Target-Based Screening Services

Overview Target Classes Reporter Models Application

Overview

Target-based screening in zebrafish merges hypotheses of identified molecular targets or signaling pathways with whole-organism biology to evaluate compound activity in a physiologically relevant vertebrate system. Unlike using isolated cells or biochemical tests, zebrafish-based target screening allows researchers to analyze target modulation together with downstream biological responses, tissue-specific effects and early safety signals.

Our Target-Based Screening Services rely on transgenic reporter lines, mutant and gene-edited models, functional assays and quantitative imaging to study target and pathway modification in vivo. The platform supports target validation, pathway modulator discovery, mechanism-of-action (MoA) studies, and confirmation of cell-based screening results.

When to Use Target-Based Zebrafish Screening

Target-based zebrafish screening is well suited for projects requiring functional validation of molecular targets or signaling pathways in a living vertebrate model. Typical applications include:

In Vivo Target Validation – Confirm the biological relevance of a candidate target using zebrafish reporter, mutant, or gene-edited models.
Pathway Modulator Discovery – Screen compounds to identify activators or inhibitors of specific signaling pathways.
Mechanism Confirmation – Determine whether lead compounds regulate the intended target or pathway within an intact biological system.
Translation of Cell-Based Findings – Validate target engagement and functional responses observed in cell-based assays under physiological in vivo conditions.
Candidate Prioritization – Combine target modulation, efficacy, and early toxicity data to support informed candidate selection.

Reporter Models Platforms

Target-based screening relies on robust experimental models that directly or indirectly reflect target or pathway activity. We select the most appropriate platform according to the biological question and study objectives.

Transgenic Reporter Lines

Monitor tissue-specific gene expression, signaling pathway activity, or cellular responses through genetically encoded fluorescent reporters.

Mutant Zebrafish Models

Evaluate compound responses in genetic backgrounds carrying loss-of-function or disease-associated mutations to investigate target function and therapeutic relevance.

CRISPR Knockout or Knock-in Models

Support target validation, disease model development, and reporter model generation through precise genome editing.

Morpholino or Transient Knockdown Models

Provide rapid functional assessment of candidate genes during early-stage target validation or pathway investigation.

Overexpression or mRNA Injection Models

Generate gain-of-function models for pathway activation, target validation, and mechanistic studies.

Quantitative Target and Pathway Readouts

Target modulation is evaluated using quantitative, target-linked endpoints that provide objective evidence of pathway activity and downstream biological responses.

Our readouts may include:

Reporter fluorescence intensity
Reporter-positive cell number
Target gene expression
Pathway activation or inhibition index
Vascular density
Vessel branching
Immune cell recruitment
Cell migration
Apoptosis-related signals
Tissue-specific reporter responses
Downstream phenotype rescue
