Lipids & Polymers

Biotin-PEG-amine, MW 3,400 is a biotin PEGylation reagent. The biotin molecule has strong binding with avidin or streptavidin. The amine group is reactive with an activated NHS ester via formation of an amide linkage. Reagent grade, for research purpose.

DSPE-PEG-Amine, MW 5,000 is an amphiphilic PEG polymer with a hydrophobic DSPE chain and a terminal amine. DSPE- PEG is a widely used phospholipids-polymer in drug delivery applications. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic PEG chain increases overall water solubility and useful in drug delivery system. The free amine can react with activated NHS esters. Reagent grade, for research purpose.

t-Boc-N-amido-PEG-amine, MW 2,000 has a t-Boc protecing group and free amine which can be used in direct coupling with succinimidyl or PFP ester via amide bond formation. The t-Boc can be easily removed under acidic condition to produce a free primary amine. Reagent grade, for research purpose.

t-Boc-N-amido-PEG-amine, MW 3,400 is an amino PEGylation reagent with a t-Boc protecting group which can be removed under acidic conditions to form a free amine. Reagent grade, for research purpose.

t-Boc-N-amido-PEG-amine, MW 5,000 can react directly with any active ester, such as NHS and TFP, via formation of amide bond. Removal of the t-Boc can be accomplished with a strong acid to produce a free amine. Reagent grade, for research purpose.

bis-PEG4-endo-BCN is a homobifunctional click chemistry linker, PEG increase its aqueous solubility. The BCN group enable copper free click chemitry with azide-tagged molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DSPE-PEG-CH2COOH, MW 5,000 is a widely used phospholipid-PEG in drug delivery applications which allows hydrophobic drugs to be encapsulated. The -COOH functional group can react with primary amine to form a stable amide bond in the presence of EDC or HATU. Reagent grade, for research purpose.

Thiol-PEG-CH2COOH, MW 2,000 is a thiol functionalized polyPEG. The -COOH is reactive with primary amine in the presence of activator, such as EDC or HATU. The thiol moiety can react with many functional groups, such as maleimide, pyridyl disulfide, and transition metal. Reagent grade, for research purpose.

Thiol-PEG-CH2COOH, MW 3,400 is a maleimide reactive PEG polymer. The carboxylic acid can be reacted with primary amine in the presence of activator, such as EDC or HATU. The coupling between thiol and maleimide happens via formation of thioether bond. Reagent grade, for research purpose.
