R-C-5736	MTX-PEI25k (Branched chain)	PEI-MTX,MTX-PEI,Polyethyleneimine(PEI)is a cationic polymer,it widely used as a gene delivery vector.PEI can complex with nucleic acids,protect them from degradation,and facilitate their intracellular delivery.Additionally,PEI possesses protonatable amino groups that enable endosomal escape, enhancing gene expression.MTX refers to methotrexate, a chemotherapy drug that inhibits the synthesis of nucleotides,leading to the suppression of DNA replication and cell proliferation.PEI-MTX conjugate combines the beneficial properties of both PEI and MTX for targeted drug delivery.The MTX moiety in the conjugate acts as a targeting ligand that can specifically bind to folate receptors,which are frequently overexpressed on the surface of cancer cells.	price>
R-C-5737	PEG2K-Se-Se-PEI20K	PEG-Se-Se-PEI,PEI-Se-Se-PEG,The disulfide bonds linking the PEI and Se atoms in the conjugate are sensitive to the intracellular environment,specifically the high levels of reductive agents such as glutathione.This sensitivity allows for the controlled release of the payload (e.g,genes or drugs) in the target cells.The reduction of the disulfide bonds leads to the detachment of the payload from the delivery system,facilitating its release and subsequent biological activity.	price>
R-C-5740	Perfluorononanoic acid-PAMAM-SS-PEG	PFNA-PAMAM-SS-PEG combines the hydrophobic properties of PFNA, the encapsulation capabilities of PAMAM, the controlled release mechanism of the disulfide bonds, and the advantages of PEGylation. This conjugate offers a platform for the development of targeted drug delivery systems, where the payload can be efficiently encapsulated within the dendrimer and released in a controlled manner in response to the reducing cellular environment.	price>
R-C-5748	PAMAM(Generation 0)-C14	The terminal groups of PAMAM are precisely controllable,and as drug and gene carriers,they have high stability,good biocompatibility,and no immunogenicity.Generation 0 PAMAM has the characteristics of dendritic compounds and is easy to synthesize non-toxic.	price>
R-C-5749	PNIPAAM2000-COOH	PNIPAAm is a substance with an extremely unique molecular structure, where the isopropyl group on its molecule is a strongly hydrophobic group, while the amide bond is a highly hydrophilic group with strong hydrogen bonding ability in the aqueous phase. Polymer materials prepared using NIPAAm as a framework generally exhibit good temperature sensitivity and exhibit a unique, reversible phase transition behavior.	price>
R-C-5775	PEG-P(DEA39-DPA61)	PEG-PDEA-PDPA,PDEA and PDPA are pH-responsive polymers that can undergo changes in their conformation and properties in response to changes in pH. These polymers are typically cationic at a low pH (such as in an acidic environment), making them suitable for drug delivery applications in acidic environments like tumors or intracellular compartments.	price>
R-C-5776	PS6500-b-PEG4000-COOH	PS-b-PEG-COOH,Polystyrene(PS)is a kind of polymer synthesized by free radical addition reaction of styrene monomer,and polyethylene glycol(PEG)is an oligomer or polymer of ethylene oxide.The product is non-toxic,non irritant,slightly bitter in taste,good in water solubility and good in compatibility with many organic components.This product is only used for scientific research experiments and is not intended for clinical human use.	price>
R-C-5783	PEI1.8K-Nonadecafluorodecanoic Acid	PEI-Nonadecafluorodecanoic Acid,Polyethyleneimine (PEI) is a cationic polymer with repeating ethyleneimine units.Nonadecafluorodecanoic acid (NFDA) is a perfluorinated carboxylic acid with nineteen fluorine atoms. It is a hydrophobic compound that can interact with hydrophobic surfaces or molecules.When PEI and NFDA are combined, they can form a complex through electrostatic interactions and hydrophobic interactions. The positive charges of PEI can interact with the carboxylate groups of NFDA, while the hydrophobic fluorocarbon chain of NFDA can interact with hydrophobic entities.	price>
R-C-5787	PAMAM Dendrimer G2.5 Caboxylate Sodium Salt	Polyamidoamine(PAMAM)dendrimers are hyperbranched polymers with unparalleled molecular uniformity, narrow molecular weight distribution, defined size and shape characteristics and a multifunctional terminal surface.These nanoscale polymers consist of an ethylenediamine core, a repetitive branching amidoamine internal structure and a primary amine terminal surface.	price>
R-C-5804	PAMAM 4.5-COOH	Poly(amidoamine) (PAMAM) dendrimers,known as artificial proteins, have unique and well-defined molecular size and structure. It has previously been used to mimic protein-crystal interaction during biomineralization.Generation 4.5(4.5G)PAMAM with carboxylic acid(PAMAM-COOH)was synthesized and utilized to remineralize the surface of etched enamel in vitro.	price>
