PEG

Bis-Mal-Lysine-PEG4-acid is a PEG linker with two maleimide groups which can react with thiols from pH ranges of 6.5 to 7.5 to from a thiolester bond. The terminal carboxylic acid can react with primary amines in the presence of activators such as EDC and HATU to form stable amide bonds. The hydrophilic PEG linker increases the water solubility of a compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-Mal-Lysine-PEG4-TFP ester contains two malimide end groups which can react with thiol groups from pH 6.5 to 7.5 to form thiolester bonds. The TFP ester can react with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The hydrophilic PEG linker increases the compound's water solubility in aqueous environments. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DNP-PEG4-alcohol is a PEG linker containing a dinitrophenyl and a hydroxyl group. DNP is involved in biological applications such as participating in ion transport across membranes. The hydroxyl group can react to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound in aqueous environments. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Ald-Ph-PEG12-TFP ester is an amine reactive PEGreagent. The TFP ester can be reacted with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The benzaldehdye can react with aminooxy-bering molecules. The hydrophilic PEG chain increases the water solubility of compounds. Longer PEG chains have better water solubility properties relative to shorter PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Ald-Ph-PEG24-TFP ester is a long chain PEG TFP ester that is reactive with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The hydrophilic PEG chain increases the water solubility of compounds. Longer PEG chains have better water solubility properties relative to shorter PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG12-TFP ester is a biotinylation reagent that can react with amine (-NH2) compound to form stable amide bonds. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG24-TFP ester is a monodisperse PEGylated biotinylation reagent that can couple with amine(-NH2) compound to form stable amide bonds. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG9-NHS ester is a PEG linker containing an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-Acid is a non-activated building block and adds minimal spacer to modified molecules. In the presence of activators such as EDC or HATU, this reagent can be used to derivatize amine-containing molecules through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
