RESUMO
The study aims to construct cDNA library of Changliver cell by SMART (switching mechanism at 5' end of RNA transcript) technique and analyze its quality. cDNA of Changliver cell was made with RT-PCR and LD-PCR (long-distance PCR), the cDNA library was constructed with SMART cDNA library construction kit. Through testing, the high quality cDNA library containing whole long cDNA of Changliver cell had been constructed. The titer of the amplified cDNA library was 4.5 × 10(10) pfu/ml and the average exogenous inserts of the recombinants is 1.5 kb. These results showed that the Changliver cell cDNA library had an excellent quality and lay foundation for screening whole long cDNA of related genes.
RESUMO
Objective To construct cDNA library of the treated Changliver cell by switching mechanism at 5′ end of RNA transcript (SMART) technique and analyze its quality.Methods cDNA of Changliver cell was aquired with reverse transcription polymerase chain reaction (RT-PCR) and long-distance PCR (LD-PCR),then the cDNA library was constructed with SMART cDNA library construction kit.Results Through testing,the high quality cDNA library containing full length cDNA of Changliver cell had been constructed.The titer of the amplified cDNA library was 4.5 × 1010 pfu*ml-1 and the average exogenous inserts of the recombinants was 1.5 kb.Conclusion These results suggest that the Changliver cell cDNA library has a high quality and lays a solid foundation for researching on Changliver cell and screening
