Figure 3. T4 polynucleotide kinase does not preferentially label m6Am or Am containing ends.

Figure 3

The oligonucleotides SK-526 (m6Am) and SK-524 (Am) were mixed in ratios of 5:1, 2:1, 1:1. 1:2 and 1:5, end labelled using T4 polynucleotide kinase, digested to 5' phosphate mononucleotides and separated by TLC. The relative intensities of the resulting spots were quantified using phosphorimaging. The calculated percentage of m6Am closely matched the actual m6Am percentage.
