Description
Human Sialic acid-binding Ig-like lectin 9 (Siglec 9) is a Type I transmembrane protein and a member of the Siglec family and immunoglobulin superfamily. The recombinant Siglec 9 protein dimer (CSP-25206-01) is a cis-homodimer (cis-dimer) and contains a Siglec 9 extracellular domain (UniProt# Q9Y336, amino acids Gln18-Gly348) fused with a proprietary cis-dimer motif followed by a His tag at the C-terminus. This dimeric protein is expressed in HEK293T cells. The recombinant human Siglec 9 protein dimer can potently bind Siglec 9-specific antibodies. This Siglec 9 protein dimer can be used as an antigen for in vitro assays and antibody screening, and as an immunogen for immunization to generate antibodies targeting more conformational epitopes
