MLC and NK assays of G110. In vitro lymphocyte function of one representative dog, G110, compared with the donor dog and an unrelated control dog measured by MLC and NK assay. In the MLC (A), ³H thymidine uptake was measured as the mean counts per minute of triplicates, pretransplantation, on day –1, 31, and 55. In the NK assay (B) cytotoxicity is expressed as percentage of specific lysis pretransplantation, on day 31 and 55.
