• Protein Length: Gln20-Phe355
• Description: Siglecs are sialic acid specific I-type lectins that are characterized by an extracellular domain (ECD) with an N-terminal Ig-like V-set domain followed by varying numbers of Ig-like C2-set domains. Mouse Siglec-E, also known as Myeloid Inhibitory Siglec (MIS), is an 80 - 85 kDa member of the CD33-related subfamily of Siglecs. Rodent and primate Siglec gene families have significantly diverged, and Siglec-9 is the most likely human ortholog of mouse Siglec-E. Siglec-E is expressed as a heavily N-glycosylated disulfide-linked homodimer and shows binding preference for disialic acids in the alpha 2-8 linkage. Siglec-E is up-regulated and additionally phosphorylated following cellular stimulation by a variety of TLR agonists. Siglec-E signaling negatively regulates the LPS-induced production of TNF- alpha and IL-6 by macrophages. Its up-regulation in macrophages parallels the development of endotoxin tolerance. Siglec-E recognition of sialylated determinants on virulent T. cruzi contributes to the suppression of dendritic cell IL-12 p40 production.
• Form: Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 150mM NaCl, pH 8.5.
• Molecular Mass: 85-95kDa, reducing conditions.
• Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
• Purity: Greater than 95% as determined by reducing SDS-PAGE.
• Storage: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
  Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
  Aliquots of reconstituted samples are stable at < -20°C for 3 months.
• Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
  It is not recommended to reconstitute to a concentration less than 100μg/ml
  Dissolve the lyophilized protein in distilled water.
  Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Shipping: The product is shipped at ambient temperature.
  Upon receipt, store it immediately at the temperature listed below.
