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. This A7R34 antibody has been reported for use in flow cytometric analysis.
The photo-emission properties and compensation required for Alexa FluorŽ 750 are similar to APC-Cy7; however Alexa FluorŽ 750 has several advantages when compared to APC-Cy7. The Alexa FluorŽ 750 has peak emission of 779 nm, and usually has a slightly higher mean fluorescent intensity when compared to the same clone conjugated with APC-Cy7, which has peak emission of 767 nm. Furthermore, Alexa FluorŽ 750 is considered to be a more photostable fluorochrome as compared with APC-Cy7. It is advised not to use fixatives with Alexa FluorŽ 750 as this may lead to degradation of the fluorochrome and loss of staining.
Applications Tested
This A7R34 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.25 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.
