PEG

1, 1, 1-Trifluoroethyl-PEG4-Amine is a PEG linker with a trifluoroethyl and amine moiety. The amine can react with carboxylic acids, activated NHS esters and other carbonyl compounds. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG5-CH2CO2H is an alkyne linker with a carboxylic acid. The carboxylic acid can react with primary amines to form stable amide bonds; activator (e.g. EDC, or HATU) is needed. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

PEG5-(CH2CO2H)2 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.

t-Boc-Aminooxy-PEG3-amine is a Boc-protected aminooxy molecule. The amine (NH2) group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The Boc-aminooxy can be deprotected under mild acidic conditions and then reacts with an aldehyde to form a linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-aminooxy-PEG2-propargyl is a click chemistry crosslinker. The propargyl group is reactive with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to yield a stable triazole linkage. t-Boc-aminooxy can be deprotected under mild acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG20-azide is a long chain, monodisperse PEG linker consisting of two azide groups. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

1,1,1-Trifluoroethyl-PEG4-aminooxy is a fluorine containing PEG molecule. The aminooxy group can be used in bioconjugation and It reacts with an aldehyde to form an oxime bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

S-acetyl-PEG4-propargyl is a PEG linker containing a sulfur acetyl group and a propargyl moiety. The sulfur acetyl group can be deprotected to produce a thiol compound. 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 hydrophilic PEG linker increases the water solubility of the compounds in the aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tr-PEG9 is a PEG linker with a trityl protecting group and a terminal hydroxyl group. The trityl protecting group is used for primary alcohols and can be deprotected under mild acidic conditions. The hydroxyl group can react to further derivatize the compound. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose.
