rh ADAM8 fused with a polyhistidine tag at the C-terminus, has a calculated MW of 71.6 kDa, which migrates as a 120-150 kDa band in DTT-reduced SDS-PAGE due to glycosylation. Two main fragments bands are visible with apparent MW of 67 kDa and 46 kDa respectively in reduced SDS-PAGE as a result of its being prone to proteolytic cleavage.
>85% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, 20 mM CaCl2, pH7.5. Normally trehalose is added as protectant before lyophilization.
