| Product Description | Recombinant Human Siglec-5/CD170 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Glu17-Thr434. |
Product Background |
Interactions between endothelial selectins and the leukocyte counter-receptor PSGL1 mediates leukocyte recruitment to inflammation sites. PSGL1 is highly sialylated, making it a potential ligand for Siglec-5, a leukocyte-receptor that recognizes sialic acid structures. Binding assays using soluble Siglec-5 variants (sSiglec-5/C4BP and sSiglec-5/Fc) revealed a dose- and calcium-dependent binding to PSGL1. |
