Resumen

DNA cloning is an essential tool regarding DNA recombinant technology as it allows the replication of foreign DNA fragments within a cell. pELMO was here constructed as an in-house cloning vector for rapid and low-cost PCR product propagation; it is an optimally designed vector containing the ccdB killer gene from the pDONR 221 plasmid, cloned into the pUC18 vector’s multiple cloning site (Thermo Scientific). The ccdB killer gene has a cleavage site (CCC/GGG) for the SmaI restriction enzyme which is used for vector linearisation and cloning blunt-ended products. pELMO transformation efficiency was evaluated with different sized inserts and its cloning efficiency was compared to that of the pGEM-T Easy commercial vector. The highest pELMO transformation efficiency was observed for ~500 bp DNA fragments; pELMO vector had higher cloning efficiency for all insert sizes tested. In-house and commercial vector cloned insert reads after sequencing were similar thus highlighting that sequencing primers were designed and localised appropriately. pELMO is thus proposed as a practical alternative for in-house cloning of PCR products in molecular biology laboratories.
