Fluorescent Dyes
The CHROMIS product line is a selection of the newest fluorescent labels available today. Dye structures were carefully chosen to provide top-notch brightness performances, improving bioanalytical assays to the highest level.
Eight different basic structures with precise absorption/emission maxima were selected to cover the full working range of wavelength, starting from 400 nm up to 850 nm. To meet the need of labeling the broadest range of target molecules each fluorescent compound is available with many different reactive moieties (e.g. the commonly used amine reactive and thiol reactive groups) while retaining the photophysical features of the parent dye. Furthermore, a completely new level of chemistry has been developed to provide the same fluorescent label with different charge values (anionic, cationic, zwitterionic and neutral). The ability to carefully tune this parameter is a critical aspect for many biological techniques, such as electrophoresis and related methods.
The following example is a schematic representation of the products subdivision:
It is thus very easy to find the ideal product among the CHROMIS series starting from the desired absorption/emission peak maximum and subsequently decide both the reactivity and charge properties.
With more than 60 different ready-to-use fluorescent labels and the chance to combine them with more than 40 among crosslinkers and biotinylating reagents CRB's Chromis dyes can drastically expand your bioconjugation possibilities.
CRB offers also ready-to-use kits for protein labeling with fluorescent dyes.
