Transcription activator like effector nucleases (TALENs) are artificial restriction enzymes generated by fusing a TALE DNA binding domain to a DNA cleavage domain which remove and introduce specific genes to produce transgenic animals. To investigate the efficient laboratory techniques for the injection of TALEN mRNA, pEGFP-N1 commercial plasmid were microinjected into porcine parthenogenetic and in vitro fertilization (IVF). In Experiment 1, to investigate injection time, compared 4 different time durations (2 hr, 4 hrs, 6 hrs & 8 hrs) after post activation of parthenogenetic embryos and after 6 hrs of co-incubation with sperms in IVF embryos. There were significant difference (P<0.05) in development to the blastocysts (4.4, 8.9, 3.9, 0.6%), GFP expression in blastocysts (1.3, 5.7, 2.3, 0.0%) which injected after post activation of 4 hrs compared with other 3 groups. IVF embryos after 2 hrs and 4 hrs injected were expressed GFP significantly higher than rest of two groups (P<0.05). In Experiment 2, compared development of 2 different concentrations (20 ng/μl and 50 ng/μl) of EGFP injection. There were significant difference (P<0.05) between two treatments which has higher cleavage (58.8 vs 41.9%), blastocysts development rate (13.0 vs 11.1%) and GFP expressed blastocysts (5.7 vs 0.0%) in 20 ng/μl than the 50 ng/μl in parthenogenetic embryos. In IVF embryos, only 20 ng/μl injected embryos were expressed GFP (4.2%) after 7 days of incubation and 77.3 vs 64.7% of cleavage, 26.4 vs 23.5% development to blastocysts. In Experiment 3, three different volumes (5, 10 and 20 pl) were microinjected into porcine embryos to determine the most appropriate volume. Out of 3 groups, significantly higher development rates of cleavage (68.3, 58.0, 29.3%), blastocysts (11.7, 12.7, 0.5%) and GFP expressed blastocysts (2.9, 7.8, 0.0%) were shown in the 10 pl group (P<0.05). In conclusion, these results imply that 20 ng/μl concentration, 10 pl of volume and injection at 4 hrs after post activation for parthenogenetic and 2∼4 hrs after IVF, 20 ng/μl concentration and 10 pl volume for IVF embryos were more effective microinjection conditions.
