R-BI-0017	Methacrylate-PEG-biotin	Methacrylate-Polyethylene glycol--biotin,Methacrylate-PEG-biotin from ruixi.Methacrylate-PEG-biotin is a linear heterobifunctional PEG reagent with a Methacrylate a succinimidyl biotinl ester group. It is a useful crosslinking reagent with a PEG spacer.PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.	price>
R-BI-0018	IA-PEG-biotin	Iodoacetate---Polyethylene glycol--biotin ,IA-PEG-biotin from ruixi.Iodoacetyl (IA) functionalized polyethylene glycol (IA PEG) is a thiol (-SH) group reactive PEG derivative that can be used to modify biomolecules or other materials via their available thiol groups. Iodine group can be easily replaced by thiol group to form a stable carbon thiol bond.	price>
R-BI-0019	Chloride-PEG-biotin	Chloride---Polyethylene glycol--biotin ,Chloride-PEG-biotin from ruixi.Chloride-PEG-biotin is a linear heterobifunctional PEG reagent with a Chloride a succinimidyl biotinl ester group. It is a useful crosslinking reagent with a PEG spacer.PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.	price>
R-BI-0020	TCO-PEG-biotin	TCO-Polyethylene glycol--biotin,TCO-PEG-biotin from ruixi.TCO-PEG-biotin is a biotinylation reagent containing a TCO moiety for inverse electron demand Diels-Alder cycloaddition reactions. TCO will react with tetrazines via inverse electron demand Diels-Alder cycloaddition to form a stable dihydropyridazine linkage. The extremely fast kinetics and selectivity enables the conjugation of two low abundance biopolymers in an aqueous and otherwise complex chemical environment. This bioorthogonal reaction possesses excellent selectivity and biocompatibility such that the complimentary partners can react with each other within richly functionalized biological systems, in some cases, living organisms.	price>
R-BI-0021	Tetrazine-PEG-biotin	Tetrazine-Polyethylene glycol--biotin ,Tetrazine-PEG-biotin from ruixi.Tetrazine PEG derivatives are used to react with TCO (transcyclooctene) groups. The reaction of tetrazine and TCO is a bioorthogaonal reaction that enables the conjugation of two molecules in aqueous solution fast and efficiently. Tetrazine PEG derivatives have excellent water solubility, possess fast kinetics and stability in aqueous buffer. They are one of the best pegylation reagents to modify proteins, peptides, antibodies, biopolymers and particles via copper free Click Chemistry reaction.	price>
R-CN-009	endo-BCN-PEG2-Biotin	endo-BCN-PEG2-Biotin,endo-BCN-polyethylene glycol2-Biotin from ruixi.The BCN molecule can be chemically linked to the copper azide molecule via a click free reaction.Biotin derivatives can efficiently label biotin in antibodies, proteins and other macromolecules containing major amines. Hydrophilic polyethylene glycol (PEG) can greatly improve the water solubility of the reagent.	price>
R-CT-052	Biotin-PEG4-methyltetrazine	Ruixi bio can provide such products as biotin-peg4-methyltetrazine,a biotinylated reagent activated by methyltetrazine,which can react with compounds containing TCO through anti electron demand Diels alder reaction to form stable covalent bonds without the need for copper catalyst or increasing the catalyst temperature.The Diels alder cycloaddition reaction of temperature tc0 with reverse electron demand of tetrazine compounds is a biorthogonal reaction with special kinetic characteristics (L>800-1s-1)and selectivity.	price>
R-CO-021	(4E)-TCO-PEG4-biotin	Trans cyclooctene (TCO),as a amphiphilic monomer, has been widely used in biological and material science research due to its advantages of no catalyst and fast reaction rate under physiological conditions.We can provide such products(4E)-TCO-PEG4-biotin.	price>
R-CL-018	Biotin-PEG3-SS-DBCO	Dbco(dibenzocyclooctyne) is a kind of cycloalkyne.It can react with azide through strain promoted 1,3-dipolar cycloaddition in aqueous solution.This biorthogonal reaction is also called copper free click reaction.This reaction has excellent selectivity and biocompatibility,so complementary reagents can form covalent bonds with functional biological systems.Copper free click reaction has always been a powerful tool for catalyst free bioconjugation.Dbco reagent has fast affinity and stability in aqueous buffer,which can be used to label azide modified biomolecules with high specificity and reactivity.Ruixi can provide such products Biotin-PEG3-SS-DBCO.	price>
R-CL-019	Dde Biotin-PEG4-alkyne	Dde Biotin-PEG4-alkyne is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.PROTACs contain two different ligands connected by a linker;one is a ligand for an E3 ubiquitin ligase and the other is for the target protein.PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.Ruixi can provide Dde Biotin-PEG4-alkyne.	price>
