N-(Propargyl-PEG2)-N-Boc-PEG3-t-butyl ester is a click chemistry branched linker. The propargyl group can react with azide-bearing compounds through Click Chemistry, the t-butyl protected carboxyl group can also be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG4)-N-bis(PEG4-t-butyl ester) is a 3-arm PEG reagentr consisting of a terminal azide group and two t-butyl esters. The azide group enables PEGylation via Click Chemistry. The t-buty ester groups can be hydrolyzed under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG4)-N-bis(PEG4-acid) is a branched click chemistry reagent with a terminal azide group and two terminal carboxylic acids. The azide group enables Click Chemistry with alkyne. The terminal carboxylic acids can react with primary amino groups in the presence of activators (e.g. EDC, HATU ). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-amido-PEG4-NHS ester is a PEG linker containing a Boc-protected amine group and an NHS ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The protected amine can be deprotected by acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-aminooxy-PEG6-propargyl is a bifunctional linker molecule. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected aminooxy can be deprotected under mild acidic conditions and then can react with an aldehyde.. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-aminooxy-PEG5-propargyl is a click crosslinker. Propargyl group is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. T-Boc-aminooxy can be converted to free aminooxy under mild acidic conditions and then can react with an aldehyde or ketone. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG3)-N-bis(PEG1-t-butyl ester) is developed as a branched PEG linker with a terminal azide group and two t-butyl esters. The azide group enables PEGylation via Click Chemistry. The t-butyl protected carboxyl groups can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG4)-N-Boc-PEG3-t-butyl ester enables Click Chemistry with alkyne such as DBCO , BCN or Propargyl reagent. Boc and the t-butyl protected carboxyl group can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Amino-PEG5)-N-bis(PEG4-acid) is a aqueous soluble PEG linker with an amino group with two terminal carboxylic acids. The amino group is reactive with carboxylic acids, activated NHS esters. 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.
