APDye Fluor 647 NHS Ester (Alexa Fluor® 647 analog, CAS: 407627-60-5) is a bright, far-red fluorescent dye perfect for 633 nm and 647 nm lasers. It stands out because it reduces autofluorescence in biological specimens, unlike other dyes.
Key Features:
- Far-Red Fluorescence: Optimized for minimal background interference, giving clear and vivid results.
- Efficient Labeling: The NHS ester group binds directly to primary amines on proteins, peptides, and oligonucleotides.
- Superior Brightness: Label proteins at high molar ratios without self-quenching, resulting in brighter, more sensitive detection.
- Versatile Analog: Works like Cy5, Alexa Fluor® 647, CF® 647, and other Cyanine5-based dyes, offering broad compatibility with various bioassays.
Applications:
- Protein and Antibody Labeling: Use it for direct labeling, enhancing the detection of low-abundance targets.
- Oligonucleotide Labeling: Ideal for amine-modified oligonucleotides in diagnostics and research.
- Bioconjugation: Engage it in click chemistry or direct conjugation for reliable and stable fluorescence.
APDye Fluor 647 NHS Ester helps you achieve bright, stable signals in imaging and flow cytometry, making it an excellent choice for your fluorescence needs.
