Figure 11 Polymerase chain reaction (PCR) analysis of the UDP‐GTA gene following digestion with the restriction enzyme MavI. Acrylamide gel electrophoresis of the amplification product of the cDNA from wild type and Gunn j/j rats yields different patterns after digestion with the restriction enzyme. In Gunn j/j rats, which received infusion of bone marrow derived cells (BMDCs) from non‐affected, wild type animals, four bands are visible, including those derived from digestion of the normal enzyme (384 and 123 bp).
