C2,Complement C2,Complement Component C2
表达区间及表达系统（Source）
Cynomolgus Complement C2, His Tag (CO2-C52H8) is expressed from human 293 cells (HEK293). It contains AA Ala 21 - Leu 752 (Accession # G8F3W0-1).
Predicted N-terminus: Ala 21
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 83.0 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度（Purity）
>95% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.
