Basic Description

Product Name	Recombinant Human Siglec-9 Protein, ≥95% (SDS-PAGE), high purity
Synonyms	Sialic Acid Binding Ig-like Lectin 9 \| CD329 \| CDw329 \| FOAP-9 \| OBBP-Like \| Protein FOAP-9 \| sialic acid-binding Ig-like lectin 9 \| Siglec9 \| Siglec-9
Grade	ActiBioPure™, Animal Free, Azide Free, Bioactive, Carrier Free, High Performance
Product Description	Purity ≥95% SDS-PAGE. Endotoxin level <0.1 EU/µg Function Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,3- or 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.
