R-Z-131	Tocopherol-PEG-BIOTIN	Tocopherol-polyethylene glycol-Biotin,Tocopherol-PEG-BIOTIN from ruixi.Biotin, also known as vitamin H and coenzyme R,is the coenzyme of various carboxylase, which plays the role of CO2 carrier in the carboxylase reaction.	price>
R-R-0430	PC Biotin-PEG3-NHS ester	PC Biotin-PEG3-NHS ester/PC Biotin-PEG3-NHS carbonate ester/CAS 2353409-93-3 is a targeted nanoparticle that is being developed to treat hepatitis C. It consists of biotin conjugated to PEG3-NHS ester and has been shown to have minimal human genome interference. The efficiency of Pc biotin-PEG3-NHS ester was shown by the release of HCV from infected cells at a rate of 16% in vitro, while cell viability remained at 100%. This agent can be used as a vaccine against hepatitis B virus (HBV) and has been demonstrated to have significant cytotoxicity against HBV. In addition, Pc biotin-PEG3-NHS ester has been shown to be a potent immunogen with an elimination half life of less than 1 hour in mice.	price>
R-R-0431	PC-Biotin-PEG4-PEG3-azide	PC-Biotin-PEG4-PEG3-azide/CAS: 2055198-04-2 is useful for introducing a biotin moiety to alkyne-containing biomolecules using Click Chemistry. The extended hydrophilic spacer arm provides high solubility to the labeled molecules in aqueous media. Captured biomolecules can be efficiently photoreleased using near-UV, low intensity lamp (e.g. 365 nm lamp at 1-5 mW/cm2).	price>
R-R-0432	Tetrazine-PEG4-biotin	Tetrazine-PEG4-biotin is a cleavable 4 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Tetrazine-PEG4-biotin is a click chemistry reagent, itcontains a Tetrazine group that can undergo an inverse electron demand Diels-Alder reaction (iEDDA) with molecules containing TCO groups.	price>
R-BI-0002	Hydrazide-PEG-biotin	Hydrazide---Polyethylene glycol--biotin,Hydrazide-PEG-biotin from ruixi.Biotin-PEG4-Hydrazide) is an aldehyde-reactive biotinylation reagent that contains a 4-unit polyethylene glycol (PEG) spacer arm for increased hydrophilicity.Biotin-PEG-Hydrazide enables biotinylation of glycoproteins and other molecules containing aldehydes or oxidizable sugar groups.	price>
R-BI-0003	Acrylates-peg-biotin	Acrylates---Polyethylene glycol--biotin,Acrylates-peg-biotin from ruixi.Acrylates PEG Biotin is one of acrylic acid functionalized Biotin PEG derivatives can be used to make hydrogel via radical polymerization process. It can also be used to modify polymer or nanoparticles. Resulted biotin can bind to avidin or streptavidin with high affinity. 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>
