Verify that primers have no additional complementary regions within the template DNA. Verify that primers are non-complementary, both internally and to each other. Primer concentration can range from 0.05–1 µM in the reaction. Please see specific product literature for ideal conditions. WebUsing too few PCR cycles can lead to insufficient amplification. Use 20–35 cycles. Use fewer cycles when template concentration is high, and use more cycles when template concentration is low.
