Simple cDNA library preparation with the PrimeScript Double Strand cDNA Synthesis Kit
The PrimeScript Double Strand cDNA Synthesis Kit contains all of the reagents necessary to synthesize double-stranded cDNA from purified poly A+ RNA templates using the Gubler-Hoffman method (Gubler and Hoffman 1983). First-strand cDNA is synthesized using PrimeScript RT and either oligo(dT) primers or random primers. After cDNA synthesis, E. coli RNase H7 is used to nick the RNA portion of mRNA-cDNA hybrids. E. coli DNA Polymerase I is subsequently used for second-strand synthesis by nick translation, and E. coli DNA Ligase repairs breaks in the second strand. Finally, T4 DNA Polymerase is used to blunt the ends. The resulting double-stranded cDNA can be cloned into an appropriate vector to generate a cDNA library.
Overview
- Includes high efficiency PrimeScript Reverse Transcriptase to synthesize first-strand cDNA from purified poly A+ RNA
- The resulting double-stranded cDNA can be cloned into an appropriate vector to generate a cDNA library
- This kit contains positive control RNA, which can be cloned into a selectable plasmid to confirm success
More Information
Applications
- Synthesis of double-stranded cDNA using the Gubler-Hoffman method (Gubler and Hoffman 1983)
- Construction of cDNA libraries
*The Control RNA is a 1.4-kb poly(A)+ RNA from the tetracycline resistance gene that can be used as a positive control. When full-length double-stranded cDNA is synthesized from this RNA template and cloned, the resulting plasmid confers tetracycline resistance.
