Glyoxal (40% w/w in water)
Based on 1 Customer Validation
Glyoxal (40% w/w in water) is an α-oxoaldehyde that inhibits Aldose Reductase, Glutathione Reductase, and NADPH synthase. Glyoxal (40% w/w in water) exhibits cytotoxicity, triggers oxidative stress, induces ROS accumulation, lipid peroxidation, mitochondrial membrane potential collapse, DNA damage, apoptosis, and massive production of advanced glycation end products (AGEs). Glyoxal (40% w/w in water) depletes glutathione and activates MAPK phosphorylation. It has lower toxicity as a fixative than paraformaldehyde (PFA) and serves as a precursor for the synthesis of oxalates and dietary carcinogens. Glyoxal (40% w/w in water) is suitable for research related to calcium oxalate kidney stones, diabetes, atherosclerosis, cardiovascular diseases, retinopathy, and cataracts.

Glyoxal (40% w/w in water)-induced cellular injury, inflammation and oxidative stress can be alleviated by Resveratrol (HY-16561), Luteolin (HY-N0162), morin and Mangiferin (HY-N0290) as well as Clostridium butyricum through regulating immune signaling pathways or cellular detoxification systems, respectively[4].\n

Glyoxal (40% w/w in water) exhibits faster penetration efficiency through the cell membrane of COS-7 cells compared with PFA (HY-DY3003). It can rapidly terminate cellular endocytosis, and shows superior performance in terms of cell morphology, cytoplasmic protein cross-linking and nucleic acid fixation. It reduces the half amount of unfixed proteins and maintains the detection signal of RNA fluorescence in situ hybridization[3].
Glyoxal (40% w/w in water) enhances the fluorescence intensity of STED staining and multiple synaptic/skeletal proteins in rat hippocampal neurons compared with PFA; only the staining signals of LC3B and vimentin are weaker than those with PFA. It is suitable for a variety of cell and tissue samples including cardiac, neural and olfactory epithelial samples. When used for fixation of mouse olfactory epithelium and olfactory bulb, it also yields a higher signal-to-noise ratio for immunostaining[3].
Glyoxal (40% w/w in water) can be sequestered and bound by aspartame to reduce its free content and block in vitro glycation reactions. Additionally, the glyoxal-induced glycation of human serum albumin can be inhibited by Naringin (HY-N0153), Naringenin (HY-N0100), and Quercetin (HY-18085) via competitive occupation of the binding sites on lysine and arginine residues of the protein[4].
Glyoxal (40% w/w in water) can be captured and bound by Gallic acid (HY-N0523), Quercetin, glycine, serine, κ-carrageenan, alginic acid and pectin, thereby reducing the content of free Glyoxal in pH 7.0 phosphate buffer, pH 7.4 phosphate buffer, and lysine-glucose model system, respectively[4].
Glyoxal (GX) (50-200 μM; 8 days) (40% w/w in water) reduces the viability of wild-type and FANC pathway-deficient human aortic endothelial cells, with LD90 values of 0.12 mM and 0.125 mM, respectively[5].
