SiR-actin has fluorescence, cell permeability, and high specificity for F-actin. Sir-atin staining for endogenous F-actin does not require gene manipulation or overexpression. Its emission in far-red light minimizes phototoxicity and the self fluorescence of the sample. SiR-actin is compatible with GFP and/or m-Cherry fluorescent proteins. It can be imaged using standard Cy5 filters. SiR-actin can be used for wide field of view, confocal, SIM or STED imaging of living cells and tissues. The number of probes allows for 50 to 200 staining experiments* (* Based on the following conditions: 0.5 1ml staining solution/0.5 1um probe concentration for staining experiments. The number of staining experiments can be further increased by reducing the volume or probe concentration).

 

SiR Action cell imaging

The imaging of SiR action is best done using standard Cy5 settings. After labeling, live cells can be immediately imaged without the need for washing steps. Optionally, a simple washing step includes replacing the labeled solution with fresh culture medium without probes, which typically improves the signal-to-noise ratio. If time elapses for imaging, it is recommended to keep the probe concentration equal to or lower than 100 nM throughout the experiment to obtain a constant signal and avoid probe interference with actin dynamics (reducing cell proliferation). If cleaning cells

Before imaging, the staining will last for several hours.

 

SiR-actin具有熒光性、細(xì)胞通透性和對(duì)F-actin的高度特異性。Sir-actin染色內(nèi)源性的F-actin不需要基因操作或過表達(dá)。它在遠(yuǎn)紅光中的發(fā)射最大限度地降低了光毒性和樣品的自身熒光。SiR-actin兼容GFP和/或m-cherry熒光蛋白質(zhì)。它可以用標(biāo)準(zhǔn)的Cy5濾鏡進(jìn)行成像。SiR-actin可用于活細(xì)胞和組織的寬視場(chǎng)、共聚焦、SIM或STED成像。探針數(shù)量允許50 - 200染色實(shí)驗(yàn)。*(*基于以下條件:0.5 - 1ml染色液/ 0.5 - 1um探針濃度的染色實(shí)驗(yàn)。染色實(shí)驗(yàn)的數(shù)量可以通過減少體積或探針濃度來進(jìn)一步增加)。
