分子别名(Synonym)

SIGLEC5,OB-BP2,CD170,CD33L2

表达区间及表达系统(Source)

Human Siglec-5, Fc Tag (SI5-H5250) is expressed from human 293 cells (HEK293). It contains AA Glu 17 - Thr 434 (Accession # AAH29896).

Predicted N-terminus: Glu 17

蛋白结构(Molecular Characterization)

Online(Glu 17 - Thr 434) AAH29896

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

The protein has a calculated MW of 73.0 kDa. The protein migrates as 90-110 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 Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human Siglec-5, Fc Tag (Cat. No. SI5-H5250) SDS-PAGE gel

Human Siglec-5, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

背景(Background)

Sialic acid-binding Ig-like lectin 5 (SIGLEC5) is also known as CD33 antigen-like 2 (CD33L2), Obesity-binding protein 2 (OB-BP2), CD antigen CD170, which belongs to the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family. SIGLEC5 / CD170 is expressed by monocytic / myeloid lineage cells. SIGLEC-5 / CD33-L2 binds equally to alpha-2,3-linked and 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.
