Fluorescent Dopamine Neurotransmitter Ligand, labeled with Dansyl

Descrição detalhada : This fluorescent labeled catecholamine neurotransmitter analog of dopamine (Product Name: DnsylD-1), with dansyl attached by a 5-carbon spacer arm to dopamine, provides a unique pharmacological tool. DnsylD-1 is a stable, receptor selective and high affinity pharmacological ligand that can be detected by fluorescent microscopy and FLIPR devices. Unlike recently reported synthesized fluorescent neurotransmitter analogs, DnsylD-1 contains the entire native dopamine structural moiety attached with the 5-carbon polylinker to the small fluorescence label dansyl. This structural modification minimizes steric hindrance, making DnsylD-1 an effective reagent for dopamine ligand binding and transporter uptake assays at namomolar concentrations. A large stokes shift between excitation and emission maxima (Ex:Em, 313:515 nm) of DnsylD-1 provides high signal to noise detection with minimal autofluorescence. The dansyl moiety also changes spectral characteristics on intermolecular contact, facilitating biophysical characterization of ligand-receptor interaction. DnsylD-1 is a suitable substitute for radioactive ligand.
