Propargyl-PEG4-Maleimide has a propargyl group and a maleimide group. The propargyl group reacts with azide compounds or biomolecules under the catalyzation of copper in Click Chemistry reactions. The maleimide group enables the formation of a covalent bond with biomolecules containing a thiol group. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Methyltetrazine-PEG10-NH-Boc is a monodisperse PEG reagent containing methyltetrazine and a Boc protecting group. The hydrophilic PEG spacer arm improves water solubility and is transferrable to the labeled molecule, reducing aggregation of labeled proteins stored in solution. The Boc protecting group can be removed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Bis-PEG12-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids 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.
Hydroxy-PEG11-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.
2-Amino-1,3-bis(t-butoxycarbonylethoxy)propane is a PEG linker containing an amino group with two t-butyl esters. The amino group is reactive with carboxylic acids, activated NHS esters. The t-butyl protected carboxyl groups can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Trifluoroacetamidoethyl-SS-propionic NHS ester is a cleavable linker containing an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The disulfide bond can be cleaved under reduction conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
