Human Siglec-6, Fc Tag (SI6-H5256) is expressed from human 293 cells (HEK293). It contains AA Gln 16 - Val 320 (Accession # AAH35359).
Predicted N-terminus: Gln 16
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 60.3 kDa. As a result of glycosylation, 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).
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

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.
