Mixed Lymphocyte Reactions (MLR’s) provide researchers a tool to evaluate the immune response of a recipient to implanted tissues or devices. Lymphocytes isolated from the recipient are stimulated with non-proliferative lymphocytes isolated from the donor and the proliferative response is measured. Xeno Diagnostics utilizes DNA incorporation of BrdU to qualitatively determine the amount of cell proliferation. To ensure that only the proliferation of the recipient’s lymphocytes is being evaluated, the stimulator cells are rendered non-proliferative (“NP”) by mitomycin C treatment. The MLR can be used to evaluate:
Longitudinal MLR testing is available for non-human primates (baboon, cynomolgus macaque, rhesus monkey) for the evaluation of tissue and device implants.
