Name : Biotinylated Human Siglec-10 (R119A) Protein
Product Source :
Recombinant Biotinylated Human Siglec-10(R119A) Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Met17-Thr546.[Accession | Q96LC7-1]
Molecular Weight :
The protein has a predicted MW of 62.64 kDa. Due to glycosylation, the protein migrates to 68-80 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per ug 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 Tirs 150mM NaCl, 200mM L-arginine (pH 8.0). 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.

Dose response curve for Anti-Siglec-10 Antibody, hFc Tag with the EC50 of 9.1ng/ml determined by ELISA.
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
