Fluorescent microtubules break up under illumination

چکیده
We have synthesized three new fluorescent analogues of tubulin, using fluorescein or rhodamine groups attached to N-hydroxy-succinimidyl esters, and have partially characterized the properties of these analogues. We have also further characterized the tubulin derivatized with dichlorotriazinyl-aminofluorescein that has previously been used in this and other laboratories. Our results show that all four analogues assemble into microtubules which break up when exposed to light of the wavelengths that excite fluorescence. This sensitivity places severe constraints on the use of these analogues in studies of microtubule dynamics.

EFFECTS OF SALT AND IRRADIANCE STRESS ON PHOTOSYNTHETIC PIGMENTS AND PROTEINS IN DUNALIELLA SALINA TEODORESCO
The aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in Dunaliella salina Teod. The algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 M NaCl under three illumination regimens [4500 (control), 9000 and 11000 Lux]. The results showed that most electrophoresis protein bands were separa...
متن کاملNonlinear structured-illumination microscopy with a photoswitchable protein reveals cellular structures at 50-nm resolution.
Using ultralow light intensities that are well suited for investigating biological samples, we demonstrate whole-cell superresolution imaging by nonlinear structured-illumination microscopy. Structured-illumination microscopy can increase the spatial resolution of a wide-field light microscope by a factor of two, with greater resolution extension possible if the emission rate of the sample resp...
متن کاملDynamics and organization of cortical microtubules as revealed by superresolution structured illumination microscopy.
Plants employ acentrosomal mechanisms to organize cortical microtubule arrays essential for cell growth and differentiation. Using structured illumination microscopy (SIM) adopted for the optimal documentation of Arabidopsis (Arabidopsis thaliana) hypocotyl epidermal cells, dynamic cortical microtubules labeled with green fluorescent protein fused to the microtubule-binding domain of the mammal...
متن کاملMechanism and dynamics of breakage of fluorescent microtubules.
The breakage of fluorescence-labeled microtubules under irradiation of excitation light is found in our experiments. Its mechanism is studied. The results indicate that free radicals are the main reason for the photosensitive breakage. Furthermore, the mechanical properties of the microtubules are probed with a dual-optical tweezers system. It is found that the fluorescence-labeled microtubules...
متن کاملModified Couple Stress Theory for Vibration of Embedded Bioliquid-Filled Microtubules under Walking a Motor Protein Including Surface Effects
Microtubules (MTs) are fibrous and tube-like cell substructures exist in cytoplasm of cells which play a vital role in many cellular processes. Surface effects on the vibration of bioliquid MTs surrounded by cytoplasm is investigated in this study. The emphasis is placed on the effect of the motor protein motion on the MTs. The MT is modeled as an orthotropic beam and the surrounded cytoplasm i...
