Description: This 5H12 monoclonal antibody reacts with mouse Autoimmune Regulator (AIRE). This 58-kDa transcription factor is highly expressed within the perinuclear region of mature medullary thymic epithelial cells (mTECs). However, expression of AIRE protein in the periphery remains unclear despite the detection of AIRE mRNA in the lymph node, lymphoid stromal cells, monocytes, and dendritic cells. Studies demonstrate that AIRE is involved in thymocyte development, in particular the regulation of tissue-specific antigen expression during negative selection. Other biological functions for AIRE include chemokine expression and antigen presentation.
The 5H12 antibody recognizes mouse AIRE isoforms 1 and 2.
