Astor Recombinant Proteins
What Are Recombinant Proteins?
Recombinant proteins are laboratory-produced proteins generated by inserting an engineered DNA sequence into a host such as bacteria, yeast, insect, or mammalian cells. This method enables strict control over sequence design and expression, ensuring proteins with desired structure and functionality.
Compared with naturally extracted proteins, recombinant forms are ideal for biotechnology, medicine, and diagnostics, supporting disease research, drug development, and vaccine production with improved reproducibility and scalability.
