and surface properties of high-starch systems .
