Rat Kangaroo Cell Tubulin

B-2E/C Bandpass Emission (Medium Bandwidth Excitation) Blue Set

Fluorescence emission intensity from a culture of rat kangaroo (PtK2) epithelial cells that were immunofluorescently labeled with primary anti-bovine alpha-tubulin mouse monoclonal antibodies followed by goat anti-mouse Fab fragments conjugated to Alexa Fluor 488. The visible light absorption maximum of Alexa Fluor 488 is 495 nanometers and the emission maximum occurs at 519 nanometers. Note the prominent staining of the intracellular microtubule network that extends throughout the cytoplasm. In addition, the specimen was simultaneously stained for the nuclear protein cdc6 (conjugated to Pacific Blue), and for F-actin with phalloidin conjugated to Alexa Fluor 568. Note the absence of signals from the blue (Pacific Blue) and red (Alexa Fluor 568) fluorophores, but the presence of intense green fluorescence from several of the more prominent tubulin cytoskeletal elements.
