제품 설명
Dextran sulfate sodium salt (DSS) is a polyanionic derivative of dextran produced by the esterification of Dextran with chlorosulphonic acid. The sulfur content is approximately 17% which corresponds to an average of 1.9 sulfate groups per glucosyl residue of the dextran molecule. DSS has several characteristics: 1) polyanionic complex, soluble in water, forming a colorless aqueous solution; 2) high purity and good stability; 3) can be degraded naturally. Inflammatory bowel disease (IBD) is a chronic, relapsing gastrointestinal infection that increases the risk of intestinal tumors, mainly including UC and Crohn disease (CD). In 1985, after the hamster ulcerative colitis model was first prepared by using DSS, a large number of studies have proved that the DSS colitis model is similar to human ulcerative colitis. The histological features, clinical manifestations, disease site, and cytokine proliferation of the DSS colitis model are very similar to human ulcerative colitis (UC). The modeling conditions and operation methods of this model are simple, the expenditure is very cheap, the repeatability is good, and it is easy to master and popularize. The DSS concentration and dosing time can be adjusted according to the experimental purpose to establish acute, chronic, and acute-chronic alternation models.

Q1: What are the key factors that affect the success of DSS modeling?
A1: DSS concentration, molecular weight, administration time, animal species and rearing environment.
Q2: What is the daily volume of drinking water for rats and mice (including acute and chronic modeling)?
A2: 7-10 mL per day for mice (20~25 g) and 10~11 mL per day for rats (100 g).
Q3: Both DSS and TNBS are models of colitis. What is the difference between the two?
A3: DSS induces ulcerative colitis and TNBS induces Crohn's colitis.
Q4: What is the difference between GAPDH and actin for primer selection?
A4: The difference is not big. GAPDH is used more. It is recommended to use GAPDH as an internal reference for mice.
Q5: Mice have a high lethality rate
A5: Reason: DSS concentration is too high. Recommendation: Appropriately reduce the concentration of DSS administered
Q6: Mice have no symptoms of enteritis or low symptoms of enteritis
A6: Reason: DSS concentration is too low, suggestion: appropriately increase DSS administration concentration; or reduce cycle interval (10-14 days)
Q7: In the same group of mice, the symptoms of enteritis vary greatly
A7: Reasons: 1. The bottle cap was blocked; 2. Some mice did not drink/a small amount of DSS. Suggestions: 1. Check the mouse drinking bottle every day; 2. Each mouse is isolated and cultured separately, and the water intake of the mice is checked every day or the mice are pre-raised for 1-2 weeks after arrival, and the mice with abnormal water intake are excluded.
Q8: Which part of the colon is more reliable for HE staining?
A8: The mouse anus goes up 1-2 cm.
Q9: DSS treatment of NCM460, the recommended concentration for cell modeling
A9: It is recommended to incubate with 3% DSS for 24h.
