PEG

t-Boc-N-amido-PEG15-amine is a aqueous soluble PEG linker with an amino group and Boc-protected amino group. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-amido-PEG23-amine is a monodisperse PEG linker. The hydrophilic PEG spacer increases solubility in aqueous media. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Hydroxy-PEG10-t-butyl ester is a PEG linker containing a hydroxyl group with a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG2-NHS ester is an amine reactive biotinylation compound that can couple with primary amino groups (-NH2). The NHS group reacts specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG6-alcohol is a biotinylation reagentwith a primary hydroxyl (OH) that reacts with a variety of functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG6-hydrazide a PEGylated biotinylation reagent used for labeing glycoproteins, carbohydrate-containing compounds that have oxidizable sugars or aldehydes. Hydrazine moiety reacts with an aldehyde to form semi-permanent hydrazone bonds. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG12-hydrazide is an aqueous soluble biotinylation reagent that can used to label glycoproteins, carbohydrate-containing compounds that have oxidizable sugars or aldehydes. Hydrazine moiety reacts with an aldehyde to form semi-permanent hydrazone bonds. The hydrophilic PEG arm imparts water solubility that is transferred to the biotinylated molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-Lys (biotin-PEG4)-OH is a Lysine embedded biotin PEG linkers containing a carboxylic group and Fmoc-protected amine. Reaction of carboxylic with primary amino (-NH2) forms stable, irreversible amide bonds. The Fmoc group can be deprotected under basic condition to release the free amine which can be used for further conjugations. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-Lys (biotin-PEG12)-OH is a Lysine embedded biotinylation reagent containing a carboxylic group. Reaction of carboxylic with primary amino (-NH2) forms stable, irreversible amide bonds. The Fmoc group can be removed under basic condition to obtain the free amine which can be used for further conjugations. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
