Clone REAL130 is an antibody fragment derived from the full CD4 antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAdye_lease Complex to bind markers with high avidity.
Clone REAL130 recognizes the mouse CD4 antigen, a cell surface glycoprotein, which is a member of the immunoglobulin superfamily. It is also known as L3T4 or Leu-3. In mice, CD4 is expressed on T helper cells, regulatory T cells, and at lower levels on subpopulations of NKT cells and dendritic cells. It is furthermore detected on most thymocytes (CD4+CD8+ and CD4+CD8– thymocytes). CD4 interacts with MHC class II molecules on the surface of antigen presenting cells. It increases the avidity of the interaction between T cells and antigen-presenting or target cells.
For removal of REAdye_lease fluorochromes for optional relabeling with different fluorochrome-conjugated REAdye_lease antibodies use the REAlease Support Kit (130-120-675).
