| Description |
| Mouse CD19 MicroBeads are used for the positive selection or depletion of mouse B cells from peripheral blood and various tissues such as bone marrow, lymph nodes, and spleen. CD19 is expressed on B lineage cells throughout their development from the early pro-B cell stages onwards and is down-regulated upon terminal differentiation to plasma cells. |
| Applications |
| B cells isolated with CD19 MicroBeads were used to study the accessibility of enhancer elements during B cell development by in vivo footprinting.1 Cell extracts prepared from purified B cells were used to analyze conditions for V(D)J recombination in a cell-free system.2 Furthermore, mRNA was isolated from selected B cells for microarray analyses to quantify transcription factor expression during B cell development.3 |
