Description
Product Description
Key information: C-Laurdan is a polarity-sensitive lipid membrane probe.Used for: lipid raft imaging and cell membrane imaging.
Application: One and two-photon microscopy for membrane polarity.
Properties and Photophysical Data: C-laurdan carry a carboxylic group which can be partially ionized which contributes to its good water solubility and fast membrane incorporation. Two photon excitation spectra = 780 nm. One photon excitation and emission maxima (λ) are 348 nm and 423 nm, respectively; quantum yield = 0.43; extinction coefficient = 12,200 M-1cm-1.
