Medchemexpress LLC Galactose oxidase, Dactylium dendroides (GOase) | 9028-79-9 | ≥100 U/mg protein | ~68.5 kDa | 150 U
Galactose Oxidase, Dactylium dendroides (GOase) is a type II copper metalloenzyme derived from fungus, containing a single polypeptide. It is widely utilized in biochemical research due to its catalytic activity. This enzyme facilitates the two-electron oxidation of primary alcohols, converting them into their corresponding aldehydes, and concurrently reduces dioxygen to hydrogen peroxide.
- Catalyzes two-electron oxidation of primary alcohols.
- Reduces dioxygen to hydrogen peroxide.
- Soluble in pure water (1 mg/mL).
- Recommended buffer for catalytic reaction is 0.1 M Potassium phosphate buffer, pH 6.0.

Echelon Biosciences Research Labs 3,3 -BISOLEOYL-LBPA 500 ug
3,3-Bisoleoyl-LBPA ((R,R)-3,3-Bisoleoyl-lysobisphosphatidic acid) is the biologically inactive isomer of LBPA.Lysobisphosphatidic acids (LBPAs), known also as bis-(monoacylglycerol)phosphates (BMPs) are specialized lipids reported to play a role in intracellular protein and lipid transport in healthy cells. Their accumulation was observed in pathologic liver tissue, and they also serve as antigens for auto-antibody generation in a human autoimmune condition termed antiphospholipid syndrome. Accumulation of LBPAs in intracellular, often multilamellar membranes is related to biomembrane polymorphism which may impact intracellular cholesterol transport. This item is non returnable

Medchemexpress LLC Pelargonidin (chloride) | 134-04-3 | 99.1% | 306.70 | 5 MG
Pelargonidin chloride is an anthocyanidin that functions as a scavenger of nitric oxide radicals and possesses antioxidant activities. It has been shown to inhibit cell viability and induce cell cycle arrest at the sub-G1 phase. Additionally, it enhances the mRNA and protein expression of HO-1, NQO1, and Nrf2, and improves Aβ-induced memory and learning impairment. It is for research use only.
- Scavenges nitric oxide radicals
- Possesses antioxidant activities
- Inhibits cell viability
- Induces cell cycle arrest at sub-G1 phase
- Increases mRNA and protein expression of HO-1, NQO1, and Nrf2
- Improves Aβ-induced memory and learning impairment
