Wako  194-18561 SCALEVIEW-S4 组织透明化试剂

本产品仅供研究使用。 请勿对人使用。
SCALEVIEW-S系列是用于ScaleS的试剂。 ScaleS是宫崎淳等人开发的组织清除方法。该方法使用的溶液主要是尿素。
通过浸入6种溶液(SCALEVIEW-S0,SCALEVIEW-S1,SCALEVIEW-S2,SCALEVIEW-S3,SCALEVIEW-S4,SCALEVIEW-SMt)使组织透明并调整RI,以进行显微镜观察。 使用该试剂,可以在1天之内使2mm的切片透明。
该方法可以制造出透明的组织,保持蛋白质的结构。 因此,有可能观察到表达荧光蛋白的组织,并在组织清除后用抗体和/或荧光染料标记。 它不仅适用于小鼠和大鼠的大脑,而且适用于人类染后的血液。 透明组织可以用电子显微镜或共聚焦显微镜观察。

SCALEVIEW-S series are reagent used for ScaleS. ScaleS is tissue clearing method developed by Dr. Atsushi Miyawaki etc. This method uses solutions with mainly urea. 
The tissue is made transparent and adjusted RI for microscopic observation by soaking in 6 kinds of solutions (SCALEVIEW-S0, SCALEVIEW-S1, SCALEVIEW-S2, SCALEVIEW-S3, SCALEVIEW-S4, SCALEVIEW-SMt). 2mm section can be made transparent in 1 day using the reagents.
The method can make a transparent tissue keeping the structure of proteins. Therefore it is possible to observe the tissue expressing fluorescent proteins, and to label by antibody and/or fluorescent dye after tissue clearing. It’s also applicable to not only mouse and rat brain but also human after dye. The transparent tissue can be observed for electric microscope or confocal microscope.
ScaleS is higher transparency than ScaleA2.

The original recipe reported by the Miyawaki team in 2011 termed Scale was an aqueous solution based on urea that limited because the transparency process itself can damage the structures under study.
The research team spent 5 years improving the effectiveness of the original recipe to overcome this critical challenge, and the result is ScaleS, (we called SCALEVIEW-S) a new technique with many practical applications. SCALEVIEW-S creates transparent brains with minimal tissue damage, that can handle both florescent and immunohistochemical labeling techniques, and is even effective in older animals.
The new technique creates transparent brain samples that can be stored in SCALEVIEW-S solution for more than a year without damage. Internal structures maintain their original shape and brains are firm enough to permit the micron-thick slicing necessary for more detailed analyses.


研究团队花了5年的时间来提高原始配方的有效性,以克服这一关键挑战,结果是ScaleS(我们称为SCALEVIEW-S)是一种具有许多实际应用的新技术。 SCALEVIEW-S可以创建透明的大脑,对组织的损害最小,可以处理荧光和免疫组织化学标记技术,甚至对年长的动物也有效。
