Purpose of the Study:
- To present TmPrime, a flexible computer program for designing oligonucleotide sets for gene assembly.
- To enable gene assembly using ligase chain reaction (LCR) and polymerase chain reaction (PCR).
- To provide tools for sequence pooling and codon optimization.
Main Methods:
- TmPrime divides DNA sequences based on desired melting temperature.
- It dynamically optimizes oligonucleotide lengths for homologous melting temperatures.
- The program analyzes potential secondary structures and reports melting temperatures and sequences.
Main Results:
- Successfully designed and synthesized genes including GFPuv, PKB2, and S100A4 promoter.
- Utilized real-time PCR assembly with LCGreen I for gene synthesis efficiency comparison.
- Demonstrated purity estimation using melting curve analysis, potentially replacing gel electrophoresis.
