DNA-protein conjugates have recently been explored for many biomedical applications, including the delivery of antibodies and enzymes and cancer therapy. Creative Biolabs has been a long-term expert in the field of cell conjugate. Due to the advanced technology platforms and extensive experience for DNA-protein conjugate, our seasoned scientists have set up one-stop procedures to assist your DNA-protein conjugation demands with the highest efficiency and the best quality.

DNA-Protein Conjugate

DNA and protein are the most critical two classes of biomacromolecules forming the basis of life. Given the high selectivity of DNA molecules, it is desirable to combine them with the functional versatility of proteins. The conjugation of the two enables a combination of molecular recognition, enzymatic catalysis, and Watson-Crick hybridization properties. DNA-protein conjugates, with their combined properties, have a broad range of applications, such as in high-performance biomedical diagnostic assays, therapeutic agents, fundamental research on molecular recognition, and DNA nanostructures synthesis. Moreover, these conjugates have been used as carriers in drug-delivery systems to deliver enzymes or available drugs for disease treatments.
