Catalog	name	Description	price
R-C-867	4arm-PEG5K-TK-COOH	Keto mercaptan is a reactive group of ROS.Keto mercaptan polymers are widely used in inflammation and tumor.Inflammation and tumor have high levels of ROS, which can break keto mercaptan chemical bond and realize drug release. Polyethylene glycol(PEG)is a kind of high molecular polymer,which has no irritation,slightly bitter taste,good water solubility and good compatibility with many organic components.	price>
R-C-870	Oil soluble manganese dioxide nanoparticles（25nm）	The oil soluble manganese dioxide nanoparticles,with a diameter of about 25 nm, were dispersed in organic solvent(chloroform).	price>
R-C-874	Silybin biotin	Silymarin is an antioxidant derived from a plant called milk thistle.Silymarin can stabilize the membrane of liver cells,maintain the integrity of liver cells, prevent the toxin from penetrating and damaging the liver,accelerate the synthesis of DNA (deoxyribonucleic acid)of liver cells,prevent liver cirrhosis, fatty liver,cholangitis,psoriasis and other diseases,and inhibit the growth and differentiation of liver cancer,prostate cancer,breast cancer and cervical cancer cells.	price>
R-C-875	Custom adriamycin materials	Doxorubicin is also known as 14 hydroxy positive dingmycin 14 hydroxydaunorubicin,doxorubicin,adriamycin,adriamycin and hydroxyerythromycin are anthracycline antitumor antibiotics produced by Streptomyces peucetius subsp Caesius.They are cell cycle nonspecific drugs(CCNSA)and are sensitive to s and M phases.The hydrochloride is orange needle crystal.	price>
R-C-883	Peptide (YGRKKRRQRRR) modified carbon quantum dots	Polypeptides are the active substances to achieve various functions in organisms.The modification of polypeptides is mainly the modification of the main chain structure and side chain groups of peptide chain.The modified peptide drugs can significantly reduce immunogenicity,reduce toxicity, increase water solubility,prolong the action time in vivo,change the distribution in vivo and so on.The main modifiers are dextran,polyethylene glycol and tetranitroethane. Peptides can modify quantum dots,other groups,etc.,and can also customize special peptide modified products.	price>
R-C-887	Disulfide modified paclitaxel	Disulfide bond is a chemical bond that connects the sulfhydryl groups of two different cysteine residues in different peptide chains or the same peptide chain.Disulfide bond is a relatively stable covalent bond,which plays a role in stabilizing the spatial structure of peptide chain in protein molecules. Paclitaxel can make tubulin and tubulin dimer of microtubule lose dynamic balance,induce and promote tubulin polymerization,microtubule assembly,prevent depolymerization,so as to stabilize microtubule,inhibit the mitosis of cancer cells and trigger apoptosis,and then effectively prevent the proliferation of cancer cells and play an anti-cancer role.	price>
R-C-889	Glycyrrhizic acid nanoparticles（100nm）	Glycyrrhizic acid is an organic compound with the molecular formula of c42h62o16. As a drug,it has anti-inflammatory and anti allergic effects. Glycyrrhizic acid is the main active ingredient in Glycyrrhiza uralensis. Glycyrrhizic acid and its series of products can inhibit the growth of sarcoma and cancer cells,and the inhibition rate of AIDS is as high as 90%.It has a strong effect on increasing human immune function,and is also a good food additive and spice base material.	price>
R-C-890	HSA-CY5	Human serum albumin (HSA)is the main plasma protein.It can bind with water,Ca (2 +),Na(+),K(+),fatty acids,hormones and drugs,and maintain the colloidal osmotic pressure of blood.Cy5 fluorescent dyes:dyes that emit fluorescence.Cy5 is very sensitive to its surrounding electronic environment,which can be used for enzyme detection.The conformational changes of attachment proteins can lead to positive or negative changes of fluorescence emission.Cyanine dye is a relatively old fluorescent dye,but it is the basis for other fluorescent dyes to improve their brightness,light resistance and quantum yield.	price>
R-C-892	Aminated mesoporous silica coated silver nanoparticles（100NM ）	Porous silica has the characteristics of large specific surface area,good chemical stability,good biocompatibility and controllable pore size.Currently, the main synthetic methods of mesoporous silica include sol gel method, hydrothermal method and so on.Silver nanoparticles have been widely used as catalyst materials,antistatic materials,low-temperature superconducting materials and medical antibacterial materials because of their ultra-high specific surface area,surface activity,conductivity and antibacterial properties.	price>
R-C-894	Triptolide-Biotin	Tripterygium wilfordii is an effective proteasome inhibitor,which can induce cancer cell apoptosis by inhibiting proteasome activity.Biotin was well tolerated.	price>
