Clone
Clone — A genetically identical copy of a gene, cell, or organism, used in recombinant peptide production to create cell lines expressing the target sequence.
What Is a Clone?
In molecular biology, a clone is a genetically identical copy of a DNA sequence, cell, or organism. In peptide research, cloning refers to inserting a peptide-encoding gene into an expression vector for recombinant production. The clone (vector + insert) is transformed into host cells (E. coli, CHO) for peptide expression.
Cloning for Peptide Expression
- Gene synthesis: Codon-optimized peptide gene synthesized and inserted into expression vector
- Fusion tags: His-tag, GST, SUMO fused to peptide for solubility and affinity purification
- Protease site: TEV or enterokinase cleavage site between tag and peptide for clean release
Frequently Asked Questions
