Molecular Biology
Enzymes, DNA and Proteins for Molecular Biology Research
The Molecular Biology Product Line offers essential enzymes, nucleic acids, and proteins commonly used in research. A significant portion of these enzymes and proteins are recombinant, manufactured and purified from genetically engineered bacteria and yeast. This approach enables us to deliver animal component-free (Animal Free, AF) products, along with recombinant, Molecular Biology Grade and Bioprocess Grade items, ensuring safety and reliability across diverse applications.
The Bioprocess Grade Enzymes are specialized enzymes tailored to meet the stringent requirements of pharmaceutical and biomedical bioprocessing applications.
