Biological Activity

L-Methionine is an essential amino acid for metabolism.

Chemical Information
Molecular Weight 149.21
Formula C5H11NO2S
CAS Number 63-68-3
Solubility (25°C) Water 10 mg/mL
Storage 2-8°C, protect from light, dry, sealed
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
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.
