DBCO-NHCO-PEG5-NHS ester is a PEG linker containing NHS ester that is able to react specifically and efficiently with primary amines such as the side chain of lysine residues or aminosilane-coated surfaces at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and can also provide a long and flexible connection that minimizes steric hindrance during ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Recommended Use: Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage: This kit is stable for 2 years after the date of shipment.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
Propargyl-PEG4-(CH2)3-CO2H is a linker containing a propargyl group at one end and a carboxylic acid at the other end. The carboxylic acid reacts with amine groups in the presence of activators (EDC or HATU). Under the catalyzation of copper, the propargyl group forms linkage with azide group of biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
