A mouse embryonic fibroblast expressing mCherry-lamin A was spot-photobleached in the upper right corner of the nucleus using the FRAP module to study the dynamics of lamin A molecules. Time-lapse images were acquired using the epi-fluorescence illuminator. Image courtesy of Drs. Takeshi Shimi and Bob Goldman, Northwestern University Medical School
DMD模組
• 可同時多點進行光啟動(Photoactivation)實驗
有別於 FRAP 模組,DMD 模組可同時針對不同目標進行不同頻率的光活化實驗,尤其在 optogenetics 實驗,針對指定區域做光刺激後,觀察細胞中物質或蛋白質分布的變化。可選擇搭載不同類型的光源: LED 光源或 Laser 光源。
A mouse embryonic fibroblast co-expressing mCherry-tagged lamin A (red) and photo-activatable GFP-tagged lamin A was photo-converted (green) in the lower right region using the DMD module and 405 nm LED light. Time-lapse images were captured using the epi-fluorescence illuminator. By photoactivating a sub-population of the lamin proteins, one can observe their dynamics and subunit-exchange behavior.
