(A) α1 RNA specifically inhibits the amplification
of α1 from a rat kidney cDNA template.
PCR was performed with 1 µM sense and
1 µM antisense degenerate primers and
rat kidney cDNA; without RNA (lane 1), with 50 nM α1
RNA (lane 2), with 50 nM β1 RNA (lane
3), with 50 nM β2 RNA (lane 4), with 50
nM α1 RNA and 50 nM β1 RNA
(lane 5), with 50 nM α1 RNA and 50 nM β2 RNA (lane 6), with 50 nM β1
RNA and 50 nM β2 RNA (lane 7) or with
50 nM α1 RNA, 50 nM β1
RNA and 50 nM β2 RNA (lane 8). After
electrophoresis and Southern blotting, the blot was hybridized with
a radiolabeled probe specific for α1,
washed at high stringency and subjected to autoradiography. A ladder
of molecular weight markers is on the left and the arrow indicates
the bands corresponding to the expected 750 bp PCR product. (B) β1 RNA specifically inhibits the amplification
of β1 from a rat kidney cDNA template.
