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 60.3 kDa. The protein migrates as 80-100 kDa under reducing (R) condition, and 130-150 kDa and 250-300 kDa under non-reducing (NR) 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, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景（Background）
Sialic acid-binding Ig-like lectin 6 (SIGLEC6) is also known as CD antigen CD327, CD33 antigen-like 1 (CD33L or CD33L1), Obesity-binding protein 1 (OB-BP1). SIGLEC6 belongs to the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family, which contains two Ig-like C2-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. SIGLEC6 mediates sialic-acid dependent binding to cells. SIGLEC6 binds to alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.
