DBCO-PEG4-NHS Ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. 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 provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Product Info
Description
FluoroDye™ DNA Fluorescent Loading Dye is a ready-to-use 6X DNA loading dye designed for fast qualitative electrophoresis analysis. Containing sensitive fluorescent dye with high specific affinity towards double stranded DNA (dsDNA), the FluoroDye™ Fluorescent DNA Loading Dye has negligible background and renders destaining process unnecessary. The FluoroDye™ DNA Fluorescent Loading Dye allows the user to immediately visualize electrophoresis result upon completion or to monitor the electrophoresis in real time. FluoroDye™ DNA Fluorescent Loading Dye is compatible with both the conventional UV gel-illuminating system as well as the less harmful long wavelength blue light illumination system. FluoroDye™ emission as bound to dsDNA is 522 nm, while its excitation peaks are at 270, 370 and 497 nm.
Features:
Excellent for premix with DNA samples
Sensitivity: 0.14 ng (DNA)
A safer alternative to EtBr
Compatibility: suitable to blue or UV light
Increased cloning efficiency (blue light)
Composition
FluoroDye™ DNA Fluorescent Loading Dye is stored in 6X concentration in 60% glycerol and buffered with Tris-HCl and EDTA, containing Bromophenol blue, Xylene cyanol FF and Orange G as tracking dyes.
Storage
Protected from light -20°C for 24 months
