R-C-4809	PDLA9.5K-PNIPAAm30K	PNIPAAm poly (N-isopropylacrylamide) is a material with extremely molecular structure. The isopropyl group on its molecule is a strong hydrophobic group, and the amide bond is a strong hydrophilic group, which has a strong ability to form hydrogen bonds in the aqueous phase. Poly (n-acrylamide) (PNIPAAm) is one of the widely studied temperature sensitive polymers.	price>
R-C-4959	Polyethylenimine-RT3	Polyethylenimine (PEI) is a hydrophilic cationic polymer widely used as a nonviral nucleotide delivery reagent. Branched PEI can be synthesized by cationic ring-opening polymerization of aziridine. PEI-based particles can also be used as adjuvants for vaccines.	price>
R-C-4961	PBAE polymer 447	Poly(β-amino ester)s(PBAEs)are pH-sensitive,biodegradable polymers that have been widely investigated as both gene and drug delivery vectors.	price>
R-C-4989	PEO136-PAA72 Na	Whether in acidic or alkaline conditions, PAA-PEO can maintain its comb like structure. Due to the frequent grafting of comb like PEO branches onto the comb back PAA main chain, these comb like branches control the configuration changes of the dispersant in aqueous solution, resulting in a strong steric hindrance effect.	price>
R-C-5012	PEI25K-ce6	Polyethyleneimine(PEI) is a water-soluble polymer.Colorless or light yellow viscous liquid,with hygroscopicity, soluble in water and ethanol, insoluble in benzene,and can also provide PEG grafting modification of dihydroporphyrin,dihydroporphyrin polyethylene glycol polyethylene imine.	price>
R-C-5070	PPS-PEG350-MAL	Amphiphilic block copolymers based on hydrophobic polysulfide(PPS)and hydrophilic polyether(PEG)have been used for solubilization and dispersion of single-walled carbon nanotubes(SWNTs).The high concentration aqueous dispersion was stable for several months.	price>
R-C-5071	PPS-polyethylene glycol550-MAL	Amphiphilic block copolymers based on hydrophobic polysulfide(PPS)and hydrophilic polyether(PEG)have been used for solubilization and dispersion of single-walled carbon nanotubes(SWNTs).The high concentration aqueous dispersion was stable for several months.	price>
R-C-5072	Maleimide-PEG750-Polyphenylene Sulfide	Amphiphilic block copolymers based on hydrophobic polysulfide(PPS)and hydrophilic polyether(PEG)have been used for solubilization and dispersion of single-walled carbon nanotubes(SWNTs).The high concentration aqueous dispersion was stable for several months.	price>
R-C-5105	PEI25KD-PEG2000-FA	Polyethylenimine-Polyethylene glycol-Folate polyethylene imine polyethylene glycol folate,is an AB block copolymer with folate groups at the end of PEG.PEI-PEG-Folate is a cationic polymer that can be used in drug delivery systems.	price>
R-C-5106	PEI-PEG350-PEI	Copolymers of cationic poly(ethylene imine) (PEI) and polyethylene glycol (PEG) markedly improve in vitro and in vivo delivery of oligonucleotides and nucleic acids (DNA, siRNA).PEI-PEG-PEI can have varying MW of PEI and MW of PEG.PEG-PEI drug conjugates,polyplexes or nanoparticles can be prepared with a dynamic range of size,surface charge,and stability.Properties important to transfection efficiency.	price>
