95 Results for "contrast agent" in MCE Product Catalog:
Cat. No.: HY-115853
CAS No.: 78668-34-5
Target:
Research Areas:
Pyclen forms kinetically and thermodynamically stable nine-coordinate Ln (III) complexes, as well as Mn (II)-based MRI contrast agents. Pyclen-Based Mn(II) Complexes can be used for liver-specific MRI .
Synonyms: mPEG10000-SC; mPEG10000-Succinimidyl ester
Target:
Research Areas:
Tempone (4-Oxo-Tempo) is a nitroxide radical spin label and ROS scavenger. Tempone induces cytotoxicity in lymphoma cells. Tempone serves as a substrate for intracellular reduction to hydroxylamine, rapidly equilibrates between intracellular and extracellular compartments, reduces nitroxide radical spin labels at the ubiquinol site of the respiratory chain, and acts as an alternative terminal electron acceptor when electron flow to oxygen is blocked. Tempone serves as a superoxide sensor, a T2-weighted MRI contrast agent, and a dynamic nuclear polarization polarizing agent for 13C. Tempone inhibits superoxide and peroxynitrite, hydroxyl radical generation, nitrotyrosine formation, and poly (ADP-ribose) formation, and alleviates renal dysfunction and injury in ischemia/reperfusion and hydrogen peroxide-induced injury. Tempone can be used for research on ischemia-reperfusion injury, acute renal failure, and lymphoma .
Cat. No.: HY-106594B
CAS No.: 12240-15-2
Synonyms: Pigment blue 27
Cat. No.: HY-D2062
CAS No.: 1448146-89-1
Synonyms: mPEG20000-SC; mPEG20000-Succinimidyl ester
Cat. No.: HY-B2119
CAS No.: 41945-48-6
Synonyms: Tauroglycocholic acid sodium salt
Target:
Research Areas:
Sodium tauroglycocholate (Tauroglycocholic acid sodium salt) is a multifunctional surfactant and penetration enhancer that can serve as a cholegraphic contrast agent. In organic solvents, Sodium tauroglycocholate embeds and stabilizes invertase by forming reverse micelles, and prolongs its active lifespan. In terms of transdermal absorption, Sodium tauroglycocholate effectively regulates the flux of aminophylline through snake slough by binding to keratin filaments, disrupting keratinocytes and altering lipid components of the stratum corneum. It exhibits rapid penetration characteristics without lag time at a concentration of 100 μg/mL. Sodium tauroglycocholate does not interfere with the hepatic uptake of Gd-EOB-DTPA by the bile acid transport system in rat hepatocytes .
Cat. No.: HY-B0594R
CAS No.: 66108-95-0
Target:
Research Areas:
Iohexol (Standard) is the analytical standard of Iohexol. This product is intended for research and analytical applications. Iohexol is a non-ionic, water-soluble contrast agent used as a reference marker for the determination of glomerular filtration rate (GFR) at the level of renal function. Iohexol can be used for contrast in myelography, computerized tomography (cisternography, ventriculography) and MicroCT imaging .
Target:
Research Areas:
Iomeprol is a nonionic X-ray contrast agent with low osmotic pressure, stable chemical properties, and can withstand high temperature sterilization. Iomeprol can be widely used in vascular, body cavity, and gastrointestinal angiography examinations .
Cat. No.: HY-164725
CAS No.: 3023869-94-2
Research Areas:
Cat. No.: HY-D1450
CAS No.: 155613-98-2
Synonyms: S01448
Target:
Research Areas:
IR-1048 is a nitroreductase (NTR)-responsive near-infrared fluorescence (NIR)/photoacoustic (PA) imaging probe and photothermal agent. IR-1048 is coupled with a nitroimidazole group to form IR-1048-MZ. IR-1048-MZ is catalytically reduced by NTR in a hypoxic environment, restoring strong near-infrared absorption and fluorescence emission (NIR II window), while activating the photothermal effect. IR-1048 relies on NTR-mediated electron transfer to relieve intramolecular fluorescence quenching, achieving specific imaging and photothermal ablation of tumor hypoxic areas. IR-1048 is mainly used for high-contrast NIR II/photoacoustic imaging and photothermal therapy research and tumor diagnosis of the tumor hypoxic microenvironment .
Cat. No.: HY-129242S
CAS No.: 80404-14-4
Synonyms: 4-Oxo-Tempo-15N,d16
Tempone- 15N,d16 (4-Oxo-Tempo 15N,D16) is the deuterated, 15N-labeled Tempone (HY-129242). Tempone (4-Oxo-Tempo) is a nitroxide radical spin label and ROS scavenger. Tempone induces cytotoxicity in lymphoma cells. Tempone serves as a substrate for intracellular reduction to hydroxylamine, rapidly equilibrates between intracellular and extracellular compartments, reduces nitroxide radical spin labels at the ubiquinol site of the respiratory chain, and acts as an alternative terminal electron acceptor when electron flow to oxygen is blocked. Tempone serves as a superoxide sensor, a T2-weighted MRI contrast agent, and a dynamic nuclear polarization polarizing agent for 13C. Tempone inhibits superoxide and peroxynitrite, hydroxyl radical generation, nitrotyrosine formation, and poly (ADP-ribose) formation, and alleviates renal dysfunction and injury in ischemia/reperfusion and hydrogen peroxide-induced injury. Tempone can be used for research on ischemia-reperfusion injury, acute renal failure, and lymphoma .
