PEG

Phenylmethyl N-(8-hydroxyoctyl)carbamate

N-bis(Methyltetrazine-PEG8)-N-(PEG8-acid) serves as a branched PEG linker consisting of a terminal carboxyl group for further conjugation and two methyltetrazine groups. The inverse-electron demand Diels-Alder cycloaddition reaction of TCO with tetrazines is the fastest bioorthogonal reaction with exceptional selectivity.

Azido-PEG-Fluor 647, MW 2,000 functions as a polyPEG entity which includes a bright-green Fluor 647 fluorophore optimal for use with the 633, 650 nm Argon laser and a free azide group reactive towards BCN, DBCO, alkyne via Click Chemistry. The PEG polymer increases the hydrophilicity of the labeled molecule.

ROX-PEG-Azide 6-isomer, MW 2,000 ROX-PEG is a polyPEG molecule possessing a passive reference dye for qPCR application and an a terminal azide for Click Chemistry with BCN, DBCO, alkyne. The PEG polymer chain improves the compound's overall water solubility.

Phenylmethyl N-(8-bromooctyl)carbamate

Cy3-PEG-CH2COOH, MW 2,000 is a fluorophore connected to a polyPEG and free carboxylic acid, which can react with amines in the presence of a coupling agent such as HATU. With this reagent, bright and photostable Cyanine3 can be attached to nearly any amine-bearing molecules.

Cy5-PEG-CH2COO-NHS, MW 2,000 contains Cy5, which is a bright red fluorescent dye with excitation and emission maxima at 651 nm and 670 nm respectively, and a free NHS ester that can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The PEG polymer increases the hydrophilicity of the conjugated molecule.

BP Fluor 647-PEG-CH2COOH, MW 2,000 is a polyPEG dye comprised of BP Fluor 647, which is a bright green-fluorescent dye optimal for use with the 633, 650 nm Argon laser. The dye is water soluble and pH-insensitive from pH 4 to pH 10. The dye has 4 sulfonate groups to make it very water soluble and less aggregating in the aqueous solution. The free carboxylic acid can react with amines in the presence of a coupling agent such as HATU. With this reagent, BP Fluor 647 can be attached to nearly any amine-bearing molecule.
