    CD96 is a transmembrane glycoprotein that has three extracellular immunoglobulin-like domains and is expressed by all resting human and mouse NK cells. CD96 main ligand is CD155. CD 96 has approximately 20% homology with CD226 and competed for binding to CD155 with CD226. CD97: CD97 antigen encoded by the CD97 gene.

    The CD system is commonly used as cell markers in immunophenotyping, allowing cells to be defined based on what molecules are present on their surface. These markers are often used to associate cells with certain immune functions. While using one CD molecule to define populations is uncommon (though a few examples exist), combining markers has ...

    These isoforms are often used as markers that identify and distinguish between different types of immune cells. Naive T lymphocytes are typically positive for CD45RA, which includes only the A protein region. Activated and memory T lymphocytes express CD45RO, the shortest CD45 isoform, which lacks all three of the A, B, and C regions.

    Like many cell surface receptors/markers, CD4 is a member of the immunoglobulin superfamily. It has four immunoglobulin domains (D 1 to D 4) that are exposed on the extracellular surface of the cell: D 1 and D 3 resemble immunoglobulin variable (IgV) domains. D 2 and D 4 resemble immunoglobulin constant (IgC) domains.

    Another deliberate violation of the Red Book standard intended to make the CD play only on CD players and not on computers by applying bogus data track onto the disc during manufacturing, which CD players will ignore as non-audio tracks. The system could be disabled by tracing the outer edge of a CD with a felt-tip marker. [3] MediaMax CD3

    CD47 (Cluster of Differentiation 47) also known as integrin associated protein (IAP) is a transmembrane protein that in humans is encoded by the CD47 gene.CD47 belongs to the immunoglobulin superfamily [5] and partners with membrane integrins and also binds the ligands thrombospondin 1 (TSP-1) and signal-regulatory protein alpha (SIRPα).

  9. CD14 - Wikipedia

    en.wikipedia.org/wiki/CD14

    CD14 is expressed mainly by macrophages and (at 10-times lesser extent) by neutrophils.It is also expressed by dendritic cells.The soluble form of the receptor (sCD14) is secreted by the liver and monocytes and is sufficient in low concentrations to confer LPS-responsiveness to cells not expressing CD14. mCD14 and sCD14 are also present on enterocytes.
