Detects human granulocytes, monocytes and platelets. X-6 detects an antigen of 154-180 kDa by immunoprecipitation. Antigen distribution on Isolated cells and Tissue sections: Granulocytes, monocytes. Positive on blood monocyte-derived macrophages days 0-28. Dull staining with 95 % cord blood CD34 cells. Weak reaction on resting neutrophils. Staining increase with maturation of granulocytes. Treatment with fMLP, TNF, GM-CSF and temperature causes postive shift with granulocytes and monocytes. PMA treatment of granulocytes leads to decrease in no. of positive cells. X-6 is positive on lining cells in different infiltrations and endothelial cells in the synovial membrane of RA patients. The staining pattern is similar to CD34 in these patients.
Suitable for Immunohistochemistry on frozen sections (2 μg/mL (1: 100) and FACS (use 10 μLstock solution to label 10^6 cells). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

The X-6 antibody is useful for the detection of the fibronectin receptor, or CD49e. CD49e is a component of an adhesion receptor heterodimer (α5β1) to fibronectin and invasin. α5β1 recognizes an Arg-Gly-Asp sequence in fibronectin. Binding of fibronectin through α5β1 is important for cell survival and induces apoptosis, particularly in hemopoietic cells.Synonyms: CD49 antigen-like family member E, FNRA, Fibronectin receptor subunit alpha, Integrin alpha-5, Integrin alpha-F, VLA-5, VLA5
