The PCR was performed as follows: 94°C for 5 min. followed by 30 cycles of 94°C for 30 s, 52°C for 30 s, 72°C for 30 s, and final extension at 72°C for 10 min., The PCR product was random prime 32P-dCTP labeled with the Random Primers DNA Labeling System (Life Technologies, Rockville, MD). The labeled probe was hybridized to human adult and fetal Multiple Tissue Northern (MTN) Blots (Clontech Laboratories, Palo Alto, CA., Cat. #7760–1, 7759–1 and 7756–1) in ExpressHyb solution according to manufacturer's directions. The final wash was at 50°C in 0.1XSSC, 0.1%SDS twice for 20 min each time. Exposure to Hyperfilm (Amersham-Pharmacia Biotech) was for four days at -80°C. Oligonucleotide primers Ndnl2-1F (5'-CTTGGAGTACCGGAGGATACC) and Ndnl2-2R (5'-CAACACATCCTAACGCTCCA) were used for mouse northern blots. These primers amplified a 343 bp DNA fragment corresponding to the 3' end of the Ndnl2 gene. The PCR was performed as above but with an annealing temperature of 58°C. Mouse adult and embryo MTN blots (Cat. #7762–1 and 7763–1, Clontech Laboratories) were similarly hybridized with the radioactively labeled Ndnl21F/2R PCR product. To control for the amount of loaded RNA the same blot was subsequently hybridized with a β-actin or ubiquitin probe demonstrating approximately equal loading in all lanes.","divisions":[{"label":"Title","span":{"begin":0,"end":32}}],"tracks":[]}
