Description

The A7R34 monoclonal antibody reacts with mouse CD127, the high affinity α subunit of the mouse IL-7 receptor. IL-7 receptor α chain is expressed by immature B cells in the bone marrow, double-negative (CD4^-/CD8^-), single-positive (CD4⁺ and CD8⁺), but not double-positive (CD4⁺/CD8⁺) thymocytes. In the periphery, mature T cells express CD127 at low level. A7R34 inhibits binding of IL-7 to its receptor and has been used in in vivo and in vitro studies to elucidate the role of IL-7 in T and B cell development and activation. Binding of A7R34 blocks the binding of SB/199, another antibody which recognizes mouse CD127.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The A7R34 antibody has been reported for use in flow cytometric analysis.

Applications Tested

The A7R34 antibody has been tested by flow cytometric analysis of mouse thymocyte and splenocyte suspensions. This can be used at less than or equal to 0.5 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
