Hadamard变换显微图象分析 Ⅲ.单细胞内DNA,RNA和蛋白质的分析

Hadamard Transform Microscope Image Analysis III. Analysis of DNA, RNA and Protein in a Single Cell

本文用自制的Hadamard变换显微图象分析仪分析了AO和FITC染色的单细胞的荧光光谱,用该仪器获取了单个洋葱细胞核内DNA的分布图象,并在535nm处分别测定了AO染色的鸡红血细胞及洋葱表皮细胞核的荧光强度.所得结果与生物学结果吻合,显示了该仪器在单细胞试样分析中的应用价值.

The spectra of single AO and FITC stained cell or nucleus were analyzed by the domestic made instrument of Hadamard transform microscope image analysis. The DNA distribution image in single nucleus of allium cepa epidermal cell was obtained. The instrument was also applied to determine the fluorescence intensity of single cell or nucleus. The results show that the instrument can be used to analyze fluorescence spectra, fluorescence image and distributions and fluorescence intensity of a single cell. The results also show that the instrument is potentially applicable in cytobiology.
