N-Propargylmaleimide efficiently adds a terminal alkyne group to antibodies, cysteine-containing peptides, or other thiol-containing molecules. The maleimide group specifically reacts with reduced thiols at pH 6.5-7.5, forming stable thioether bonds. The short spacer arm minimizes added mass. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Phthalimidooxy-PEG4-NHS ester is a protected aminooxy compound with an NHS ester-linked to a Phthalimide moiety via four discrete PEG units. It enables the installation of a hydrophilic, protected aminooxy group on peptides, proteins, small molecules, and amine-functionalized surfaces. Upon deprotection, the aminooxy group forms stable oxime bonds with aldehydes and ketones. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG13-DSPE functions as a PEG linker containing DSPE and methoxy moieties. The DSPE-PEGs have been FDA approved for medical applications. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic PEG linker enhances the water solubility of the overall compound allowing for the delivery of the drug. Reagent grade, for research purpose.
