蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 52.1 kDa. The protein migrates as 58-66 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）
>85% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

背景（Background）
C-type lectin superfamily 4, member G (CLEC4G) is also known as liver and lymph node sinusoidal endothelial cell C-type lectin (LSECtin), which is a member of subgroup II of the C-type (Ca2+-dependent) lectin superfamily. CLEC4G / LSECtin binds to mannose, GlcNAc, and fucose in a Ca2+-dependent manner. In addition, CLEC4G / LSECtin has the ability to bind to surface glycoproteins of enveloped viruses. In particular, interaction of LSECtin with the surface glycoproteins of severe acute respiratory syndrome (SARS) coronavirus and Ebola virus has been described, and LSECtin-mediated infection of cells by Ebola virus has been demonstrated.
