Fluorescent dye that is water-soluble and forms stable thioether bond with free thiol groups. Protein conjugates prepared with Fluorescent Dye 350-I Maleimide are bright with fluorescence unaffected by pH in the physiological range (pH 4-10).

Fluorescent dye that is water-soluble and forms stable Schiff Base with carbonyl group. Protein conjugates prepared with Fluorescent Dye 350-I Hydrazide are bright with fluorescence unaffected by pH in the physiological range (pH 4-10).

Fluorescent dye that is water-soluble and forms stable peptide bond with protein amino groups. Protein conjugates prepared with Fluorescent Dye 405-I Succinimidyl Ester are bright with fluorescence unaffected by pH in the physiological range (pH 4-10). Fluorescent Dye 405-I Succinimidyl Ester labeled conjugates are excellent violet laser reagents for flow cytometry research.

Fluorescent dye that is water-soluble and forms stable peptide bond with protein amino groups. Fluorescent Dye 488-I Succinimidyl Ester conjugates are significantly brighter than fluorescein conjugates and much more photostable. Additionally, the fluorescence of Fluorescent Dye 488-I Succinimidyl Ester is not affected by pH between 4-10. Compared to Alexa Fluor 488, Fluorescent Dye 488-I Succinimidyl Ester of single isomer has much hihger purity, bringing better performance consistancy from batch to batch.

Fluorescent dye that is water-soluble and forms stable peptide bond with protein amino groups.

Fluorescent dye that is water-soluble and forms stable peptide bond with protein amino groups. Compared with Cy3 conjugates, those of Fluorescent Dye 555-I Succinimidyl Ester are slightly red-shifted, resulting in an optimal match to filters designed for Cy3 dyes in accompany with improved photostability. Besides, their fluorescence is pH-independent from pH 3 to 11.
