Sodium butyrate is the sodium salt of butyric acid, used in the culture of mammalian cells. Sodium butyrate inhibits most HDAC except class III HDAC and class II HDAC6 and -10. Sodium butyrate also is the most effective fatty acid in stimulating or repressing the expression of specific genes. Sodium butyrate induces p21 mRNA expression in an immediate-early fashion, through transactivation of a promoter cis-element(s) located within 1.4 kb of the transcriptional start site, independent of p53 binding. Sodium butyrate significantly extends survival in a dose-dependent manner, improves body weight and motor performance, and delays the neuropathological sequelae in the R6/2 transgenic mouse model of Huntington's disease (HD). Sodium butyrate also increases histone and specificity protein-1 acetylation and protects against 3-nitropropionic acid neurotoxicity. Can be used to construct animal models of venous stenosis.

| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

| Heparin sodium salt (MW 15kDa)
Heparin sodium salt (MW 15kDa) is a heparin polymer with a molecular weight of 15kDa.Heparin sodium salt is an anticoagulant that reversibly binds to antithrombin III (ATIII), thereby accelerating the rate of inactivation of Thrombin factor IIa and factor Xa by ATIII. Heparin sodium salt is used for blood collection and plasma preparation in experimental animals and for the construction of parenteral nutrition models in mice. |
