Siglec-5 Protein, Mouse (HEK293, His)

Customer Review

Based on 1 Customer Validation

Siglec-F Protein, a putative adhesion molecule, crucially mediates sialic-acid dependent binding to cells with a preferential affinity for alpha-2,3-linked sialic acid. Notably, its sialic acid recognition site may be concealed through cis interactions with sialic acids on the same cell surface. Siglec-5 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Siglec-5 protein, expressed by HEK293 , with C-His labeled tag.

Description

Siglec-F Protein, a putative adhesion molecule, crucially mediates sialic-acid dependent binding to cells with a preferential affinity for alpha-2,3-linked sialic acid. Notably, its sialic acid recognition site may be concealed through cis interactions with sialic acids on the same cell surface. Siglec-5 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Siglec-5 protein, expressed by HEK293 , with C-His labeled tag.

Background

Siglec-F protein, characterized as a putative adhesion molecule, plays a crucial role in mediating sialic-acid dependent binding to cells. It exhibits a preferential affinity for alpha-2,3-linked sialic acid. It is noteworthy that the sialic acid recognition site of Siglec-F may be concealed due to cis interactions with sialic acids present on the same cell surface.
