PEG

Methyltetrazine-PEG23-NH-Boc is a long PEG, aqueous soluble click chemistry reagent containing methyltetrazine and a Boc protecting group. Methyltetrazine enable fast click reaction with TCO (trans-cycloctene). The Boc protecting group can be removed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG4-NH-Boc is a PEG linker with a DBCO group and a Boc-protected amine. The DBCO can undergo copper-free Click Chemistry reactions with azides. The Boc protecting group can be removed under acidic conditions to further react. The hydrophilic PEG linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG12-bromide is a PEG linker containing a bromide group. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-Amido-PEG7-Tos is a PEG linker containing a tosyl group and Boc-protected amine group. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The Boc group can be deprotected under mild acidic conditions to form a free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(propanoic acid)-N-bis(m-PEG12) is a monodisperse PEG reagent containing a terminal carboxylic acid and two PEG chains. it can be used toconjugate with with primary amine-containing molecule in the presence of EDC or HATU. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Di(N-succinimidyl)adipate contains two NHS ester groups which can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
