- Description
- 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. PE-eFluor® 610 can be excited with laser lines from 488-561 nm and emits at 607 nm. We recommend using a 610/20 band pass filter (equivalent to PE-Texas Red®). Please make sure that your instrument is capable of detecting this fluorochome. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically. Excitation: 488-561 nm; Emission: 607 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

- Staining of 3-day cultured normal human peripheral blood cells with Anti-Human CD14 FITC (Product # 11-0149-42) and Mouse IgG1 K Isotype Control PE-eFluor® 610 (Product # 61-4714-82) (left) or Anti-Human CD169 (Siglec-1) PE-eFluor® 610 (right). Viable cells in the monocyte gate, as determined by Fixable Viability Dye eFluor® 780 (Product # 65-0865-14), were used for analysis.
