背景资料

Lymphotoxin alpha, a member of the tumor necrosis factor family, is a cytokine produced by lymphocytes. LTA is highly inducible, secreted, and exists as homotrimeric molecule. LTA forms heterotrimers with lymphotoxin-beta which anchors lymphotoxin-alpha to the cell surface. LTA mediates a large variety of inflammatory, immunostimulatory, and antiviral responses. LTA is also involved in the formation of secondary lymphoid organs during development and plays a role in apoptosis.

溶解建议

提供的人肿瘤坏死因子β(TNF b)产品为过滤灭菌的白色冻干粉末；该冻干粉末是从含人肿瘤坏死因子β(TNF b)的溶液（不含添加剂）中冻干产生的。我们建议加无菌的18MΩ-cm水以配制工作储存液到不低于100μg/ml，后继实验过程中可根据实验要求进一步稀释。

保存建议

人肿瘤坏死因子β(TNF b)在室温可保存3周，或置于-18℃冻存用于长期保存。重新溶解后可以在4℃冷藏保存至少2-7天；如果想延长保存时间，建议分装（加载体蛋白如0.1% HSA或 BSA）后置于-18℃冻存。请避免反复冻融。
