Product Specific Information

Description: This 7-239 monoclonal antibody reacts with human CD169, also known as Siglec-1 and Sialoadhesin. This type I transmembrane protein is a member of the sialic acid binding Ig-like lectin (Siglec) family. Expressed on macrophages and dendritic cells in peripheral blood, lymph nodes, and spleen in humans, CD169 binds glycoproteins and glycolipids containing N-acetylneuraminyl alpha 2-3-galactose. CD169 expression can also be induced on CD14+ monocytes by interferon-alpha and interferon-gamma to mediate HIV-1 infection. Finally, CD169 has also been shown to be involved in antigen presentation to invariant NK T cells.

This monoclonal antibody has been reported to inhibit erythrocyte binding to CD169-expressing cells.

Applications Reported: This 7-239 antibody has been reported for use in flow cytometric analysis.

Applications Tested: This 7-239 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.5 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

The siglecs are a family of membrane bound lectins (of the immunoglobulin superfamily) that bind sialic acid and mediate cell-cell interactions. Family members include sialoadhesin, CD22 and CD33. Sialoadhesin is a macrophage-specific cell adhesion molecule that is expressed on activated macrophages in chronic inflammation and in tumours.
