Rapid amplification of cDNA ends (RACE) has widely been used to determine both ends of the cDNA from its partial sequence. Conventionally, 5'- and 3'-RACE products were ligated at a restriction site in the overlap region to reconstruct the full-length cDNA; however, reconstruction is difficult if no appropriate restriction enzymes are available. Here, we report a novel method to reconstruct full-length cDNA with DNA polymerase. Instead of usual PCR, chain reactions were avoided and the elongation time was shortened, which enables non-specific products or undesired point mutations to be minimized. We successfully reconstructed and TA-cloned a full-length cDNA of echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) fusion gene variant 2 from RACE products obtained from a surgically resected lung adenocarcinoma sample. We also evaluated some parameters to provide recommendations for this new method.
