Biotinylation reagent with maleimide group. React specifically with reduced thiols (sulfhydryl groups), such as cysteine-containing peptides, at pH 6.5-7.5.

Biotinylation reagent with N-hydroxysuccinimide, and very long (12 PEG) spacer. The NHS group reacts with the e-amino group on the N-terminus of proteins, and other primary amines. A coupling agent such as EDC is required to activate the reaction.

m-PEG4-acid is a PEG linker containing a terminal carboxylic acid. 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. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bromoacetamido-PEG2-NHS ester is a PEG linker containing a bromide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose.

Bromoacetamido-PEG3-azide is a crosslinking reagentwith 3 PEG units. The azide group enables Click Chemistry. Bromoacetamido is a very reactive group for nucleophilic substitution. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-Maleimide is a sulfhydryl reactive reagent containing a maleimide group and a DBCO moiety. Maleimide group specifically and efficiently reacts with thiols to form thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety into cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG4-Maleimide is PEG linker containing a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
