Zebrafish High Throughput Screening
Zebrafish High Throughput Screening is a rapidly emerging technology in the fields of biomedical research and drug development. As a vertebrate model, zebrafish combines the high-throughput capabilities of in vitro experiments with the systemic physiological advantages of mammalian models, making it an ideal bridge between basic research and clinical applications. The core of zebrafish high throughput screening lies in utilizing its biological characteristics—embryonic transparency, rapid development (early organ formation within 24 hours), and high reproductive capacity (200-300 eggs per week)—combined with automated imaging and analysis systems, enabling rapid phenotypic evaluation of large sample sizes.
This technology has found widespread application in drug activity screening, toxicity evaluation, gene function research, and disease mechanism exploration. In drug development, zebrafish high throughput screening demonstrates unique value. Its core advantage lies in simultaneously assessing both the therapeutic effects and toxicological characteristics of compounds. By observing real-time physiological indicators such as heartbeats, blood circulation, and neuronal activity, researchers can complete multi-parametric pharmacodynamic evaluations of thousands of compounds within 72 hours. For example, in anti-cancer drug screening, using transgenic zebrafish tumor models, researchers can directly observe the effects of drugs on angiogenesis and tumor metastasis. This three-dimensional dynamic assessment is not achievable with traditional cell models. Zebrafish high throughput screening has also shown strong performance in environmental toxicology. Its sensitive environmental response mechanisms can detect pollutants at the ppb (parts per billion) level. The European Union's REACH regulations have included zebrafish as a standard model for chemical risk assessment. By establishing fluorescent reporter gene lines, researchers can visually monitor the toxic effects of heavy metals, endocrine disruptors, and other pollutants on specific organs. This allows for parallel handling of 500-1000 water quality samples in a single experiment, significantly improving environmental monitoring efficiency. Furthermore, the technology has achieved breakthroughs in genetic disease research. Human disease zebrafish models constructed using CRISPR technology have been successfully applied in screening therapeutic options for rare diseases such as cystic fibrosis and Duchenne muscular dystrophy.
Key Technologies and Implementation Points of Zebrafish High Throughput Screening
1. Standardized Cultivation System Construction
(1) Use of automated multi-well plate cultivation systems (usually 96 or 384-well plates).
(2) Strict control of water temperature (28.5±0.5°C), conductivity (500-1500μS/cm), and light cycle (14h light/10h dark).
(3) Embryo synchronization treatment must be completed within one hour post-fertilization.
2. Automated Phenotypic Analysis Platform
(1) High-content imaging systems (such as PerkinElmer Operetta) achieve subcellular resolution.
(2) Movement trajectory analysis for screening neuroactive substances (sampling frequency ≥30fps).
(3) Machine learning algorithms for automatic classification of phenotypes such as pericardial edema and spinal curvature.
3. Key Quality Control Points
(1) Fertilization rate must remain stable above 90% (indicating population health status).
(2) Experimental and control groups must be treated in the same batch (to avoid developmental timing discrepancies).
(3) DMSO solvent concentration strictly controlled below 1% (to prevent non-specific effects).
4. Common Technical Challenges and Responses
(1) Pigmentation interference: Use of casper mutants or PTU treatment.
(2) Individual variability: At least 30 embryos per treatment group (statistical power >80%).
(3) False positive exclusion: Establishment of a double-blind evaluation system.
Advantages of Zebrafish High Throughput Screening
1. Rapid Development and Low Cost, Suitable for Large-Scale Research
(1) Zebrafish embryos can complete major organ development within 48-72 hours.
(2) Cultivation in 96-well/384-well plates compatible with automated liquid handling workstations and imaging systems.
2. Phenotype Visualization and Easy Automation
(1) Embryos and larvae are transparent, allowing direct observation of heartbeats, blood flow, and developmental defects.
(2) Fluorescent labeling can be combined for real-time in vivo imaging and behavioral analysis.
3. High Gene Homology with Humans, Suitable for Disease Modeling
(1) Approximately 70% of human genes have homologs in zebrafish.
(2) Models for cardiovascular diseases, tumors, inflammation, and neurodegenerative diseases can be constructed.

Technological Integration Trend: Zebrafish High Throughput Screening × Multi-Omics Analysis
Traditional zebrafish screening relies on manual observation, limiting data dimensionality. Current research emphasizes “closing the loop from phenotype to molecular mechanism,” which requires deep integration of zebrafish platforms with omics technologies such as proteomics, metabolomics, and transcriptomics.

(1) Comparing signal pathway activation, protein phosphorylation, and post-translational modification changes in zebrafish tissues from different treatment groups.
(2) Supports TMT, Label-free, and PRM quantitative strategies.
2. Zebrafish + Metabolomics
(1) Rapidly capturing metabolic disturbances and recovery processes, revealing drug mechanisms of action or toxic side effects.
(2) Can cover various physiological fluids (blood, brain tissue, intestine, etc.).
