描述（Description）
IL-1 alpha is a ubiquitous and pivotal pro-inflammatory cytokine. IL-1 alpha is produced by monocytes and macrophages as a proprotein, which is proteolytically processed and released in response to cell injury, and thus induces apoptosis. IL-1 alpha plays an important role in inflammation and bridges the innate and adaptive immune systems. IL-1 alpha mediates the activation of NF-kappa-B and the three MAPK pathways p38, p42/p44 and JNK pathways[1][4]. IL-1 alpha protein, Human is a recombinant protein consisting of 159 amino acids (S113-A271) and is produced by E. coli.

制劑（Trait）
Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 150mM NaCl, pH 7.5.
復(fù)溶（Reconstitution）
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
保存條件&效期（Storage & Stability）
Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
運(yùn)輸方式(Shipping)
Room temperature in continental US; may vary elsewhere.
