蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 53.8 kDa. Two main fragments bands are visible with apparent MW of 57-65 kDa and 35-40 kDa respectively in reduced SDS-PAGE as a result of its being prone to proteolytic cleavage.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳（SDS-PAGE）
Human ADAM8, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.
背景（Background）
Disintegrin and metalloproteinase domain-containing protein 8 is also known as ADAM8, Cell surface antigen MS2 and CD antigen CD156a, which belongs to the ADAM (a disintegrin and metalloprotease domain) family. ADAM family play a fundamental role in diverse processes such as asthma, development, angiogenesis and cancer through their activities in cell adhesion/fusion, membrane protein shedding, and signal transduction. ADAM8 / CD156a contains 1 disintegrin domain, 1 EGF-like domain and 1 peptidase M12B domain. ADAM8 / MS2 / CD156a is expressed on neutrophils and monocytes. ADAM8 / MS2 possible involvement in extravasation of leukocytes.
