Recombinant DNA
Recombinant DNA — DNA molecules formed by combining genetic material from multiple sources, the basis for producing recombinant peptides in expression systems.
What Is Recombinant DNA?
Recombinant DNA is artificially created DNA combining sequences from different sources, used to produce recombinant peptides in host organisms. The peptide-encoding gene is inserted into an expression vector, transformed into an expression host, and the peptide is produced by the host's translational machinery.
Workflow
- Gene design: Codon-optimize peptide gene for host organism. Add fusion tag if needed
- Cloning: Insert into expression vector with promoter, RBS, and selection marker
- Expression: Induce peptide production (IPTG for E. coli T7 system)
- Recovery: Lyse cells, purify peptide by affinity + polishing chromatography
