To enable precise introduction of multiple site-directed mutations in genes.

Main Methods:

Utilized type IIs restriction enzymes for gene mutagenesis.
Amplified template genes into two PCR fragments with specific primers.
Ligated digested fragments with complementary cohesive ends to create mutated genes.

Main Results:

Achieved perfect mutagenesis efficiency at desired sites.
Successfully introduced multiple site-directed mutations in EGFP and Bcl-2 family genes.
Demonstrated a rapid and efficient mutagenesis process.

Conclusions:

The described type IIs restriction enzyme-based method is efficient and cost-effective.
This technique is applicable to a wide range of structural and functional studies in cell physiology.
Offers a valuable tool for molecular biology and protein engineering research.
