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 for 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: TNF is secreted by macrophages, monocytes, neutrophils, T cells, and NK cells upon stimulation by bacterial LPS. Cells expressing CD4 secrete TNF-α, while CD8 cells secrete little or no TNF-α. TNF-α synthesis is induced by many different stimuli, including interferon, IL2, and GM-CSF. TNF-β is a potent mediator of inflammatory and immune responses. It belongs to the TNF family of ligands and signals through TNFR1 and TNFR2. TNF-β is produced by activated T and B lymphocytes and has similar activity to TNF-α. It mediates a large number of inflammatory, immunostimulatory and antiviral responses.

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.
