• Conjugation of SiR-NHS dye to proteins or peptides
• Conjugation of SiR-NHS dye to oligonucleotides or small molecules bearing a primary or secondary amine group

SiR-NHS is an amine reactive dye based on silicon rhodamine (SiR) (Ab: 652, Em: 674), designed for efficient conjugation to proteins, peptides or other amine-containing molecules.

Key features

• Ab: 652 nm, Em: 674 nm – far-red spectrum
• Emission in far-red minimizes phototoxicity and sample autofluorescence
• High extinction coefficient
• High photostability
• Compatible with widefield, confocal, STED and SIM microscopy
