Transgene copy number was quantified by Southern blot hybridization performed in triplicate. Murine c-fes RNA levels were given the arbitrary value 2, corresponding to the expression of both endogenous genes. Transgenic human c-fesRNA expression was compared with murine c-fes RNA levels and corrected for differences in gene copy number. For example, transgenic no. 3 (88 copies) would be expected to express 44 times as much humanc-fes RNA as murine c-fes RNA and listed as 100% of the expected value (2 copies). Thus, the value of humanc-fes expression is the volume of the human 273–base pair (bp) protected fragment (minus background) divided by the volume of the murine 288-bp protected fragment (minus background) and compared with the expected abundance on the basis of the copy number of each transgene. The value of human c-fes expression for all splenic samples is based on a single RPA autoradiogram for direct comparison.
