Pengsheng biology promotes the development of polyethylene glycol modifier in China

[member report of China Pharmaceutical network] Shanghai Pengsheng Biotechnology Co., Ltd is a high-tech enterprise dedicated to the production and development of polyethylene glycol and its derivatives Pengsheng biotechnology has a mature industrial structure from various raw materials polyethylene glycol to various polyethylene glycol activators, with the concept of promoting the development and popularization of domestic polyethylene glycol modifiers and new polyethylene glycol On December 26, 2017, Shanghai Pengsheng Biotechnology Co., Ltd became a member of China Pharmaceutical network junior list Main products: modified PEG, amino peg, sulfhydryl peg, hydroxypeg, carboxyl peg, acrylic acid peg, maleimide peg, phospholipid peg, active ester peg, azide peg, biotin peg, folic acid peg, fluorescein, rhodamine peg, single functional group peg, the same as double functional group peg, multi arm peg It is recommended that [ps2-defa phospholipid peg folate dspe-peg-fa ps2-defa] 1,2-distearoyl-sn-glycoro-3-phosphoethanolamine (DSPE) conjugated polyethylene glycol PEG is a phospholipid, and the combination of DSPE and peg is hydrophilic and hydrophobic It can be used in drug delivery, gene transfection and vaccine Peg phospholipid significantly improved the blood circulation time and stability of the capsule These materials can also be used for targeted drug delivery by modifying their surfaces with targeted ligands, such as antibodies, peptides Ps2-defa phospholipid peg folate dspe-peg-fa ps2-defa [ps2-mazazide peg maleimide n3-peg-mal] maleimide group reacts with sulfhydryl group at pH 6.5-7.5 room temperature to form stable thioether bond, while carboxylic acid group reacts with amine and acid amine active molecules at the other end Azido / azido functionalized polyethylene glycol (n3-peg-x) is a bifunctional peg derivative that can be used to modify proteins, peptides and other materials Azides can react with copper catalyzed alkynes in aqueous solution It can also be reduced to amines, while another functional group can react with other molecules or functional groups Ps2-maz azide peg maleimide n3-peg-mal Pengsheng biology provides cost-effective products to customers with the support of scientific research in Colleges and universities GPC, NMR and other instruments are used to ensure product quality We sincerely welcome customers from home and abroad to come to discuss cooperation and create a more brilliant tomorrow together Welcome to the booth of Shanghai Pengsheng Biotechnology Co., Ltd!
