Description

Description

This SAFE (Serum and Animal Free, low Endotoxin) protein has been made in plants with no exposure to animal protein during expression or purification. This animal free product has very low levels of endotoxin.

Human TNF alpha is a memeber of the TNF ligand superfamily produced by macrophages, monocytes, neutrophils, CD4+ T cells and NK cells. A 24 kDa form of TNF alpha is expressed as a membrane bound molecule. TNF alpha is cytolytic and plays an important role in immune regulation. Dimers and trimers of TNF alpha have been observed. Human and mouse TNF alpha conservation is about 79%, Human protein is functional on mouse, although with slightly reduced activity.

The lyophilized powder can be stored at less than or equal to -20°C. (Short term storage at 2-8°C). Reconstitute in sterile PBS to a concentration no less than 100μg/mL. Once reconstituted, protein should be aliquoted and stored at -20°C or lower. For best stability add 0.1% BSA before freezing aliquots
