Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.
Other clonesOverlap in epitope recognition with REA818
44E9R (rIgG2a)-
Cells were incubated with an excess of purified unconjugated CD317 (PDCA-1) (REA818) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Specifications for CD317 (PDCA-1) Antibody, anti-mouse, REAfinity™


Clone REA818 recognizes the mouse CD317 antigen, also known as mouse plasmacytoid dendritic cell antigen-1 (PDCA-1) or BST2. CD317 is specifically expressed on mouse PDCs, a subset of CD11c
dendritic cells detected at low frequency in all lymphoid tissues, peripheral blood, and some non-lymphoid tissues. In mouse spleen, bone marrow, and lymph nodes, CD317 is exclusively expressed on cells which are CD11c
, Ly-6C
, CD45R (B220)
, MHC class II
, CD8a
, CD80
, CD86
, CD40
, CD11b
, CD90
, CD49b (DX5)
, CD3
, CD19
, i.e., on cells with the phenotype of mouse PDCs. Multi-color fluorescent staining of spleen cells clearly revealed that all CD11c
CD45R (B220)
PDCs are PDCA-1
and that PDCA-1 expression is restricted to PDCs.
Additional information: Clone REA818 displays negligible binding to Fc receptors.
