The fluorescence emission spectrum of this Lissamine™ rhodamine B probe lies between those of tetramethylrhodamine and Texas Red probes. With peak absorption at 568 nm, Acetylene-Fluor 568 is readily excited by the 568 nm spectral line of the Ar - Kr mixed gas laser commonly used in many confocal laser-scanning microscopes. As many sulforhodamine probes, conjugates of Lissamine™ rhodamine B tend to exhibit higher fluorescence intensity than nonsulfonated rhodamine conjugates due to the higher negative charge of sulfonic groups compared to carboxyl groups. The fluorescence of the Lissamine™ rhodamine B conjugate as well as of many other rhodamine based probes is pH insensitive between 4 and 9, and exhibits excellent photostability.
