QY-C-0431	Ramucirumab	Ramucirumab a monoclonal antibody product is provided by Ruixi. Ramucirumab is an antagonist of vascular endothelial growth factor receptor. It can specifically bind to VEGF receptor and block the coordination of VEGF ligand, VEGF-A, VEGF-C and vegf-d. Therefore, ramorumab can inhibit the activation of VEGF receptor stimulated by ligand, thus inhibiting ligand induced proliferation and human endothelial cell migration. In animal experiments, ramorumab inhibited angiogenesis.	price>
R-Z-0194	Fe3O4-T2 imaging liposomes	Fe3O4-T2 imaging liposomes,coated with Fe3O4-T2 imaging liposomes from ruixi.Superparamagnetic iron oxide particles(USPIO/SPIO)contrast agent, its mechanism is to reduce T1,T2 relaxation time,mainly used in various medical applications of magnetic resonance imaging, especially for the reticuloendothelial system in vivo,can be used for liver,lymph,bone marrow and other organs enhancement.Fe3O4 also has the following uses:bifunctional imaging, T1 and T2 weighted imaging;long half-life of blood, up to 30 minutes; specificity of reticuloendothelial system;good venography effect;it can be used for cell labeling in vivo tracing experiment.	price>
R-Z-0195	Doxorubicin&siRNA co-loaded Liposomes	Doxorubicin&siRNA co-loaded Liposomes ,Doxorubicin-siRNA co-loaded Liposomes from ruixi.Doxorubicin siRNA co loaded liposomes are liposomes co loaded with doxorubicin and nucleic acid.Liposome is a common drug carrier, which can slow-release drugs, change the mode of drug uptake by cells, greatly reduce the side effects of chemotherapy drugs and increase the safety. Adriamycin is an antineoplastic antibiotic, which can inhibit the synthesis of RNA and DNA. It has the strongest inhibitory effect on RNA. It has a wide anti-tumor spectrum. It has effects on many kinds of tumors. It belongs to cycle nonspecific drug and has killing effect on tumor cells of various growth cycles.	price>
R-Z-004	Prussian Blue liposomes	Prussian Blue liposomes from ruixi.Prussian blue liposomes is a kind of blue dye. Its structure is formed by the coordination of Fe (Ⅱ) and Fe (Ⅲ) with cyano (- CN -). As a coordination polymer, Prussian blue has excellent magnetic, electrical and optical properties. In biomedical imaging, Prussian blue nanoparticles have both photoacoustic imaging and magnetic resonance imaging, and have great application advantages in stem cell tracking and multimodal disease diagnosis.	price>
R-Z-0665	Liver targeting liposomes surface modified with (GA) glycyrrhetinic acid	Liver targeting liposomes surface modified with (GA) glycyrrhetinic acid,Liver targeting liposomes surface modified with glycyrrhetinic acid from ruixi.Liver targeting liposomes surface modified with glycyrrhetinic acid is an active targeting GA liposome.As a passive drug targeting carrier, liposomes are easily absorbed by reticuloendothelial system in vivo. The specific surface modification of liposomes, targeted ligand modified liposomes can effectively improve the delivery of GA to liver lesion cells and achieve active targeting effect.	price>

R-R-0920	N-Oleoyl leucine	N-Oleoyl-L-leucine/CAS.136560-76-4, also known as OLL, is an endocannabinoid-like compound that has been studied for its potential role in regulating lipid metabolism and energy balance. It is a derivative of oleic acid and L-leucine and is thought to have effects on satiety, food intake, and energy expenditure. OLL has been researched for its potential as a target for obesity and related metabolic disorders.	price>
R-CL-009	N-Boc-Pyridine dithioethylamine	Upper protective group:amine interacts with di tert butyl dicarbonate and weak bases (such as potassium carbonate,triethylamine,etc.)Two phase reactions,such as DCM and H2O,can be used.Deprotection:treated with hydrochloric acid.The products are isobutene and carbon dioxide.BOC protecting groups are mainly used to protect amino groups in liquid-phase peptide synthesis chemistry.Rui can provide N-Boc-Pyridine dithioethylamine.	price>
R-CL-031	3-(2-Pyridyldithio)propanoic acid	Ruixi Biotechnology Co.,Ltd.is a well-known biotechnology company in China.At present,the company products mainly include synthetic phospholipids,PEG derivatives,block copolymers,gold nanoparticles,magnetic nanoparticles,mesoporous silica,reactive fluorescent dyes,fluorescent quantum dots,click chemistry and macrocyclic ligands and so on.We can provide special customized products.	price>
R-Z-0193	Gadolinium(GD)-T1 imaging liposomes	Gadolinium(GD)-T1 imaging liposomes,Gadolinium-T1 imaging liposomes from ruixi. Gadolinium-t1 imaging liposomes can be used for nuclear magnetic resonance (NMR) imaging of human body, inhibitors for controlling the chain reaction level of nuclear power plants, and additives for samarium cobalt magnets. MRI contrast agent can be divided into longitudinal relaxation contrast agent (T1 preparation) and transverse relaxation contrast agent (T2 preparation). T1 preparation shortens T1 through the direct action of hydrogen nucleus and paramagnetic metal ions in water molecules, so as to enhance the signal and make the image brighter; T2 preparation shortens T2 by interfering with the inhomogeneity of external local magnetic environment, which makes the neighboring hydrogen protons quickly produce phase (diphase) in relaxation, so as to weaken the signal and make the image dark. At present, the T1 contrast agent products on the market are GD gadolinium and Gd derivative products, and Gd DTPA gadopentetate meglumine is the most commonly used.	price>
