Antigen preparation service

Service introduction
Obtaining high-quality antigens is one of the key factors for the success of antibody development. Rongtai Biotech can provide protein antigen and peptide antigen preparation services. The protein antigen has a more complete conformation. When the protein in the sample to be tested is in the natural conformation, the protein antigen immunity is preferred, such as the development of neutralizing antibodies. When the expression of full-length protein is difficult or there are other special requirements for detection specificity, peptide antigen is the only economic and practical choice. In addition, Rongtai Biology can also provide diverse immune means such as DNA, cells and insect viruses to solve the problem that protein antigens are difficult to recombine and express.
