表达区间及表达系统（Source）
Human cluster Ⅳ Protein, Fc Tag (LR1-H5256) is expressed from human 293 cells (HEK293). It contains AA Ser 3332 - Asp 3779 (Accession # Q07954-1).
Predicted N-terminus: Ser 3332
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 76.6 kDa. The protein migrates as 95-130 kDa when calibrated against Star Ribbon Pre-stained Protein Marker 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）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
