The use of zebrafish Danio rerio as a model for intestinal damage is well established and the dextran sodium sulfate (DSS)-induced zebrafish IBD model mimics different features of mammalian IBD phenotypes, including neutrophilic inflammation in the intestine, excessive mucus production, increased intestinal lymphangiogenesis and upregulation of pro-inflammatory cytokines and markers ccl20, il1β, il23, il8, mmp9 and tnf-α^[1].

1. Model building

1.1 Animal Model

3dpf（days post fertilization) Zebrafish

1.2 Material

DSS(Yeasen#60316ES,MW36000-50000)、AB-PAS（Yeasen#60534ES）

1.3 Protocol

Zebrafish embryos were obtained from natural spawning and raised until 1 day post fertilization (dpf) in an incubator at 28.5℃ in recirculating water (60 μg/mL instant ocean sea salts) and supplemented with methylene blue up to 1 dpf； 
After 1 dpf, use E3 embryo culture medium without methylene blue to culture to 3 dpf；
Prepare 10% DSS storage solution with E3 medium；
Dilute DSS with culture medium to the maximum non lethal dose (DSS concentration reference: 0.5%);
The zebrafish were treated with 0.5% DSS from 3 dpf to 6 dpf, and the indexes were observed.

2. Results

The successful indicators of modeling: the number of neutrophils increased, acidic mucin increased, and the expression of inflammatory factors increased.
Number of neutrophils: the number of neutrophils increased and moved to the intestine and epithelium;
Acid mucus protein: It was verified by paraffin pathological section and AB-PAS staining method that the acid mucus protein in zebrafish intestine increased after DSS immersion;
 Inflammatory factor expression: The expression of an inflammatory factor in the zebrafish intestine increased after DSS treatment^[1,2].

4. Successful case for modeling with Yeasen DSS

Yeasen provides high-quality DSS (Cat#60316ES): purity (98%), sulfur content 17-19%, free sulfur <0.2%, supported by a large number of literature data.
