    • The present invention provides a method to clarify and contrast stain intact biological tissue samples for microscopic analysis. Biological specimens are prepared for visual analysis by depigmenting specimen, staining the specimen non-specifically with fluorescent dye, and equilibrating the depigmented, non-specifically stained specimen in a clearing solution, wherein the refractive index of the clearing solution approximates that of the specimen. Visual analysis of the specimen can include, for example, determination of distribution, quantity and size of foreign material in the biological specimen. Also, the morphology of tissue surrounding foreign material can be assessed.
    • 本发明提供了一种澄清和对比染色完整的生物组织样品用于显微镜分析的方法。 制备生物样品用于通过脱色样品进行视觉分析,用荧光染料非特异性地染色样品,并在澄清溶液中平衡沉淀的非特异性染色的样品,其中清除溶液的折射率近似于样品的折射率。 样本的视觉分析可以包括例如确定生物样本中异物的分布,数量和大小。 此外,可以评估围绕异物的组织的形态。
