Siglecs (sialic acid binding Ig-like lectins) belong to the immunoglobulin superfamily. Siglec-G is the apparent ortholog of human Siglec-10. It is expressed by mature B cells, but significant levels of transcript were also detected in DC, myeloid cells, and to a lesser extent, T cells. Mature Siglec-G consists of a 526 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 124 aa cytoplasmic domain. Siglec-G is a member of the CD33-related Siglec family in the mouse, and is involved in negative regulation of B-cell antigen receptor signaling and specifically acts on B1 cells to inhibit Ca2+ signaling, cellular expansion and antibody secretion.
Lyophilized from a 0.22 µm filtered solution of PBS, pH 7.4. Contact us for customized product form or formulation.
Application Notes:
Cross-Reactivity: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage,it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA,5% HSA,10% FBS or 5% Trehalose),and aliquot the reconstituted protein solution to minimize free-thaw cycles.
