Storage and Stability: This product is stable for up to 6 months at temperatures below -70°C after receipt. After reconstitution, the product should be stable for 1 week at 4°C or 3 months at -20°C. For long-term storage, the addition of a carrier protein (e.g. 0.1% BSA) is recommended. Avoid repeated freeze-thaw cycles

Bioactivity: Interleukin-10 (IL-10), originally known as cytokine synthesis inhibitory factor (CSIF), belongs to the IL-10 family and shares more than 80% sequence homology with the Epstein-Barr virus protein BCRFI. It is produced by many immune cells, such as T cells, macrophages, mast cells and dendritic cells. It is usually secreted as a homodimer and, upon binding to receptors, inhibits the synthesis of several cytokines, including IFN-gamma, IL-2, IL-3, TNF, and GM-CSF produced by activated macrophages and Th2 cells. it also shows the ability to inhibit the function of antigen-presenting cells (APCs). The net effect of interleukin-10 appears to be inhibitory; however, stimulatory effects, such as stimulation of B-cell maturation and antibody production, have also been reported.

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.
