Ms-PEG13-t-butyl ester is a PEG linker containing a mesyl group and a t-butyl ester moiety. The mesyl group is a good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions and allowing for the carboxylic acid to react with primary amines in the presence of activators such as EDC and HATU. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
N-(Acid-PEG2)-N-bis(PEG3-azide) is a PEG linker containing two azide groups and a carboxylic acid. The azide groups enable PEGylation via Click Chemistry. 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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
N-(t-butyl ester-PEG2)-N-bis(PEG3-azide) is a branched conjugation reagent The azide groups is very reactive with alkyne such as DBCO, BCN and propargyl reagnet via Click Chemistry. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases the hydrophilic properties of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
DBCO-PEG1-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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
DBCO-PEG9-NH-Boc is a Boc-protected click chemistry 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. PEG linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
DBCO-PEG1-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Diketone-PEG12-DBCO is a class of PEG linkers containing a diketone group and a DBCO group which can react with azides via a copper-free Click Chemistry reaction to form a stable triazole. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Fmoc-PEG24-NHS ester is a PEG linker containing an Fmoc-protected amine and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. 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.
