Name :
Human Siglec-15 / CD33L3 Protein, His Tag (MALS verified)

Background :
Siglec-15 is a DAP12-associated immunoreceptor, which belongs to the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family. Siglecs are cell surface proteins that bind sialic acid. They are found primarily on the surface of immune cells and are a subset of the I-type lectins. Siglec-15 consisting of immunoglobulin (Ig)-like domains, transmembrane domain and a short cytoplasmic tail. Siglec-15 is that recognizes sialylated glycans and regulates osteoclast differentiation. Siglec-15 is a potential therapeutic target for osteoporosis and plays a conserved regulatory role in the immune system of vertebrates.

Biological Activity :
Immobilized Human Siglec-15, His Tag (Cat. No. SG5-H52H3) at 1 μg/mL (100 μL/well) can bind Mouse Human chimeric mAb (5G12, Human IgG1) with a linear range of 0.2-2 ng/mL (QC tested).
