Product Description:

Carbonylacrylic PEG Rhodamine is one of Nanocs' thiol reactive fluorescent PEG derivatives that have a strong red fluorescent rhodamine fluorophore on its terminus. Similar to Maleimide, carbonylacrylic group reacts with thiol group quickly to form a stable thiol ether bond via so called ene-thiol Michael addition. Unlike maleimide-thiol adduct, the reaction between carbonylacrylic acid and thiol is non-reversible, and therefore the adduct is more stable for carbonylacrylic acid thiol conjuate. Carbonylacrylic acid reagents have been excellent reagents for site-specific Cysteine modification. Rhodamine, on the other hand, is a bright red fluorescent dye that can be easily traced by its strong fluorescent light. The excitation/emission wavelength of this fluorescent PEG is 547/576 nm.
