CD1c (BDCA-1) antibodies, human

Clone: AD5-8E7 | Dilution: 1:11
The clone AD5-8E7 recognizes human CD1c, 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
, CD123
, CD4
, Lin
, CD45RO
, CD2
, CD16
, CD141 (BDCA-3)
, 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.
