ATTO Dyes
ATTO-Dyes are available for labeling amino and thiolgroups.
ATTO reactive dyes cover the spectral region from 350 nm in the UV to
750 nm in the NIR.
The most commonly used amine reactive reagents are
N-hydroxysuccinimidyl(NHS)-esters. NHS-esters readily react with amine modified
oligonucleotides or amino groups by forming a chemically stable amide bond between the dye and the oligo.
For the labeling of thiol groups the most popular and commonly used reactive
reagents are maleimides. ATTO maleimides react with thiol groups to
form a stable thio-ether bond.
