Splet20. jan. 2024 · A single pair of PCR primers will amplify either a 50bp fragment ( B2 ), a 60bp fragment ( B3 ), or a 100bp fragment ( B4 ). Draw the PCR bands that would be expected if these primers were used to amplify DNA from individuals with each of the following genotypes: a) B2B2 b) B4B4 c) B2B3 d) B2B4 SpletMultiple bands indicate sequence duplications (Figure 1). PCR cleanup The goal of PCR cleanup is to remove the excess PCR primers (one primer is used in each sequencing reaction) and dNTPs (to preserve the ratio of the dNTP to ddNTP necessary for efficient Applied Biosystems™ BigDye™ Cycle Sequencing reactions). SpletAfter electrophoresis, bands should be easily visible. If bands are faint, the amount of template for sequencing can be increased. Very faint bands indicate insufficient quantities for sequencing. Example for template gel with purified PCR products The bands in lanes 4, 5, 6 indicate sufficient quantities of DNA for sequencing. matt huisman twitter
