EviTag Quantum Dot Conjugates

EviTag® based quantum dot conjugates, cutting-edge fluorophores ready for lab bench use. EviTags are biocompatible quantum dots with performance characteristics far exceeding traditional organic chemical and protein fluorophores.

EviTags Shine Brighter and Longer
Bright fluorescence - Researchers have used their intense fluorescence to track individual molecules.     Highly photo-resistant - EviTags have fluorescence lifetimes of up to a week under illumination, with little or no photobleaching.     Low cytotoxicity - Their proprietary coatings make EviTags biologically inert. Perform in-vivo and in-vitro experiments that last weeks.	Co-staining in NIH 3T3 fibroblasts, with Fort Orange EviTags (600nm, pseudo-red), FITC and DAPI.
EviTags are Superior for Color Multiplexing
Single excitation source possible - Essentially every color of quantum dot can be excited by the same source, just use a shorter wavelength light source (blue or UV preferable) than your EviTags' emissions.     Variety of colors - Since Quantum dot emission frequency is size-dependent, EviTags can come in any color. Our current offering ranges from Lake Placid Blue (490 nm) to Maple Red-Orange (620 nm).     Sensitive and precise - Due to their large Stokes Shift and sharp emission spectra, our conjugates have high signal intensity with minimal background interference.     Highly Specific - highly specfic F(ab')2 fagements, adsorbed to commonly cross-reactive species, increase signal while decreasing background.     Easily excitable - Their broad excitation spectra allow the use of existing excitation sources, making imaging easier.
