PEG

4arm-PEG-Thiol, MW 2,000 is a thiol functional multiarm PEG polymer which is reactive with maleimide or disulfide molecules as well as transition metals like Au and Ag via a metal-thioalate complex. Reagent grade, for research use only.

4arm-PEG-Thiol, MW 5,000 is a thiol functional multiarm PEG polymer which is reactive with maleimide or disulfide molecules as well as transition metals like Au and Ag via a metal-thioalate complex. Reagent grade, for research use only.

m-PEG-thiol, MW 1,000 is PEG polymer with a terminal thiol. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research use only.

N-(Azido-PEG1)-N-bis(PEG2-Methyltetrazine-propylamine) is a branched click chemistry reagent with an azide group and two terminal Methyltetrazine groups. The azide group enables Click Chemistry with BCN, DBCO, and alkynes. Methyltetrazine enables a fast click reaction with TCO (trans-cycloctene). Reagent grade, for research use only.

N-(Methyltetrazine-PEG4)-N-Biotin-PEG4-acid is a branched biotinylation tool that enables copper-free click chemistry with a carboxyic acid group and a TCO reactive reagent. The inverse-electron demand Diels-Alder cycloaddition reaction of TCO with tetrazines is the fastest bioorthogonal reaction with exceptional selectivity. Reagent grade, for research use only.

N-(Methyltetrazine-PEG4)-N-Biotin-PEG4-NHS is a branched biotinylation tool that enables copper-free click chemistry with an NHS ester group and a TCO reactive reagent. The inverse-electron demand Diels-Alder cycloaddition reaction of TCO with tetrazines is the fastest bioorthogonal reaction with exceptional selectivity. The NHS group reacts specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds. Reagent grade, for research use only.

4arm-PEG-ACRL, MW 5,000 is a PEG polymer with acrylate at each terminal of the four arms connected to one pentaerythritol core. The acrylate group can be used in radical polymerization or thiol-ene reactions. Reagent grade, for research use only.

Acrylate-PEG-acrylate, MW 1,000 is a di-acrylate PEG polymer. This compound is very useful as a crosslinking agent due to simple polymerization of the vinyl groups at both ends. The PEG chain helps with water solublity and flexibilty of the crosslinking agent. Reagent grade, for research use only.

Acrylate-PEG-NH2, MW 1,000 is a functionalized PEG containing both acrylate and amine groups. The amine reacts with NHS esters or carboxylic acids in the presence of HATU or EDC. The acrylate group can be used for radical or UV initiated polymerization or thiol-ene reactions via Michael Addition. Reagent grade, for research use only.
