Name : Human Siglec-5/CD170 Protein

Product Source :
Recombinant Human Siglec-5/CD170 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Glu17-Thr434.[Accession | O15389]

Molecular Weight :
The protein has a predicted MW of 49.3 kDa. Due to glycosylation, the protein migrates to 68-78 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 :
Supplied as 0.22μm filtered solution in PBS, 360mM NaCl (pH 7.4).

Reconstitution :

Storage and Stability :
Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Human Siglec-5 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human Siglec-5 is greater than 95% as determined by SEC-HPLC.

Background :
Siglecs (sialic acid binding Ig-like lectins) are I-type (Ig-type) lectins belonging to the Ig superfamily. They are characterized by an N-terminal Ig-like V-type domain which mediates sialic acid binding, followed by varying numbers of Ig-like C2-type domains. Siglec 5 is putative adhesion molecule that mediates sialic-acid dependent binding to cells. Binds equally to alpha-2,3-linked and alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.

Synonyms :
CD170; CD33 antigen-like 2; CD33L2; OBBP2; Siglec5; SIGLEC5; OB-BP2
