Ready-to-use ELISA kits are available for the detection of CD328, an alias of the protein, sialic acid binding Ig like lectin 7. The official gene symbol is SIGLEC7. The protein, with a mass of 51.1 kDa and length of 467 residues, is reported to be membrane-associated. It is a member of the Immunoglobulin superfamily, SIGLEC (sialic acid binding Ig-like lectin) family and may be known by other names, including: CDw328, CD328, sialic acid binding immunoglobulin-like lectin 7, adhesion inhibitory receptor molecule 1 siglec-7, QA79 membrane protein, and AIRM-1, and QA79.
