Biological Activity

Lipopolysaccharides (LPS) is an endotoxin derived from the outer leaflet of the outer membrane of Gram-negative bacteria. Lipopolysaccharide is a highly immunogenic antigen which can enhance immune responses. This product is derived from Escherichia coli O55:B5. Its potency is more than 500,000 EU/mg.

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.
