Dimethyl sulfoxide, meets analytical specification of Ch.P.
0 ImagesSynonyms: DMSO, meets analytical specification of Ch.P.Dimethyl sulfoxide (DMSO), meets analytical specification of Ch.P. is an aprotic solvent that dissolves polar and non-polar compounds, including water-insoluble therapeutic and toxic agents. Dimethyl sulfoxide (DMSO) has a strong affinity for water and can rapidly penetrate or enhance the penetration of other substances into biological membranes. Dimethyl sulfoxide also has potential free radical scavenging and anticholinesterase effects and may affect coagulation activity. Dimethyl sulfoxide also induces histamine release from mast cells but is thought to have low systemic toxicity. Dimethyl sulfoxide also exhibits antifreeze and antibacterial properties.
MCE provides Dimethyl sulfoxide that complies with the inspection standards (Ch.P) of Part 4 of the Chinese Pharmacopoeia (2020 Edition). Amicrobic, low endotoxin, can be used in various biochemical experiments such as drug dissolution.

Iron(II) chloride
0 ImagesSynonyms: FerroflocIron (II) chloride (Ferrofloc) is an active radical polymerization initiator, which is a transition metal chloride composed of Fe2+ and Cl− ions. The ion association constant logKFeCl2 of Iron (II) chloride is −0.89. In acidic aqueous solutions, Iron (II) chloride forms solvated Fe2++2Cl− ions as well as FeCl++Cl− ion pairs. Without the addition of aluminum compounds, Iron (II) chloride drives the living radical polymerization of methyl methacrylate by generating transient radical growing species through homolytic reversible cleavage of the carbon-halogen end groups of organic halide initiators.

Sodium bromide
0 ImagesSodium bromide (NSC 77384; Sanibrom 40) is a GABA-ergic system modulator that crosses the blood-brain barrier, and it effectively reduces and blocks epileptiform discharges. Sodium bromide exerts significant anticonvulsant effects by enhancing GABA-ergic inhibitory functions, such as increasing the amplitude of inhibitory postsynaptic currents and paired-pulse inhibition. Sodium bromide specifically enhances stimulation-induced extracellular alkalosis without affecting baseline pH or subsequent acidosis processes. Sodium bromide exhibits species-specific pharmacokinetic characteristics, competes with chloride ions for renal tubular reabsorption sites, and serves as a marker for extracellular fluid volume. Sodium bromide can be used in the research of epilepsy and related neurological diseases.

Palmitic acid
0 ImagesPalmitic acid is a long-chain saturated fatty acid commonly found in both animals and plants. PA can induce the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in in mouse granulosa cells. Palmitic acid is used to establish a cell steatosis model.

Lactic acid sodium (60% w/w in water)
0 ImagesLactic acid (DL-Lactic acid) sodium (60% w/w in water) is a hydroxycarboxylic acid receptor 1 (HCAR1) activator and an epigenetic modulator inducing lysine residues lactylation. Lactic acid sodium (60% w/w in water) is a glycolysis end-product, bridging the gap between glycolysis and oxidative phosphorylation. Lactic acid sodium (60% w/w in water) is an oncometabolite and has immune protective role of lactate in anti-tumor immunity. Lactic acid sodium (60% w/w in water) also has antimicrobial activity, which can be used as a food preservative.
This product has a content (w/w) of 60%, and 1 mL of the system contains 798 mg of Lactic acid sodium, i.e., a concentration of 798 mg/mL (i.e., 7.12 M).

Methyl-β-cyclodextrin
0 ImagesSynonyms: Methyl-beta-cyclodextrinMethyl-β-cyclodextrin (Methyl-beta-cyclodextrin) is a cyclic heptasaccharide used to deliver hydrophobic agents based on its property of solubilizing non-polar substances. Methyl-β-cyclodextrin is also extensively used as a cholesterol-depleting reagent. Methyl-β-cyclodextrin strongly reduces clathrin-dependent endocytosis. Methyl-β-cyclodextrin blocks cell migrasome formation.

Cholesterol (from animal)
0 ImagesCholesterol (from animal) is the major sterol in mammals. It is making up 20-25% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol (from animal) plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins. Cholesterol (from animal) is also an endogenous estrogen-related receptor α (ERRα) agonist.
