表达区间及表达系统（Source）
Human MMP-9, His Tag (MM9-H5221) is expressed from human 293 cells (HEK293). It contains AA Ala 20 - Pro 469 (Accession # AAH06093). It needs to be activated by agents such as APMA in vitro to have hydrolytic activity.
Predicted N-terminus: Ala 20
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 50.8 kDa. The protein migrates as 58-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
偶联（Conjugate）
Unconjugated
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 with trehalose as protectant.
