CD19 MicroBeads, human

CD19 MicroBeads, human

CD19 MicroBeads were developed for positive selection or depletion of CD19
+
B cells from different cell sources such as human PBMCs, bone marrow, lymphoid tissues, or cell cultures.

Background information

As a B cell lineage marker, the CD19 antigen is expressed from the early pro-B cell stage to the B cell lymphoblast stage, but the expression is down-regulated upon B cell maturation to plasma cells. The CD19 antigen is further expressed on most malignant B cells and on a subset of follicular dendritic cells.

Downstream applications

Isolated CD19
+
B cells were used for studies on immunoglobulin production, such as IgE synthesis
1, 2
and secretion
3
, chemotaxis assays
4
, or mixed lymphocyte reactions. Positively selected CD19
+
B cells were also used for molecular studies such as gene expression profiling.
5
For the analysis of minimal residual diseases in B cell malignancies, enrichment of B cells increases the sensitivity of detection.
