Lipids & Polymers

MPEG-GAS, MW 1,000 is a polyPEG linker with a terminal succinimidyl glutaramide group. The succinimidyl glutaramide group is a good leaving group and commonly reacts with amine nucleophiles at pH 7 to 9. The hydrophilic polyPEG spacer increases solubility in aqueous media. Reagent grade, for research use only.

OPSS-PEG-NHS, MW 1,000 is a polyPEG liner that contains a orthopyridyl disulfide (OPSS) group and a terminal NHS group. The terminal OPSS group can selectively react with a free thiol, SH, sulfhydryl or mercapto. The NHS group can participate in reactions with primary amine groups to form amide bonds. The hydrophilic polyPEG chain increases the water solubility of the compound in aqueous environments. Reagent grade, for research use only.

OPSS-PEG-NHS, MW 10,000 is a polyPEG liner that contains a orthopyridyl disulfide (OPSS) group and a terminal NHS group. The terminal OPSS group can selectively react with free thiol, SH, sulfhydryl or mercapto. The NHS group can participate in reactions with primary amine groups to form amide bonds. The hydrophilic polyPEG chain increases the water solubility of the compound in aqueous environments. Reagent grade, for research use only.

RhB-PEG-NHS, MW 2,000 is a linear polyPEG with a terminal red fluorescent probe (rhodamine) for labeling and NHS ester moiety. The hydrophilic polyPEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research use only.

RhB-PEG-NHS, MW 5,000 is a linear polyPEG with a terminal red fluorescent probe (rhodamine) for labeling and NHS ester moiety. The hydrophilic polyPEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research use only.

8-arm PEG-ALK, MW 10,000 is a branched crosslinker with eight terminal propargyl groups. The propargyl groups can react with azide compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. Reagent grade, for research use only.

8-arm PEG-ALK, MW 40,000 is a branched crosslinker with eight terminal propargyl groups. The propargyl groups can react with azide compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. Reagent grade, for research use only.

Alkyne-pGlu, MW 20,000 is a chemical reagent containing a terminal alkyne ligated to a poly(glutamic acid) peptide. The terminal alkyne is commonly used in copper (I) click chemistry to form stable triazoles with azides. Poly(glutamic acid) is a peptide polymer which is commonly used in cosmetics and drug delivery. The carboxylic acid in each amino acid monomer is capable of reacting with nucleophiles such as amines or thiols to form stable, water soluble bonds.

Mal-PEG-Amine, MW 1,000 is a polyPEG linker containing a maleimide group and an amine group. The hydrophilic polyPEG spacer increases solubility in aqueous media. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The maleimide group will react with a thiol group to form a covalent bond. Reagent grade, for research use only.
