PEG

Biotin-PEG7-amine is a biotin PEG reagent that is reactive with NHS ester or with carboxutlic acid in the presence of EDC or HATU activator. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG11-amine is monodisperse PEGylated biotinylation reagent.The amine group can be coupled to carboxyl groups or 5'phosphate groups to form stable amide bonds. The hydrophilic PEG spacer increases aqueous solubility of the molecules conjugated to the biotin compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG11-Mal is a PEGylated biotin reagent PEG linker containing a maleimide (Mal) group.The maleimide gmoiety reacts specifically with sulfhydryl groups (at pH 6.5-7.5) to form a thioether linkage. The hydrophilic PEG spacer increases solubility in aqueous media of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG7-azide is PEG-containing click chemistry tool for biotinylation Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG11-azide is monodisperse PEG biotinylation reagent that can undergo click chemistry with alkyne containing molecule. The hydrophilic PEG spacer increases aqueous solubility of the molecules conjugated with biotin. It also minimize steric hindrance involved with the binding to avidin molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-N-amido-PEG2-acid is a PEG linker containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-N-amido-PEG3-acid is a PEG linker containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-N-amido-PEG5-acid is a PEG linker containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.
