Comparison of efficiency of complements from various species for T-cell depletion from Cercopithecus aethiops bone marrow with Campath-1 MoAb in vitro.

Mature T-cells were removed from Cercopithecus aethiops monkey bone marrow with Campath-1 MoAb plus complement from various species (man, rabbit and monkey). The T-cell depletion was more effective and stable with rabbit or human complement than with autologous (monkey) complement. The most complete and effective lytic function to T-cells was found in the case of rabbit complement. Rabbit complement can be used successfully to deplete bone marrow T-cells of C. aethiops with Campath-1 in vitro.
