Specificity

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.

Cells were incubated with an excess of purified unconjugated CD1c (BDCA-1) (REA694) 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.

Sensitivity

Performance comparison
Selected fluorochrome conjugated antibodies from Miltenyi Biotec were compared to commercially available hybridoma clones in flow cytometry analysis.

Flow cytometric comparison of different clones for CD1c (BDCA-1). Human peripheral blood mononuclear cells (PBMCs) were stained with CD1c (BDCA-1) antibodies and with a suitable counterstaining. As a control, CD1c (BDCA-1) antibody staining was omitted and cells were measured in the same channels. Flow cytometry was performed with the MACSQuant® Analyzer. Cell debris, dead cells, and cell doublets were excluded from the analysis based on scatter signals and 4',6-diamidino-2-phenylindole (DAPI) fluorescence. No FcR Blocking Reagent was used. The recommended titers of respective antibodies from different suppliers were used.

Overview

Clone REA694 recognizes the human CD1c antigen, also known as BDCA-1. CD1c is expressed on a major subpopulation of human myeloid dendritic cells (about 0.3% of blood leukocytes). Blood CD1c (BDCA-1)
+
myeloid dendritic cells are CD11c
high
, CD123
low
, CD4
+
, Lin
, CD45RO

, CD2
+
, CD16
, CD141 (BDCA-3)
low
, CD303 (BDCA-2)
, and CD304 (BDCA-4/Neuropilin-1)
. They express myeloid markers (CD13, CD33) as well as Fc receptors (CD32, CD64, FcεRI) and are of monocytoid appearance. A minor proportion of CD1c (BDCA-1)
+
myeloid dendritic cells expresses CD14 and CD11b. In blood, CD1c (BDCA-1) is also expressed on a subpopulation of CD19
+
small resting B lymphocytes. CD1c (BDCA-1) expression has also been detected on cortical thymocytes, on Langerhans cells, and on CD1a
+
dendritic cells generated
ex vivo
from monocytes or hematopoietic precursor cells. CD1c (BDCA-1)
+
myeloid dendritic cells have been designated as type-1 myeloid dendritic cells (MDC1s). The CD1c antigen is a member of the CD1 family of proteins that are structurally related to MHC class I proteins and mediate the presentation of non-peptide antigens to T cells.
Additional information: Clone REA694 displays negligible binding to Fc receptors.
