Product Specific Information

Highest antigen sequence indentity to the following orthologs: Mouse (33%), Rat (33%).

This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-83447. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

Target Information

CD7, also known as gp40 or Leu9, is a 40 kDa receptor and member of the immunoglobulin gene superfamily. It features an N-terminal region (amino acids 1-107) that is highly homologous to Ig kappa light chains, while its carboxyl-terminal region is proline-rich, forming a stalk from which the Ig domain projects. CD7 is prominently expressed on the majority of immature and mature T lymphocytes, as well as T cell leukemias. It is also found on natural killer cells, a small subpopulation of normal B cells, and malignant B cells. CD7 plays a crucial role in modulating immune cell activity. Cross-linking of surface CD7 enhances T cell and NK cell functions, as evidenced by increased calcium flux, expression of adhesion molecules, cytokine secretion, and proliferation. CD7 directly associates with phosphoinositol 3-kinase, and its ligation induces the production of D-3 phosphoinositides and tyrosine phosphorylation. The expression of CD7 is an important marker in leukemia diagnostics, highlighting its significance in both normal immune function and disease states.
