Abstract

Poly (lactic-co-glycolic acid) (PLGA) based particulate systems have been widely explored for the development of subunit based vaccines owing to its biodegradability, biocompatibility, controlled release of entrapped antigen, targeted delivery potential, and nontoxic degradation product. Here, we describe the preparation of PLGA encapsulated recombinant protective antigen domain 4 (PAD4) nanoformulation (PAD4-NP) and its characterization for antigen content, morphology, and size. We also discuss the method of immunization in mice models to evaluate such PLGA based nanoformulation vaccines.
