DGGE PCR. cDNA of three to five larvae per tank were
combined into two pools. A nested PCR was performed with the
DGGE_f_cl [44] and DGGE677R [45] primers (Table 1) and as
described in Jung-Schroers et al. [43] with 0.2 U hot-start KAPA 2 G
robust polymerase (PeqLab), 1 KAPA A buffer, 200 nM of each
primer, 200 mM of each dNTP, 18.4 ml of 10 diluted cDNA in a final
volume of 25 ml.
