Study on construction of cDNA library of the treated Changliver cell and quality analysis

Abstract

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 × 1010 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.
