This work reports on the application of Raman spectroscopy for the analysis of Xenopus laevis oocytes (stage-I). A two-color home-made microscope has been used for this investigation. In particular, a 785nm Raman probe has been used to acquire the spontaneous Raman scattering from the oocyte cytoplasm, while a 532nm probe has been employed to detect carotenoids through Resonant Raman Scattering. Finally, the distribution of beta-carotene along a diameter of a single oocyte has been investigated.
本工作报道了拉曼光谱在分析非洲爪蟾卵母细胞(I 期)中的应用。为此研究使用了一台自制的双色显微镜。具体来说,使用 785nm 的拉曼探头获取卵母细胞质体的自发拉曼散射,而使用 532nm 的探头通过共振拉曼散射来检测类胡萝卜素。最后,研究了单个卵母细胞直径上β-胡萝卜素的分布。
