Human Siglec-10 Protein, Fc (L117A, L118A) Tag

The siglecs (sialic acid-binding Ig-like lectins) are a distinct subset of the Ig superfamily with adhesion-molecule-like structure. We describe here a novel member of the siglec protein family that shares a similar structure including five Ig-like domains, a transmembrane domain, and a cytoplasmic tail containing two ITIM-signaling motifs. Siglec-10 was identified through database mining of an asthmatic eosinophil EST library. The Siglec-10-VAP-1 interaction seems to mediate lymphocyte adhesion to endothelium and has the potential to modify the inflammatory microenvironment via the enzymatic end products.

This protein carries a Fc (L117A, L118A) tag at the C-terminus. The protein has a calculated MW of 84.6 kDa. The protein migrates as 100-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. Mutations (L117A, L118A/EU number: L234A/L235A) in human immunoglobulin G1 (hIgG1) Fc diminish binding to FcγRI leading to a significant reduction in ADCC and CDC in comparison to wild type human IgG1.

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Human Siglec-10 Protein, Fc (L117A, L118A) Tag (Cat. No. SI0-H5254) at 5 μg/mL (100 μL/well) can bind Anti-Siglec-10 Antibody, Human IgG1 with a linear range of 0.1-6 ng/mL (QC tested).
