T-Cell Xtend is an antibody complex directed against specific cell surface antigens
on human blood cells
• T-Cell Xtend cross-links selected white cells, that may interfere with ELISPOT
assays, with red blood cells
• This cross-linking increases the density of selected cells so that they form a pellet
when applied to a density gradient
The use of T-Cell Xtend allows the T-SPOT®.TB assay to be performed on blood samples up to 32 hours after venepuncture without any change in accuracy of the test.
