Ferroheme 

Ferroheme is a complex of ferrous ions and porphyrins, which exists in tissues in free form and as a prosthetic group of many heme proteins. In addition, ferroheme is also an isosteric inhibitor of fatty acid binding to rat liver fatty acid binding protein^[1][2][3].

*In solvent : -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen)

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
