Overview of the DNA and Protein Co-Immunization Strategy
DNA immunization is a technique featuring with inducing in vivo immune activities by delivering DNA into the host. Early studies of immunization mostly focused on triggering cytotoxic T-cell activities, then gradually turned to B-cell activities and antibody production. One attractive feature of DNA immunization is to directly generate in vivo antigen. Conventional immunization methods are based on the recombinant proteins or coupled peptides, which have difficulty in generating protein with naïve conformation, transmembrane protein or protein conjugated with ion channels. Moreover, the synthesis and purification of protein and peptide antigen are time-consuming and costly, especial for problematic proteins. DNA immunization method can bypass these barriers and is able to produce protein/peptide with natural folding and structural integrity, which can be missing during in vitro synthesis. However, naked DNA immunization is reported to display relatively low immune response during immunization process, especially for the large animals, such as monkey, camel, and llama. In order to elevate B-cell activities and improve the quality of antigen, a strategy called heterologous or co-immunization is developed base on naked DNA immunization, namely using target DNA for priming immunization and followed by protein/peptide antigen or other vaccines boost. This strategy is more effective than homologous prime-boost immunizations using multiple doses of the same recombinant proteins or target DNA.

Immunization with Protein/Peptide/Hapten
Creative Biolabs has extensive experience in conducting coupled peptide and protein immunization as independent or boosting for heterologous immunization. We offer comprehensive services including target antigen synthesis, purification, antigen conjugation (for peptide and hapten), immunization, and titration. Due to the small size and simple structure, peptide/hapten may need to couple with a carrier molecule to increase immunogenicity. Technicians in Creative Biolabs are able to conjugated peptides/hapten with appropriate carrier protein including keyhole limpet hemocyanin (KLH), ovalbumin, and bovine serum albumin (BSA), to dramatically elevate immune responses.
Comprehensive DNA Immunization Strategies
According to our experienced technical staffs in DNA immunization realm, Creative Biolabs is able to offer comprehensive methods to deliver the DNA to the host animals. The unique Magic™ DNA immunization is one of the feature strategies which can induce good immune response through formulated DNA expression plasmid. Moreover, in vivo electroporation and gene gun strategies can contribute to increasing immune response from delivered DNA plasmid as well.
With our years of experience, scientists from Creative Biolabs are pleased to tailor the best-fit strategies for our clients’ project to meet the specific requirements. We can also develop antibodies from a series of novel sources through our DNA immunization services, which including but not limited to:
