PEG

4-Arm PEG-NPC, MW 2,000 is a branched PEG linker containing a 4 terminal para-nitrophenyl carbonate (NPC) groups. NPC are highly reactive compounds that are usually treated with alcohols or amines to give either a new carbonate or a carbamate-linked compound depending on the nucleophile. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

4-Arm PEG-NPC, MW 5,000 is a branched PEG linker containing a 4 terminal para-nitrophenyl carbonate (NPC) groups. NPC are highly reactive compounds that are usually treated with alcohols or amines to give either a new carbonate or a carbamate-linked compound depending on the nucleophile. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

4-Arm PEG-NPC, MW 10,000 is a branched PEG linker containing a 4 terminal para-nitrophenyl carbonate (NPC) groups. NPC are highly reactive compounds that are usually treated with alcohols or amines to give either a new carbonate or a carbamate-linked compound depending on the nucleophile. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

4-Arm PEG-NPC, MW 20,000 is a branched PEG linker containing a 4 terminal para-nitrophenyl carbonate (NPC) groups. NPC are highly reactive compounds that are usually treated with alcohols or amines to give either a new carbonate or a carbamate-linked compound depending on the nucleophile.

LA-PEG-FITC, MW 1,000 is a green emitting fluorescent dye derivitative with excitation/emmission maximum 494/517 nm containing an azide group, which enables Click Chemistry. Lipoic acid contains two sulfur atoms (at C6 and C8) connected by a disulfide bond and is thus considered to be oxidized although either sulfur atom can exist in higher oxidation states. The hydophilic poly PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

[2-(Fmoc-amino)acetamido]methyl Acetate is a cleavable ADC linker with an Fmoc group and a terminal acetate group. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal acetate protecting group can be removed under acidic or basic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
