Plasmacytoid Dendritic Cell Isolation Kit II, human

The Plasmacytoid Dendritic Cell Isolation Kit II allows the isolation of untouched human plasmacytoid dendritic cells (PDCs) from PBMCs. Having evolved from the first-generation kit (# 130-092-207), it now offers even better cell purity and yield in a faster procedure.

Background information

The isolated PDCs are CD303 (BDCA-2)
+
, CD304 (BDCA-4/Neuropilin-1)
+
, CD123
+
, CD4
+
, CD45RA
+
, CD141 (BDCA-3)
dim
, CD1c (BDCA-1)
, and CD2
. The cells lack expression of lineage markers (CD3, CD14, CD16, CD19, CD20, CD56) and express neither myeloid markers, such as CD13 and CD33, nor Fc receptors, such as CD16, CD64, or FcεRI.

Detailed separation procedure

PDCs are isolated by depletion of non-PDCs. To this end, non-PDCs are magnetically labeled by using cocktails containing specific MicroBeads, biotin-conjugated antibodies, and Anti-Biotin MicroBeads. Magnetically labeled cells are retained in the column, while unlabeled PDCs with high purity are collected in the flow-through.

Downstream applications

PDCs isolated from human PBMCs can be used for phenotypic, functional, and molecular analyses, e.g., studies on expression of Toll-like receptors, chemokine receptors, or new antigens, and on DC activation, migration, cytokine production, and T cell polarization.
The Plasmacytoid Dendritic Cell Isolation Kit can also be used to enrich PDCs from tonsils, if the CD303 (BDCA-2) MicroBead Kit is not suitable.
