Since the outbreak of novel coronavirus (SARS-CoV-2) in various regions of the world, the research and development (R&D) of small-molecule drugs and biologics targeting novel coronavirus have been intensified and achieved some breakthroughs. The selection of the correct antigen is one of the most critical steps in a successful antibody development project. Drawing on our expertise in protein structural biology, Creative Biostructure currently provides custom antigen design and preparation services for the therapeutics development for coronavirus infection. Based on the application of antibodies, we will comprehensively consider many factors such as homology, molecular weight, purity, length, hydrophilic, and structure to help you design and prepare the optimal antigen.
