表达区间及表达系统(Source)

Human Siglec-3 (R119G), Fc Tag (CD3-H5254) is expressed from human 293 cells (HEK293). It contains AA Asp 18 - His 259


蛋白结构(Molecular Characterization)

Online(Asp 18 - His 259) AAH28152.1 (R119G)

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 53.1 kDa. The protein migrates as 64-70 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.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
