Description

The eBio129c monoclonal antibody reacts with mouse PDCA-1 (BST2, CD317), a specific marker of plasmacytoid dendritic cells (pDC), also known as type I IFN-producing cells (IPC) in the naïve mouse. Mouse IPCs are typically CD11c+, CD11b-, B220+, Ly-6C+, and CD62L+. PDCA-1 is predominantly expressed by IPCs in the naïve mouse which represent sa very minor population (<0.5%) of splenocytes. It is upregulated on numerous cell types following stimulation which triggers an IFN response. PDCA-1 cycles between cell surface and intracellular compartments and may function to regulate trafficking of secreted cytokines. PDCA-1 (BST2) is the protein recognized by the antibody 120G8.

The epitope recognized by eBio129c is distinct from eBio927; thus, the antibodies can be used to costain, purify and identify pDCs.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This eBio129c (129c) antibody has been reported for use in flow cytometric analysis.

Applications Tested

This eBio129c (129c) antibody has been tested by flow cytometric analysis of BST2 transfected cells. This can be used at less than or equal to 0.25 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
