EDANS sodium

SKU: orb1297713

Description

EDANS sodium salt is a fluorescent donor dye widely used to construct FRET-based nucleic acid probes, particularly for real-time PCR assays. Its applications extend to in vitro studies of enzyme kinetics, such as monitoring nuclease and protease activity, and in the development of molecular beacons for pathogen detection.

Bioactivity

−

In Vitro

EDANS sodium salt is much more water-soluble than EDANS acid. It is one of the most popular donors for developing FRET-based protease substrates and nucleic acid probes. EDANS is often paired with DABSYL or DABCYL in FRET-based probes. Its fluorescence is environment sensitive.

Cell Research

Instructions I. Reagent preparation: 1. Preparation of master solution and working solution: Dissolve in appropriate solvent (such as water, PBS), the concentration is usually in the range of 10-100 µM, and the specific concentration depends on the experimental needs. 2. Probe synthesis: When developing FRET probes, EDANS can be used as a donor to pair with a specific acceptor dye. The synthesis of the probe is usually completed by connecting EDANS to the target DNA or RNA sequence. II. Operation steps 1. PCR reaction: 1) Probe design: FRET-based probes usually contain donors (EDANS) and acceptor dyes (such as TAMRA, BHQ, etc.). The design of the probe must ensure that the distance between EDANS and the acceptor is appropriate to optimize energy transfer. 2) PCR reaction: Add the synthesized FRET probe to the real-time PCR reaction and react with DNA polymerase, dNTPs, template DNA and primers. The probe will bind to the specific target sequence during PCR amplification. 3. Fluorescence detection: During the PCR process, the donor dye (EDANS) transfers energy to the acceptor dye through excitation, resulting in changes in the fluorescence signal, and real-time monitoring of the progress of the PCR reaction. 4. Data analysis: Use a real-time PCR instrument (such as a fluorescence quantitative PCR instrument) to monitor changes in the fluorescence signal and calculate the concentration of the target DNA or RNA. Notes: 1. Probe optimization: Selecting the right FRET pair (donor and acceptor) is the key to success, ensuring that their spectral properties are complementary to achieve optimal energy transfer. 2. Solubility: EDANS sodium has good solubility, but when using it, avoid excessive exposure to strong light to prevent fluorescence bleaching.
