Antibiotic Resistance Marker Removal

Introduction

The use of antibiotic resistance genes as selection markers in synthetic biology strains has been a common practice for many years. However, the increasing concern over the spread of antibiotic resistance has prompted scientists to develop alternative selection systems. The use of antibiotic-free selection systems is not only a safer option but also more cost-effective in the long run.

CD Biosynsis recognizes the importance of antibiotic resistance marker removal in synthetic biology strains, and offers a range of services to assist researchers in this field. Our team of experts has extensive experience in the development and optimization of alternative selection systems, and we use the latest technologies and techniques to ensure the highest quality results.
