Description

mPEG-DBCO reacts with molecules containing azide groups (N3) in a Copper-free Click Chemistry. DBCO stands for dibenzocyclooctyne. DBCO has very high reaction selectivity toward azide, enabling its use in modifying biomolecules including peptide, protein, enzyme, live cells, whole organisms etc. At physiological temperature and pH ranges, DBCO does not react with amine or hydroxyl, and DBCO also reacts with azide much faster than with free thiol. DBCO synonyms: ADIBO (Azadibenzocyclooctyne) or DIBAC (Dibenzoazacyclooctyne). DBCO is the most common cyclooctyne.

Properties

Molecular weight: MW of PEG was measured by MALDI-MS or GPC. PDI (polydispersity index) of our linear PEG is 1.02-1.05 with very narrow MW distribution. The number of repeating ethylene oxide units (CH2CH2O) or the degree of polymerization is calculated dividing the PEG MW by 44 (44 is the molecular mass of one repeating unit).

Solubility: Soluble in water and aqueous buffer, chloroform, methylene chloride, DMF, DMSO, and less soluble in alcohol, toluene. Not soluble in ether.

Density: PEG density is approximately 1.125 g/mL

Physical form: PEG products generally appear as white or off-white powder, and for very low MW linear PEG such as MW 1k or less, it may appear as wax-like, semi-solid material due to the low MW and the type of functional groups.

Storage condition: PEG product shall be stored in the original form as received in a freezer at -20C or lower for long term storage. Stock solution of PEG reagents that do not contain oxygen or moisture sensitive functional groups may be temporarily stored in a refrigerator or ambient temperature for multiple days. Stock solution should avoid repeated freeze-and-thaw cycles. See Documents section for detailed storage and handling conditions.
