Properdin protein concentrations and mRNA levels in complement-deficient mice. (A) DAF^−/− and Cr2^−/− mice (representative of six for each type). (B) Properdin and GAPDH mRNAs in WT, C3^−/−, and Crry SKO mice (C) as well as in fB^−/− and fD^−/− mice. Total RNA was extracted from bone marrow cells, cDNA was synthesized by random primers, and properdin and GAPDH mRNAs were identified by specific primers. Representative of three deficient mice for each mouse strain.
