Leica AM TIRF MC 光路設計與 TIRF 技術原理 |
|
TIRF (Total Internal Reflection
Fluorescence)
利用雷射光入射角度達到全反射時,在介質表面形成的漸逝波(Evanescent
Wave)做為激發螢光的能量來源,由於漸逝波的深度僅於表面 70~300 nm,較深的螢光物質便不會被激發,只有極靠近全反射面的樣本區域會產生螢光反射,大大降低了背景光雜訊干擾觀測標的,故此項技術廣泛應用於細胞表面物質的動態觀察。因此可觀察表面螢光表現而不受干擾
( 例如細胞膜內外的動態觀察 ),為提高 Z
軸解析度之一項技術. |
|
全內反射螢光顯微術 (
TIRFM) 是探索細胞基底的淺層接觸區域內的細胞生命活動現象的有效光學探測方法.,如細胞膜內蛋白質的動力學過程,基底附近的細胞骨架,細胞運動…等,
可應用於即時觀察單一肌漿球蛋白分子的運動、單一蛋白分子對之間的螢光共振能量轉移
(FRET),…..酶的轉譯,聚合物內單個分子的結構變化,
等離子體膜附近的神經分泌腺的顆粒運動.

TIRF MC,只要輕鬆按下滑鼠,便可以自動校正雷射光全反射角度,並可選擇四種不同的雷射入射方向,不再只能得到單一方向的 TIRF 影像,領先突破現有的研究範疇! |
 |
|
因為 Leica AM TIRF MC 可以簡易的得到超高解析的全反射螢光現象, 讓你專注於樣品研究,
而不是浪費時間在調整雷射或光徑角度.
Leica AM TIRF MC 的獨家設計, 雷射光入射角度是全自動調整, 並可精確的控制
全反射的漸逝波深度 ( evanescent wave ),
可讓你一層一層觀察全反射螢光斷面影像, 可經確的探討細胞膜內外的動態螢光影像, 突破極俱研究價值的使用效益.
|
 |
|
Leica AM TIRF MC 系統可控制全反射漸逝波(evanescent
wave)深度,不同雷射波長,也可保持固定的漸逝波深度,更能增加實驗結果的可信度及再現性。漸逝波深度經由軟體可自由調整,得到不同漸逝波深度下的全反射螢光影像,提供了更多可能性的研究方向。
Leica AM TIRF MC 所追求的是創造出使用人員的實用效益.
讓使用者能快速與精確的得到研究成果.

TIRF Membrane Research
View dynamic structures and events
-
Research of molecular interactions at cell
membranes, of proteins and receptors involved in transport
mechanisms, requires fast switching of the excitation
wavelength. With Leica Multi-Color TIRF, wavelengths are
switched in a few ms without alteration of the penetration
depth. The system’s fast control and high image recording
rate of up to 30 frames per second is also an advantage
for FRET analysis. Using the new FRET wizard, experiments
can be conducted with ease and fully evaluated
automatically.
-
If alternating wavelengths are required in
the widefield light path of the TIRF module, Leica’s fast
filter wheels can be used. Switching times of
approximately 30–50 ms are easily achievable
|
 |
|
TIRF Single Molecule
Explore the world of single molecules
-
With the Leica TIRF system it is easy to
image single molecules close to the cell membrane.
-
Typically, a powerful objective’s
resolving power in the z axis is physically limited to
approximately 400–500 nm by the wavelength of the light
used. This physical restriction is eliminated by the high
accuracy of the TIRF excitation of ~ 100 nm in the z axis.
Even interactions of single molecules, the kinetics or
co-localization of molecules can be visualized and
measured with Leica’s highly sensitive TIRF system.
-
The constant penetration depth when
switching the laser lines is a key prerequisite for using
multiple fluorophores. Due to the excellent signalto-noise
ratio, the entire dynamic range of this high-performance
camera can be exploited. Even with weak fluorescent
signals, the EMCCD camera provides highest resolution
images while ensuring the uncompromising sensitivity
essential for the gentle treatment of light-sensitive
specimens
|
  |
|
TIRF Vesicle Transport
High resolution and minimum light stress
-
Due to strong background fluorescence,
vesicle transport studies require an optimum
signal-to-noise ratio. At the same time, stability for
experiments lasting several hours or days is a must.
Vesicle transport experiments are made simple with the
Leica AM TIRF MC.
-
With the addition of Leica’s special
climate chamber to the TIRF system, temperature and CO 2
levels remain constant.
The Leica AF6000 multidimensional fluorescence
workstation with intelligent application software and
hardware provides accurate results. For brilliant
photographs of vesicle transport investigations, a
high-sensitive and high-speed EMCCD camera can be used.
