CD16+ Monocyte Isolation Kit, human

The CD16 Monocyte Isolation Kit has been developed for a two-step isolation of the CD14,CD16 monocyte subset from PBMCs.

Background information

Intermediate and non-classical monocytes together are referred to as CD16
+
 monocytes
1
 and account for about 5–10% of all blood monocytes. CD14
+
CD16
+
 monocytes differ from CD14
+
CD16
-
 monocytes with regard to phenotype and immunological function. CD16
+
 monocytes are, for example, considered more mature and are believed to have a higher T cell stimulatory capacity than CD16
-
 monocytes.

Detailed separation procedure

Isolation of CD16
+
 monocytes is performed in a two-step procedure. Prior to separation, cells are incubated with FcR Blocking Reagent. Granulocytes and NK cells are then magnetically labeled with a cocktail of CD15 MicroBeads and CD56 MicroBeads, and depleted over a MACS Column. The flow-through in this first separation step contains pre-enriched, unlabeled CD16
+
 monocytes. In the second separation step, CD16
+
 monocytes are efficiently isolated by positive selection after labeling with CD16 MicroBeads.

Downstream applications

Isolated blood CD16
+
 monocytes are suitable, for example, for investigations on CD16
+
 monocyte maturation, migration, and differentiation, or for studies on antigen uptake, antigen processing and presentation to T cells.
