Applications for Human Siglec-10 Antibody

Application
Recommended Usage

Blockade of Receptor-ligand Interaction

In a functional ELISA, 1-4 µg/mL of this antibody will block 50% of the binding of 1.5 μg/mL of biotinylated 6’‑Sialyllactose-Polyacrylamide to immobilized Recombinant Human Siglec-10 Fc Chimera (Catalog # 2130-SL) coated at 5 µg/mL (100 µL/well). At 30 μg/mL, this antibody will block >90% of the binding.

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Background: Siglec-10

Siglecs (sialic acid binding Ig-like lectins) are I-type lectins that belong to the immunoglobulin superfamily. They are characterized by an N‑terminal Ig-like V-type domain which mediates sialic acid binding, followed by a varying number of Ig-like C2-type domains. Siglecs 5‑11 constitute the CD33/Siglec-3 related group, and are differentially expressed in the hematopoietic system (1‑3). Siglec-G is the apparent ortholog of human Siglec-10 (4). The human Siglec-10 cDNA encodes a 697 amino acid (aa) precursor that includes a 16 aa signal sequence, a 534 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 126 aa cytoplasmic domain. The ECD contains one Ig-like V‑type domain and four Ig-like C2-type domains, while the cytoplasmic domain contains two immunoreceptor tyrosine-based inhibitory motifs (ITIM) (5‑8). Five splice variants of human Siglec-10 differ in their deletions within the ECD. A potentially secreted sixth variant contains the Ig-like V-type domain followed by a 45 aa substitution (5‑7, 9). Within the ECD, human Siglec-10 is most closely related to Siglec-5 (42% aa sequence identity). It shares 63% aa sequence identity with mouse Siglec-G. Siglec-10 is expressed on eosinophils, neutrophils, monocytes, and B cells (5, 8) with some splice variants predominating in particular cell types and tissue locations (6, 7, 9). It is up‑regulated on eosinophils in mouse models of allergic respiratory inflammation (10). Siglec-10 binds sialated proteins and lipids in alpha 2,3 or alpha 2,6 linkage and shows a preference for GT1b gangliosides (7, 11). This binding can be modulated by cis interactions of Siglec-10 with sialated molecules expressed on the same cell (7). When tyrosine phosphorylated, the cytoplasmic ITIMs interact with phosphatases SHP-1 and SHP-2 to propagate inhibitory signals (5, 9).
