Description
Leptin is a protein product of the mouse obese gene . It modulates multiple functions including energy homeostasis, thermoregulation, bone metabolism, endocrine, and pro-inflammatory immune responses. As a signal molecule with growth factor characteristics, leptin can stimulate osteoblastic cells and inhibit osteoclast formation and activity, thus promoting osteogenesis.

Reconstitution |
1.We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile PBS, pH 7.4, with 0.1% BSA to a concentration of 0.1-1.0 mg/mL. 2.Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. 3.Further dilutions should be made in PBS, which must contain carrier proteins, such as 0.1% BSA, 10% FBS, 5% HSA, 5% trehalose, one of four options. 5% trehalose is recommended for experimental culture without serum. |
