Fluorescent oligonucleotide imaging probes are synthetic DNA or RNA molecules
conjugated with visible-range fluorescent dyes that enable direct optical
detection of nucleic acid targets in microscopy, fluorescence hybridization
assays, and molecular detection workflows. These fluorescent probe conjugates
are widely used for target localization, fluorescence imaging, probe tracking,
and nucleic acid detection in cellular and analytical research applications.
At Bio-Synthesis, custom fluorescent oligonucleotide probes can be designed with
commonly used visible-range fluorophores for microscopy, hybridization assays,
and fluorescence-based detection workflows. Available dye categories include
green fluorescent dyes (~500–550 nm),
red/orange fluorescent dyes (~550–700 nm),
nucleic acid stain dyes, and
advanced high-performance fluorophores.
Fluorescent labeling can be configured at the 5′ end,
3′ end, or internal position depending on probe
architecture, hybridization performance, and imaging objectives.
Fluorescent probe technologies are frequently used together with broader
oligonucleotide imaging probe conjugate platforms
that enable optical reporters, near-infrared dyes, or other imaging labels to
be incorporated into nucleic acid probes for microscopy, molecular detection,
and spatial biology workflows.
The broader fluorescent probe field has been shaped by foundational work on
signal-generating hybridization probes, fluorescence resonance energy transfer,
and fluorescence imaging technologies for nucleic acid detection and microscopy
[1], [2]. Reviews covering
fluorescence imaging and nucleic acid probe chemistry remain useful references
when selecting fluorophores, optimizing probe placement, and balancing
brightness with spectral compatibility
[3], [4].
