2.Construction of Full-length cDNA Library

Schematic representation of the "Oligo-capping" method

The cap structure of the mRNA is replaced with a 5'-oligo by the "Oligo-capping" method, which consists of three enzymatic reaction steps. Bacterial alkaline phosphatase (BAP) hydrolyses the phosphate of truncated mRNA 5'-ends whose cap structures have been broken down. Tobacco acid pyrophosphatase (TAP) removes the cap structure, leaving the phosphate at the 5'-end. T4 RNA ligase, which requires a phosphate at the 5'-end as its substrate, selectively ligates the 5'-oligo to the 5'-end that originally had the cap structure.
