品系特点Strain characteristics
白化非洲爪蟾（Xenopus laevis albino，俗称"金蛙"）因黑色素合成基因突变导致色素完全缺失。蝌蚪及变态初期个体全身接近透明，心跳、血管与内部器官清晰可见，是活体动态成像的理想选择。成体体色粉红至浅金色，在共聚焦显微镜下色素背景噪声极低，荧光信号对比度显著优于野生型。Albino X. laevis ("golden frog") lack melanin due to a biosynthesis gene mutation. Tadpoles are near-transparent — heartbeat, vasculature and organs are visible in real time. Adults show pink-to-golden colouration with minimal autofluorescence, giving far better fluorescence contrast than wild-type under confocal imaging.
适用研究领域Research applications
- 发育生物学：胚胎发育过程的活体实时追踪，细胞谱系分析与细胞分化研究。Developmental biology: real-time live tracking of embryogenesis, cell lineage and differentiation.
- 荧光成像与示踪：色素背景噪声极低，显著提升荧光探针和 GFP 融合蛋白的信噪比，适合长时程活体成像。Fluorescence imaging & tracing: minimal autofluorescence greatly improves signal-to-noise for fluorescent probes and GFP fusions; ideal for long-term live imaging.
- 基因编辑与功能验证：CRISPR-Cas9 / Morpholino 实验后表型观察更为直观，内部结构变化一目了然。Gene editing & functional assays: phenotypic changes after CRISPR/Morpholino knockdown are clearly visible without dissection.
- 毒理学与安全性评价：药物毒理、环境毒理与致畸性测试的标准化生物模型。Toxicology & safety: standardised model for drug toxicity, environmental toxicology and teratogenicity screening.
- 教学示范：透明蝌蚪可直接在解剖镜下演示心跳、血液循环与器官发生，广泛用于高校生物学教学。Teaching: transparent tadpoles demonstrate heartbeat, circulation and organogenesis live under a dissecting scope — widely used in university biology courses.
