Siglec-8 Protein, Human (HEK293, His-Avi)

Siglec-8 protein is a putative adhesion molecule that mediates sialic acid-dependent binding to erythrocytes, preferring α-2,3-linked sialic acid and interacting with α-2,6-linked sialic acid . Its sialic acid recognition site may be hidden through cis interactions with sialic acid on the surface of the same cell. Siglec-8 Protein, Human (HEK293, His-Avi) is the recombinant human-derived Siglec-8 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Siglec-8 protein, identified as a putative adhesion molecule, serves as a mediator for sialic-acid dependent binding to red blood cells. It exhibits a preference for binding to alpha-2,3-linked sialic acid and also interacts with alpha-2,6-linked sialic acid. Notably, the sialic acid recognition site of Siglec-8 may be concealed due to cis interactions with sialic acids present on the same cell surface. Furthermore, it has the ability to simultaneously recognize epitopes featuring a terminal N-acetylneuraminic acid (sialic acid) and an underlying 6-O-sulfated galactose, with a specific affinity for Gal-6-sulfated sialyl-Lewis X glycan epitopes.
