R-PL1245	mPEG-b-PASP	mPEG-b-PASP,Methoxy-poly(ethylene glycol)-block-poly(L-Aspartic acid) is a linear AB amphiphilic block copolymer	price>
R-PL1246	PASP-b-PEG-b-PASP	PASP-b-PEG-b-PASP,poly(L-Aspartic acid)-poly(ethylene glycol)-poly(L-Aspartic acid) is a linear ABA amphiphilic block copolymer	price>
R-BC-0006	PNIPAAm-b-PASP	POLY(N-ISOPROPYL ACRYLAMIDE)-b-polyaspartic acid,PNIPAAm-b-PASP,PASP-b-PNIPAAm from ruixi polyacrylic acid1200-thiol is an amphiphilic copolymer. Polyaspartic acid (PASP) belongs to a class of polyamino acids. Polyaspartic acid is easily broken by microorganisms and fungi because of its peptide bonds in the main chain. The final degradation products are ammonia, carbon dioxide and water, which are harmless to the environment. Therefore, polyaspartic acid is widely used. It can be used in water treatment, medicine, agriculture, daily chemical and other fields.	price>
R-OR-375	MPEG-Poly-L-aspartic acid	MPEG-Poly-L-aspartic acid from ruixi Polyaspartic acid (PASP) is a kind of poly amino acids. Polyaspartic acid is easily broken by microorganisms and fungi because of the peptide bond on its main chain. The final degradation products are harmless ammonia, carbon dioxide and water.	price>
R-C-407	PASP-PEG-NH2	Poly(L-Aspartic acid)-poly (ethylene glycol)-amine can be used to prepare drug loaded microspheres, microcapsules,vesicles and micelles,which can achieve sustained and controlled drug release.Amino group can react with molecules with carboxyl group, active ester,aldehyde group,etc.Polyethylene glycol can increase the solubility and stability of drugs,reduce the non-specific binding of charged molecules on the modified surface,and reduce the immunogenicity of peptides.	price>
R-C-408	PASP-PEG-COOH	Poly(L-Aspartic acid)-poly (ethylene glycol)-carboxylic acid is used in the research of drug delivery,tissue repair,biological modification and other biomedical fields.Carboxyl group,which can react with amino groups in lysine and other molecules in pH=7-8,is more stable than active ester group.Poly(L-Aspartic acid)-peg carboxyl(PASP-PEG-COOH) is a linear amphiphilic block copolymer (ABC), which has poly(L-Aspartic acid) as hydrophobic part and carboxyl functionalized peg as hydrophilic part.	price>
R-C-409	PASP-PEG-MAL	Poly(L-Aspartic acid)-poly (ethylene glycol)-maleimide is a linear amphiphilic block copolymer(ABC),with poly (L-Aspartic acid) as hydrophobic part and maleimide functionalized peg as hydrophilic part.P(L-Asp)-peg-mal has reactive groups on both parts,i.e.the side free COOH on P(L-Asp) can be used to modify the micelle core,while the mal group on PEG reacts with the sulfhydryl group of pH 6.5~7.5 at room temperature to form stable thioether bond.	price>
R-C-410	PASP-PEG-NHS	Poly(L-Aspartic acid)-poly (ethylene glycol)-N-hydroxysuccinimide is a water-soluble polymer,which is a new green water treatment agent.It has the characteristics of phosphorus free,non-toxic,pollution-free and completely biodegradable.At the same time,it has dispersing effect and can effectively prevent the corrosion of metal equipment.	price>
R-C-411	PASP-PEG-N3	Poly(L-Aspartic acid)-peg azide(pasp-peg-n3) is a linear amphiphilic block copolymer(ABC),which has poly(L-Aspartic acid)as hydrophobic part and azide functionalized peg as hydrophilic part.P(L-Asp)-peg-n3 has reactive groups on both parts,i.e.the side group free COOH on P(L-Asp)can be used to modify the micelle core,while N3 on PEG can be used to modify proteins,peptides and other materials.Azide groups can react with alkynes in copper catalyzed aqueous solution.It can also be easily reduced to amines.	price>
R-C-412	PASP-PEG-SH	Amino polyethylene glycol polyaspartic acid(nh2-peg-pasp)is one of the heterobifunctional PEG derivatives.The heterobifunctional amino peg polyaspartic acid has an amino group and a peg coupled polyaspartic acid.Pasp-peg-sh is one of the most commonly used biodegradable functional polymers and polypeptide amino acid copolymers.It can be used for passive targeting,active targeting and drug delivery of micelles and vesicles.	price>
