Name : Human Siglec-10 Protein
Product Source :
Recombinant Human Siglec-10 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Met17-Thr546.[Accession | Q96LC7-1]
Molecular Weight :
The protein has a predicted MW of 59.2 kDa. Due to glycosylation, the protein migrates to 70-79 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in 20mM PB, 150mM NaCl, 25mM L-arginine (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human Siglec-10 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human Siglec-10 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human Siglec-10, His Tag at 0.5μg/ml (100μl/Well). Dose response curve for Anti-Siglec-10 Antibody, hFc Tag with the EC50 of 5.6ng/ml determined by ELISA (QC Test). SPR Data Human Siglec-10, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human CD52, mFc Tag with an affinity constant of 15.9μM as determined in SPR assay (Biacore T200).
Background :
Siglec-10 is a ligand for CD52, the target of the therapeutic monoclonal antibody Alemtuzumab. It is also reported to bind to Vascular adhesion protein 1 (VAP-1) and to the co-stimulatory molecule CD24 also known as HSA (Heat-stable antigen).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.
Synonyms :
SLG2; SIGLEC10; MGC126774; PRO940
