Biotinylated Human Siglec-8 Protein

Product Info
Source

Recombinant Biotinylated Human Siglec-8 Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Met17-Ala363.[Accession | Q9NYZ4]

Molecular Weight

The protein has a predicted MW of 40.7 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis PAGE result.

Endotoxin

Less than 1EU per μg by the LAL method.

Purity

> 95% as determined by Tris-Bis PAGE

Formulation

Supplied as 0.22μm filtered solution in PBS (pH 7.4).

Storage

The product should be stored at -70℃. Please do not repeated freeze-thaw cycles.

Assay Data
Tris-Bis PAGE

Biotinylated Human Siglec-8 on Tris-Bis PAGE under reduced conditions. The purity is greater than 95%.

Background

Siglec-8, also known as SAF, is an approximately 75 kDa transmembrane glycoprotein in the Siglec family of sialic acid-binding immune regulatory molecules. Mature human Siglec-8 consists of a 347 amino acid (aa) extracellular domain (ECD) with three Ig-like domains.Putative adhesion molecule that mediates sialic-acid dependent binding to red blood cells. Preferentially binds to alpha-2,3-linked sialic acid. Also binds to alpha-2,6-linked sialic acid.

Synonyms

Biotinylated Recombinant human siglec 8 Protein on Tris-Bis PAGE under reduced conditions. The purity is greater than 95%.
