| Targets |
Primary amine groups on proteins, peptides, and other amine-containing molecules. The BDP-581/591 dye also reacts with ROS, particularly lipid hydroperoxides and peroxyl radicals, making it useful for detecting oxidative stress.
|
|---|---|
| ln Vitro |
BDP-581/591 NHS ester exhibits absorption at 585 nm and emission at 594 nm (Ex=585 nm, Em=594 nm). It has a relatively long fluorescence lifetime (3-5 ns) and a two-photon excitation cross-section for deep-tissue imaging. The dye's fluorescence changes upon reaction with ROS.
|
| ln Vivo |
Not applicable; this is a labeling reagent for research use. Fluorescently labeled proteins conjugated with BDP-581/591 can be used for in vivo imaging of inflammation, cancer, or oxidative stress when administered to animals.
|
| Enzyme Assay |
The NHS ester (1-10 mM in anhydrous DMSO or DMF) is added to protein (1-10 mg/mL) in labeling buffer (0.1 M sodium bicarbonate, pH 8.3-8.5) at 10-50:1 molar ratio (dye:protein). Incubate at room temperature for 1-2 hours. Free dye is removed by desalting or dialysis.
|
| Cell Assay |
Labeled proteins (0.1-10 microg/mL) are added to live cells for 30-60 minutes at 37degC. Intracellular ROS levels can be measured by monitoring fluorescence changes. Alternatively, cells are treated with H2O2 or other ROS inducers, and fluorescence is measured on a plate reader (λex=585 nm, λem=594 nm).
|
| Animal Protocol |
Not applicable for free NHS ester. BDP-581/591-labeled Annexin V or other apoptosis markers are injected intravenously (50-200 microg per mouse) to detect ROS-related cell death in disease models (e.g., ischemia-reperfusion injury, inflammation). Imaging is performed 1-4 hours post-injection.
|
| ADME/Pharmacokinetics |
Not applicable for free NHS ester. The BDP-581/591 dye has excellent photostability and serum stability. Labeled proteins have half-lives of 6 hours to 10 days depending on the protein and conjugation site. The dye is non-toxic at labeling concentrations.
|
| Toxicity/Toxicokinetics |
No toxicity; BDP-581/591 NHS ester is used at low concentrations for labeling purposes and has no known acute toxicity. The dye is stable under normal handling conditions. Avoid prolonged light exposure to prevent photobleaching.
|
| Additional Infomation |
BDP-581/591 NHS ester is for research use only, not FDA-approved. It is widely used for ROS detection in live-cell imaging, flow cytometry, and two-photon microscopy. It is also used for fluorescence polarization analysis and protein-protein interaction studies.
