For the RT reaction, 200 U Tween buffer (137 mM NaCl, 2.7 mM KCl, 6.5 mM Na 2HPO4, of SuperScript III reverse transcriptase and 40 U of RNaseOUT 1.five mM KH2PO4, pH 7.two with five non-fat milk powder and had been used. The final reaction volume was 20 l. Samples had been 0.1 Tween 20). The immunodetection of CasC was accomplished very first incubated at 25 for ten min, then at 50 for 60 min, then by incubation of the membrane with anti-Cascade serum raised at 85 for 5 min and put on ice, thereafter.

Right after washing with Green I and a C1000 touch thermal cycler with optical reaction PBS/Tween buffer for 10 min the membrane was incubated in module CFX96 (Bio-Rad). RNA isolation and cDNA synthesis AP buffer (one hundred mM TRIS-HCl pH 9.five, 100 mM NaCl, five mM had been performed as described above. cDNAs derived from 1 g MgCl2) for 10 min and stained in ten ml AP buffer supplemented of total RNA had been diluted 1:10 in DEPC-treated water.
