    Dimethyl sulfoxide, meets analytical specification of Ch.P. 67-68-5 ≥99.0%
    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.

    Lipopolysaccharides, from E. coli O55:B5
    Lipopolysaccharides, from E. coli O55:B5 (LPS, from Escherichia coli (O55:B5)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O55:B5) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O55:B5 possess the typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O55:B5 activate TLR-4 in immune cells, exhibit high pyrogenicity, and demonstrate dose and serotype specificity. Lipopolysaccharides, from E. coli O55:B5 can be widely used to induce cellular inflammation and establish animal models related to inflammation.
    It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.
